Manual of the New Zealand Flora/Compositæ
Order XXXVIII. COMPOSITÆ.
Herbs, shrubs, or small trees. Leaves alternate, rarely opposite or whorled; stipules wanting. Inflorescence composed of one or many flower-heads (capitula), each consisting of numerous minute flowers (florets) sessile and densely packed on the enlarged tip of the flower-stalk (receptacle), surrounded by an involucre of whorled bracts and resembling a single flower. Heads either solitary and terminal (rarely axillary) or arranged in corymbose cymes or panicles, sometimes contracted into clusters or even compound heads. Involucre of few or many bracts (scales of the involucre) arranged m one or several rows. Receptacle either naked (no bracteoles mixed with the florets) or with bracteoles in the shape of chaffy scales or bristles (paleæ) placed at the outside of most or all of the florets, sometimes with the surface pitted or honeycombed. Florets many or few (very rarely 1), either all of one kind as regards sex, when the heads are said to be homogamous, or of more than one kind, when they are called heterogamous. The homogamous heads either have all their florets tubular and hermaphrodite (discoid) or all ligulate and hermaphrodite (liguliflorous). The heterogamous heads frequently have the central florets tubular and hermaphrodite or male, and the outer ones ligulate and female or neuter. The heads are then said to be radiate. The tubular florets in the centre are called florets of the disc, or simply disc-florets; the ligulate ones florets of the ray, or ray-florets. Heterogamous heads are also discoid when the marginal female florets have tubular corollas instead of ligulate. Calyx superior, adnate to the ovary and hardly to be distinguished from it; limb either wanting or composed of scales, bristles, or hairs, and then called pappus. Corolla gamopetalous, superior, either tubular or campanulate with 4–5 valvate lobes, or ligulate with the lobes cohering into a strapshaped lamina which spreads to one side. Stamens 4–5, inserted on the tube of the corolla and alternate with its lobes; filaments usually free; anthers united into a sheath surrounding the style, cells sometimes produced at the base into bristle-like points or tails. Ovary inferior, 1-celled; style slender, 2-fid, branches short or long, linear, usually semi-terete, furnished with variously placed and arranged collecting-hairs for sweeping the pollen from the anthercells, margins stigmatic; ovule solitary, erect, anatropous. Fruit a small dry seed-like nut called an achene, either crowmed by the persistent pappus or naked. Seed erect, with a membranous testa; albumen wanting; embryo straight, radicle short, inferior.
A vast order, by far the largest of flowering plants, comprising about 800 genera and 10000 species. It is found in every part of the world, from the equator to the limits of phænogamic vegetation in the arctic and antarctic regions, and is equally plentiful in lowland districts and in mountainous or alpine situations. In New Zealand it constitutes rather more than one-seventh of the total number of flowering plants, a somewhat large proportion, the ratio of the whole order to the flowering plants of the world being generally estimated at about one-tenth. Although so numerous in species, the order is far from being proportionately important from an economic point of view. Edible species are singularly few, the chief being the Jerusalem and common artichoke, lettuce, and chicory. Oils are yielded by the sunflower and by Madia sativa. The chief medicinal plants are arnica, wormwood, and camomile. Many ornamental species are cultivated in gardens, as the various Isinds of chrysanthemums, dahlias, cinerarias, asters, sunflowers, zinnias, marigolds, &c.; but on the whole it must be confessed that the majority of the plants composing the order present a weedy and unattractive appearance. Of the 26 indigenous genera 16 are widely spread; 5 extend to Australia alone (Brachycome, Olearia, Celmisia, Raoulia, Craspedia), but of these Celmisia and Raoulia are very feebly represented outside New Zealand. One genus (Cassinia) reaches South Africa as well as Australia; one (Abrotanella) occurs in Australia, Tasmania, and antarctic South America. The three remaining (Pleurophyllum, Haastia, Brachyglottis) are endemic. Many weeds of cultivation belonging to the order have become naturalised in the colony, a list of over 60 species being given in the appendix. Most of these are from the Northern Hemisphere, and descriptions of nearly all will be found in any British Flora.
Owing principally to the large size and homogeneous character of the order, very great difficulty has always been experienced in arranging the species in suitable genera and tribes, and the classification is still in an unsettled state. As there are no important differences in the flower and fruit, it becomes necessary to use minor characters, such as the shape of the style branches; the sexual differences of the florets composing the heads; the shape of the corolla; the absence or presence of minute tails to the anthers; the various modifications of the pappus; and the minute differences in tiie shape and sculpture of the ripe fruit or achene. Considerable practice is required before these distinctions can be understood, and a beginner will find it no easy matter to refer the species to their proper genera. His best plan will be to induce some friend to name a few for him, and then to carefully compare these with the specific, generic, and ordinal characters given in this book, or in other works on the flora. By so doing he will insensibly acquire a practical knowledge of the characters used in distinguishing the species and genera which will ultimately enable him to identify them for himself. In using the subjoined key to the New Zealand genera it must be remembered that the minute differences in the shape of the style-branches, so largely employed to separate the tribes from one another, can only be observed in the hermaphrodite florets, the style of tbe female florets being very similar throughout the order.

L. linearis, Petrie in Trans. N.Z. Inst. xxv. (1893) 471, is Brachycome lineata, Kirk. L. emphysopus, Hook. f., an Australian species, has become naturalised on Banks Peninsula and near Wellington. It has the habit, fleshy roots, and hirsute leaves of L. lanata, but can at once be distinguished by the short stout scapes and almost tubular ray-florets.
1. L. Forsteri, D.C. Prodr. v. 307.—A small daisy-like herb, either tufted or with creeping and rooting stolons furnished with tufts of radical leaves at the nodes. Leaves all radical or cauline, 1½–2in. long; petiole long, slender; blade ½–1 in., orbicular or orbicular-oblong to obovate, obtuse, narrowed into the petiole, coarsely crenate-dentate or almost lobed, almost glabrous or more or less hirsute. Scape 1–6 in. long, slender, naked or with 1–3 minute linear bracts. Heads ¼–½ in, diam.; involucral bracts linear, acute; margins thin, scarious, entire or finely jagged.

Zel. 231, t. 30.
Kermadec Islands, North and South Islands, Stewart Island, Chatham Islands: Abundant throughout, ascending to 3000ft. Papataniwhaniwha; Native Daisy. October–February.
A variable plant, very closely connected with the three following species.
2. L. petiolata, Hook. f. Fl. Nov. Zel. i. 125.—Habit of L. Forsteri, but smaller and much more slender. Leaves usually radical, spreading, ½–1½ in. long; petiole slender, half the length or more; blade variable in shape, obovate to orbicular, sometimes broader than long, obtuse, rather thin, acutely coarsely toothed with the teeth apiculate, more or less hairy on looth surfaces, often purplish beneath. Scape very slender, strict, 2–6 in. long, usually hirsute. Heads small, 15–13 in. diam.; involucral bracts linear, acute, often purplish at the tips; margins scarious. Ray-florets numerous; ligule very narrow, revolute. Achenes rather longer and more turgid than in L. Forsteri, linear-obovate, curved or falcate, slightly glandular above, narrowed into a rather long beak; margins thickened.—Handb. N.Z. Fl. 137; Kirk, Students' Fl. 257. L. strangulata, Col. in Trans. N.Z. Inst. xxii. (1890) 471.
Var. minima, Cheesem.—Very small, ½–2 in. high. Leaves with the petiole ½–1 in. long, membranous, dentate, sometimes lobed or pinnate at the base. Scapes filiform. Heads small.—L. Forsteri var. minima, Kirk, l.c.
North and South Islands, Stewart Island: Not uncommon from the Upper Thames and Waikato southwards, ascending to 4000 ft. November–January. Var. minima: Moist rocks by the side of streams; Bay of Islands to Te Aroha.
Very closely allied to L. Forsteri, but separated by the more slender habit, smaller and thinner leaves, smaller heads with shorter and narrower rays, and longer and narrower curved achenes. Mr. Kirk places the var. minima under L. Forsteri, but to me it appears much nearer to L. petiolata.
3. L. Barkeri, Kirk, Students' Fl. 257.—Stems leafy, slender, erect, 3–9 in. high. Leaves cauline, usually gradually diminishing in size upwards, 1–2 in. long; petiole about half the length; blade obovate-spathulate to narrow oblong-spathulate, obtuse or subacute, gradually narrowed into the petiole, coarsely crenate-dentate, scaberulous on both surfaces. Scape shorter or longer than the leafy part of the stem, scaberulous and pilose. Head ⅓–½ in. diam.; involucral bracts linear, acute, thin, often purplish. Ray-florets numerous; ligules white, revolute. Ripe achenes not seen.
South Island: Nelson—Sphagnum swamps in the Clarence Valley and near Lake Tennyson, T. F. C. Canterbury—By the Porter River, Kirk! Craigieburn Mountains, Cockayne! Cass River, near Lake Tekapo, T. F. C. 1500–3500 ft. December–January.
Far too closely allied to L. Forsteri, from which it only differs in the leafy stems, narrower scaberulous leaves, and (according to Kirk) in the linear short-beaked achenes.
4. L. purpurea, Kirk, Students' Fl. 257.—"Stems leafy below, naked above, erect, slender, grooved, 4–6 in. high, pubescent or puberulous. Leaves (including the petiole) 1½ in. long, membranous, ovate, radical and cauline, rather distant, truncate at the base, rounded at the apex, serrate or crenate-serrate, teeth apiculate, pubescent on both surfaces, ciliate, purple beneath. Heads ⅓–½ in. diam.; involucral bracts in about 3 rows, linear, acute, with scarious margins, keeled, midrib distinct, often tipped with purple. Achenes oblanceolate, compressed, with a rather long beak and thin margins."
South Island: Otago—Catlin's River, Kirk!
This appears to be founded on three immature specimens in Mr. Kirk's herbarium, and in the absence of additional information I have reproduced his description. It is probably nothing more than a large state of L. petiolata.
5. L. pinnatifida, Hook. f. Fl. Nov. Zel. i. 126.—Softly hairy or pilose in all its parts. Leaves all radical, spreading, 1–3 in. long, narrow obovate-oblong or obovate-spathulate, obtuse at the tip, narrowed into a long broad petiole, membranous, deeply crenatelobed or almost pinnatifid; margins ciliate. Scapes 3–10 in. long, slender. Heads ¼–½ in. diam.; involucral bracts linear, acute, pubescent. Ray-florets numerous; ligules narrow, revolute. Achenes compressed, obliquely linear-obovate, narrowed to the base, suddenly contracted at the tip into a short straight neck, more or less glandular-pubescent; margins thickened.—Handb. N.Z. Fl. 137; Kirk, Students Fl. 258.
North Island: Auckland, Sinclair; sandhills near Helensville, T. F. C.; East Cape, Colenso! South Island: Nelson-Wairau Valley, Kirk! T. F. C.; Marlborough, Rough! Canterbury, Sinclair and Haast; Upper Waimakariri, T.F.C.; Otago, Lindsay, Buchanan! Petrie! Sea-level to over 2000ft. December–January.
6. L. lanata, A. Cunn. Precur. n. 437.—Root-fibres stout, fleshy, almost tuberous. Leaves numerous, all radical, densely tufted, 1–1½ in. long, oblong- or obovate-spathulate, obtuse or subacute, narrowed into a rather short broad petiole, coriaceous, coarsely and irregularly crenate-dentate, both surfaces hirsute or villous with copious soft hairs. Scapes 2–7 in. long, slender, wiry, erect, glabrous or nearly so, naked or with a few minute linear bracts. Heads ¼–⅓ in. diam.; involucral bracts linear, obtuse or subacute, glabrous, purple-tipped; margins scarious. Ray-florets numerous; ligules short, revolute. Achenes quite smooth, slightly falcate, compressed, narrowed at the base, suddenly contracted at the top into a short curved neck; margins thickened.—Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 126; Handb. N.Z. Fl. 137; Kirk, Students Fl. 258.
North Island: Dry clay hills from Mongonui southwards to the Auckland Isthmus; not common.
Easily distinguished by the hirsute leaves and glabrous scapes and achenes.
3. BRACHYCOME, Cass.
Small perennial herbs; either tufted with radical leaves and 1-headed scapes, or the stems branched, elongated, and clothed with alternate cauline leaves. Heads heterogamous, usually radiate. Involucre hemispherical or nearly so; bracts in about 2 series, with scarious margins. Receptacle convex or conical, naked. Ray-florets in one series, numerous, female, ligulate. Discflorets numerous, hermaphrodite, tubular, limb more or less dilated, 5-toothed. Anthers obtuse at the base. Style-branches of the disc-florets flattened, with lanceolate or triangular tips. Achenes compressed, with winged margins, or thick and obtusely 4-angled. Pappus a ring of short scale-like bristles or altogether wanting.
The genus has its headquarters in Australia, where there are nearly 40 species. In addition to those, and the five following found in New Zealand, there is one from tropical South Africa and another from Assam.

South Island: Canterbury Plains—Near Burnham, Kirk! between Springfield and the Kowai River, T. F. C. Stewart Island: Lyall (Handbook). December–January.
Although this has a very different appearance from the ordinary state of B. Sinclairii, some varieties of that plant approach it so closely as to be almost indistinguishable.
3. B. Sinclairii, Hook. f. Handb. N.Z. Fl. 137.—An exceedingly variable perennial herb 1–12 in. high, glabrous or more or less glandular-pubescent.

North Island: Mountainous districts from the East Cape southwards, but rare and local. South Island: Abundant in mountain districts throughout. 1000–6000 ft. December–February.
Very variable in the size and shape of the leaves, and in their being entire, toothed, or lobulate, or even pinnatifid; but the variations are not constant, and entire and lobulate leaves can often be found on the same plant. The heads also vary greatly in size.
4. B. odorata, Hook. f. Handb. N.Z. Fl. 138.—Rhizome stout, creeping, branched, ascending at the tips. Stems 2–4 in. long, erect or ascending, branched from the base, more or less pubescent or glandular, as are the leaves, scapes, and involucres.

A very variable plant, only separated from B. odorata by the much larger size and coarser habit and larger heads. It has the same strong fragrance.
4. OLEARIA, Mœnch.
Shrubs or trees. Leaves alternate, rarely opposite or fascicled, usually with white or buff tomentum beneath. Heads large or small, solitary or corymbose or paniculate, radiate or rarely discoid. Involucre broad or narrow; bracts imbricated in several rows, margins dry or scarious. Receptacle flat or convex, pitted. Florets few or many, rarely solitary; ray-florets female, in a single row, usually ligulate, spreading, rarely slender and filiform or altogether wanting; disc-florets hermaphrodite, tubular, 5-lobed. Anthers often acute at the base or with minute tails, rarely obtuse. Style-branches flattened, with short obtuse or rarely lanceolate appendages. Pappus of one or more rows of unequal scabrid bristles, often thickened at the tips. Achenes ribbed or striate, terete or slightly compressed.
In addition to the 35 species found in New Zealand, all of which are endemic, there are about 70 others, confined to Australia and Tasmania with the exception of 2 recorded from Lord Howe's Island. The genus is very closely allied to Aster, with which the late Baron von Mueller proposed to unite it, together with Celmisia and several other genera.

South Island: Marlborough, from Blenheim southwards to the Conway and Mason Rivers. Sea-level to 4000 ft. December–January.
A very handsome and remarkable plant, quite unlike any other species. It departs widely from the typical Olearias in the large broadly ovoid involucre with the bracts in very many series, and in the pappus of perfectly equal hairs.

A beautiful little plant, easily recognised by its small size, narrow leaves, slender peduncles, and purple flowers. I am indebted to Mr. Cockayne for a very interesting series of specimens showing the range of variation in the size and shape of the leaves. See his paper on "The Plant-covering of Chatham Island," Trans. N.Z. Inst, xxxiv. 288, for some remarks on the subject.

The Snares: Abundant, Kirk! Auckland Islands: Apparently rare, Lyall, Bolton, Kirk!
A magnificent plant, nearly related to O. Colensoi, but at once distinguished by the open and far more robust habit, larger and broader leaves, which are tomentose on the upper surface as well as beneath, and by the scales of the involucre being in several series.
9. O. Buchanani, T. Kirk, Students' Fl. 267.—An erect shrub or small tree; branchlets as thick as a goose-quill, reddish, glabrous. Leaves opposite, 2–4 in. long, elliptic-lanceolate, obtuse, gradually narrowed into a short petiole, quite entire, flat, glabrous above, clothed with thin appressed whitish tomentum beneath; veins finely reticulated above, obscure beneath.

Florets of the ray 3–4, ligulate; of the disc about 4, campanulate above. Achenes short, grooved, pubescent.
North Island: Buchanan! The exact locality not known.
Founded on a single specimen in Mr. Kirk's herbarium stated to have been collected by Mr. Buchanan in the year 1870 in some locality in the North Island. It is evidently a distinct species, not closely related to any other. It and O. Traversii are the only species found in New Zealand with large opposite leaves.
10. O. Traversii, Hook. f. Handb. N.Z. Fl. 731.—A small tree 15–30 ft. high, with a trunk 1–2 ft. diam.; bark pale, furrowed; branches tetragonous, clothed with appressed silky tomentum, as are the leaves beneath, branches of the inflorescence, and involucres.

North Island: Abundant from the North Cape to Hawke's Bay and Taranaki. Wharangipiro; Akepiro. November–February.
A very common plant to the north of the East Cape, varying greatly in the size, shape, and texture of the leaves, the size of the flower-heads, and the number of florets. Two forms may perhaps be distinguished, one with broad heads containing 8–12 florets, the other with much narrower heads and 4 to 8 florets. To this state Mr. Kirk gives the varietal name of angustata.
12. O. Allomii, T. Kirk in Trans. N.Z. Inst. iii. (1871) 179.—A dwarf sparingly branched shrub 1–3 ft. high; branches stout, and with the inflorescence and leaves beneath clothed with smooth and shining silvery tomentum. Leaves alternate, rather close-set, 1–2 in. long, ¾–1½ in. wide, oblong-ovate or elliptic-ovate, obtuse, truncate or rounded and often unequal at the base, shortly petiolate, excessively thick and coriaceous; veins reticulated above, midrib prominent below. Corymbs longer than the leaves, branched. Heads large, ½ in. diam., or even more when fully expanded; involucre broadly turbinate; scales laxly imbricate, tomentose, obtuse. Florets 15–20; rays about 8. Pappus-hairs unequal. Achenes grooved, hispid.—Students' Fl. 271.
North Island: Great Barrier Island, not uncommon, ascending to 2500 ft., Kirk! November–December.
Differs from O. furfuracea in the much smaller size, smaller close-set excessively rigid and coriaceous leaves, and especially in the much larger heads with twice the number of florets. I have a plant from Castle Hill, Coromandel, which resembles it in foliage, but forms a large shrub 12 ft. high. A similar form has been gathered by Petrie at Mercury Bay. But both of these have few-flowered heads only slightly larger than those of the typical state of O. furfuracea, and are best placed under that species.
13. O. nitida, Hook. f. Handb. N.Z. Fl. 125.—A much-branched shrub 3–12 ft. high, rarely more; branches stout or slender, often angular. Leaves alternate, variable in size, 1½–3½ in. long, broadly ovate or elliptic-ovate, acute or acuminate, rounded and often unequal at the base, coriaceous or almost membranous, clothed with appressed white and satiny tomentum beneath; margins distinctly or obscurely sinuate-dentate, rarely entire; petiole ½–1 in. long. Corymbs large, rounded, much-branched, very effuse; branches slender, silky-pubescent. Heads numerous, 16–14 in. long, obconic; scales of the involucre laxly imbricating; the outer ovate, pubescent or villous; the inner linear, fimbriate or sparingly silky. Florets 15–20; ray-florets 7–10, with a short broad ray. Pappus-hairs unequal, dirty-white or reddish. Achenes short, broad, silky.—Kirk, Students' Fl. 268. O. populifolia, Col. in Trans. N.Z. Inst. xvii. (1885) 243. O. suborbiculata, Col. l.c. xviii. (1886) 263. O. erythropappa, Col. l.c. xxii. (1890) 468. O. multiflora, Col. xxvii. (1895) 387. Eurybia nitida, Hook. f. Fl. Nov.

Shawia arborescens, Raoul, Choix, 45.
Var. cordatifolia, Kirk, Students' Fl. 268.—Leaves orbicular, cordate at the base, very coriaceous. Heads broadly obconic; involucral scales densely woolly, inner villous at the tips. Florets about 20; those of the ray with long and narrow ligules.
Var. angustifolia, Cheesem.—Leaves 2–3½ in. long, linear-lanceolate to lanceolate or oblong-lanceolate, almost membranous, margins sinuate. Corymbs lax, much-branched. Heads large, ⅓ in. long; rays long and narrow.
Var. capillaris, Kirk. l.c.—Small, stout or slender, densely or sparingly branched. Leaves small, ¼–1 in. long, ovate or rounded, membranous or subcoriaceous, silky above when young. Heads 3–12, in sparingly branched corymbs longer than the leaves; pedicels very slender; involucral scales glabrate or slightly villous. Florets 8–12.—O. capillaris, Buch. in Trans. N.Z. Inst. iii. (1871) 212.
North and South Islands, Stewart Island: Not uncommon from the East Cape and Taupo southwards. Sea-level to 4000 ft. November–January. Var. cordatifolia: Stewart Island, Kirk! Var. angustifolia: Ohinemuri Gorge, Thames Valley, T.F.C., Petrie! Var. capillaris: Mount Egmont, Adams and T.F.C.; Nelson mountains, H. H. Travers! Dall! source of the Poulter River (Canterbury), Cockayne!
Perhaps the most variable species of the genus, but generally to be recognised in all its forms by the thin white and peculiarly satiny tomentum on the under-surface of the leaves.
14. O. macrodonta, Baker in Gard. Chron. (1884) i. 604.—A shrub or small tree 5–20 ft. high, with a strong musky fragrance; branchlets clothed with closely appressed tomentum. Leaves alternate, 2–4 in. long, 1–1½ in. broad, ovate or ovate-oblong to narrow-oblong, acute or acuminate, rounded or rarely truncate at the base, rigid and coriaceous, silky above when young but becoming glabrous when mature, beneath clothed with closely appressed white tomentum; margins waved, coarsely and sharply toothed; veins at an obtuse angle to the midrib.

North Island: Wellington—Tararua Mountains and hills towards Wanganui, Buchanan.
I have seen no specimens of this, and the above description is adapted from Buchanan's. It is evidently near to O. lacunosa, but appears to have narrower leaves.
21. O. moschata, Hook. f. Handb. N.Z. Fl. 127.—A much-branched shrub 4–12 ft. high, with a strong musky fragrance; branches stout, spreading; branchlets, inflorescence, and leaves beneath clothed with soft white densely appressed tomentum. Leaves alternate, close-set, ⅓–¾ in. long, obovate-oblong, obtuse, narrowed into a very short petiole, quite entire, coriaceous, glabrous or slightly pubescent above, veins altogether concealed below; margins flat.

South Island: Canterbury—Ashburton Mountains, Potts! Upper Rangitata, Armstrong! Otago—Resolution Island and Preservation Inlet, Enys! 1500–3500 ft. January.
Only differs from O. Haastii in the more erect habit and longer and narrower leaves. Intermediate forms have been collected, but the usual aspect of the plant is distinct.
24. O. (?) coriacea, Kirk, Students' Fl. 276.—A sparingly-branched rigid shrub 6–8 ft. high; branches erect or ascending, rather stout, pubescent. Leaves alternate, ½–⅔ in. long, ovate or orbicular-ovate, obtuse, shortly petiolate, excessively thick and coriaceous, glabrous above, white with appressed tomentum beneath; margins recurved. Flowers not seen, but the peduncles of the previous year's inflorescence are about twice as long as the leaves, and are apparently branched at the top.
South Island: Marlborough—Awatere Valley and Mount Fyffe, Kirk!
Apparently a very distinct species, the exact position of which must remain doubtful until flowering specimens have been obtained.
25. O. nummularifolia, Hook. f. Handb. N.Z. Fl. 127.—A much and closely branched shrub 2–10 ft. high; branches stout, woody, scarred; younger ones often viscid, more or less clothed with whitish or yellowish stellate tomentum or almost glabrous.

Altitudinal range from 2000 ft. to 4500 ft., but descending to sea-level in Colac Bay, Southland. Var. cymbifolia: Mountain districts in the South Island, but local; most plentiful in Nelson and Marlborough.
A variable plant, especially in the size and shape of the leaves, the extent to which the leaf-margins are revolute, the size of the heads, and the number of florets. There is a specimen in Mr. Petrie's herbarium with the heads collected in 3–5-flowered corymbs.

Heads very numerous, small, 16–15 in. long, narrow; involucre cylindric; scales few, imbricate, glabrous or minutely pubescent. Florets 2 or 3, rarely 4; ray-florets 1 or rarely 2, sometimes wanting. Pappus-hairs in one series. Achenes silky.—Kirk, Forest Fl. t. 111; Students Fl. 274. Eurybia avicenniæfolia, Hook. f. Fl. Nov. Zel. i. 120. Shawia avicenniæfolia, Raoul, Choix, 19.
South Island, Stewart Island: Abundant throughout, ascending to 3000 ft. Akeake. January–February.
29. O. Forsteri, Hook. f. Handb. N.Z. Fl. 127.—A much-branched shrub or small tree 8–20 ft. high; branchlets grooved and angular, tomentose.

Zel. i. 119. Shawia paniculata, Forst. Char. Gen. 95, t. 48; A. Rich. Fl. Nouv. Zel. 243; A. Cunn. Precur. n. 434; Raoul, Choix, 18, t. 13; Kirk, Students' Fl. 217.
Var. elliptlca, Kirk, l.c.—Leaves narrower, linear-oblong or elliptic-oblong.
North and South Islands: From the East Cape southwards to Oamaru and Greymouth; often local, usually near the coast. Sea-level to 1500 ft. Akiraho. April–May.
The heads never contain more than one floret, which is invariably tubular and hermaphrodite. On account of the constancy of this character Mr. Kirk has proposed to revive Forster's genus Shawia, but, I think, quite unnecessarily. In O. avicenniæfolia the florets are sometimes reduced to 2, and occasionally there is no ray-floret, thus absolutely bridging over the gap between O. Forsteri and the remaining Oleariæ.

Involucre broadly campanulate; bracts in 3–4 series, linear-oblong, obtuse, dark-brown, viscid and glandular. Florets numerous, 20–35; ray-florets 8–18, short; corolla of disc-florets viscid and glandular. Achenes silky.—Kirk, Students' Fl. 275.
South Island: Mountain districts in Canterbury, Westland, and Otago; not uncommon. 1000–3000 ft. January–February.

6. CELMISIA, Cass.
Perennial herbs, usually tufted or with a short creeping rhizome, rarely with a procumbent or suberect branched stem. Leaves all radical and rosulate, or cauline and densely imbricated, narrowed into a sheathing base, usually clothed beneath with appressed white or buff tomentum. Scapes or peduncles long or short, rarely almost wanting, bracteate. Heads large, solitary, radiate. Involucre broadly hemispherical; bracts imbricated in several or many series, narrow, pubescent or cottony or glandular. Receptacle flat or convex, pitted. Ray-florets female, in a single row, ligulate; ligule spreading, flat or revolute, often long, always white. Discflorets numerous, hermaphrodite, tubular, 5-lobed. Anthers usually sagittate at the base, with short tails. Style-branches flattened, tipped with long or short appendages. Achenes linear, slightly compressed or angled, with 1—3 prominent ribs on each side. Pappus copious, of numerous unequal scabrid bristles.
The genus Celmisia, which is confined to New Zealand, with the exception of one species found in Australia and Tasmania, forms one of the chief ornaments of the montane and alpine flora of the colony, the various species usually composing a large proportion of the vegetation, especially in the South Island, where the mountain slopes and valleys are often whitened for miles from the abundance of their large daisy-like flowers. With few exceptions, the species are exceedingly variable and difficult of discrimination. This is especially the case with C. longifolia, coriacea, discolor, petiolata, and spectabilis, all of which run into forms which are easily distinguishable by the eye, and which to some extent may be permanent, but which it is almost impossible to define in precise language, and which in most cases are connected by numerous intermediates. As the flower-heads are very similar throughout the genus, except in size, the specific characters are almost wholly founded on the vegetative organs. The size, shape, and texture of the leaves, the nature of the tomentum clothing the under-surface, the differences in the leaf-sheaths, the length, stoutness, and indumentum of the scapes, and the peculiarities of the involucral bracts are all made use of. Of course, these are essentially variable characters, and can only be safely employed in combination. But in Celmisia, as in other large genera of the New Zealand flora, the species, such as they are, must be regarded as founded on an aggregation of several small prevalent characters rather than on conspicuous and important differences.

Fl. 131; Kirk, Students' Fl. 283. Erigeron novæ-zealandiæ, Buch. in Trans. N.Z. Inst. xvii. (1885) 287, t. 15.
South Island: Abundant in mountain districts throughout. Altitudinal range 2500 ft. to 5000 ft. December–February.
One of the most variable species of the genus. Large much-branched states approach C. Walkeri; short and broad-leaved forms come very near to C. incana; and states with large membranous leaves appear to pass directly into C. Sinclairii.
12. C. incana, Hook. f. Fl. Nov. Zel. i. 123, t. 34a.—Rhizome prostrate; branches short, stout, densely clothed with the old persistent leaves. Leaves numerous, crowded, 1–2½ in. long, ½–¾ in. broad, oblong-spathulate or obovate-spathulate, obtuse or subacute, coriaceous, entire or minutely serrulate, plaited or furrowed above, both surfaces or the lower alone thickly coated with lax snow-white soft tomentum; sheaths ½ as long as the blade, thin and membranous, grooved, glabrous or slightly cottony. Scapes 1–3, stout, 3–9 in. high, tomentose; bracts many, linear. Heads ¾–1½ in. diam.; involucral bracts subulate-lanceolate, acute or acuminate, glandular-pubescent and viscid; the outer often recurved. Rays numerous, spreading. Achene linear, silky, about equalling the pappus.—Handb. N.Z. Fl. 131; Kirk, Students Fl. 284. C. robusta. Buch. in Trans. N.Z. Inst. xix. (1887) 215, t. 18.
Var. petiolata. Kirk, l.c.—Smaller in all its parts. Leaves with an oblong blade suddenly narrowed into a distinct petiole at the top of the expanded sheath, often quite glabrous above, the tomentum of the under-surface more silvery and appressed. Heads smaller, ½–¾ in. diam.
North Island: Summit of Moehau (Cape Colville), Adams! Mount Hikurangi, Colenso, Adams and Petrie! Ruahine Mountains, Colenso! Tararua Mountains, Buchanan. South Island: Not uncommon on the mountains as far south as Canterbury and the west of Otago. 2500–5000 ft. December–January.
The typical state, with large broad plaited leaves clothed on both surfaces with snow-white tomentum, has a very distinct appearance; but small forms, with smaller and narrower leaves almost glabrous above, are difficult to separate from C. discolor.
13. C. Haastii, Hook. f. Handb. N.Z. Fl. 131.—Forming large patches. Rhizome creeping, putting up short erect branches. Leaves greenish-grey, 1½–3in. long, ½–1 in. wide, broadly oblong to oblong-spathulate or narrow obovate-spathulate, obtuse or acute, narrowed towards the base, subcoriaceous, glabrous and usually longitudinally plaited above, beneath clothed with thin whitish tomentum; margins recurved, minutely denticulate; sheaths ⅓–½ as long as the blade, thin, membranous, glabrous. Scapes usually several, 2–6 in. long, stout, densely tomentose or almost glabrous; bracts many, linear, acute or rarely obtuse, tomentose. Heads 1–1½ in. diam.; involucral bracts linear, acute or acuminate, membranous, softly tomentose or almost villous. Rays spreading. Achene linear, glabrous, longer than the pappus.—Kirk, Students' Fl. 284.
South Island: Not uncommon in the central and western portions of the Southern Alps, from the Spencer Mountains southwards. 3000–6000 ft. December–February.
Well marked by the greenish-grey foliage, stout usually tomentose scapes with numerous linear bracts, membranous involucral bracts, and glabrous achene.
14. C. Lindsayi, Hook. f. Handb. N.Z. Fl. 132.—Often forming large rounded masses. Stems stout, woody, prostrate; branches numerous, decumbent or suberect. Leaves numerous, crowded, 3–8 in. long, ½–1 in. broad, linear-oblong or lanceolate, obtuse or subacute, coriaceous, obscurely and remotely denticulate or quite entire, glabrous above, clothed with appressed white tomentum beneath, midrib evident; sheaths broad, glabrous, deeply grooved. Scapes usually numerous, 2–8 in. long, slender, flexuous, glabrous or pubescent above; bracts linear. Heads 1–2 in. diam.; involucral bracts linear, acuminate, glabrate or pubescent. Ray-florets 30–40, spreading, rather distant. Tube of the disc-florets somewhat thickened; anther-cells obtuse at the base. Achene linear, silky.—Lindsay, Contrib. N.Z. Bot. 53, t. 3, f. 1; Bot. Mag. t. 7134; Kirk, Students' Fl. 284. Erigeron Bonplandii, Buch. in Trans. N.Z. Inst. xix. (1887) 213.
South Island: Otago—Cliffs of the southeast coast, from the Clutha River to Waikawa, Lindsay, Buchanan! Petrie! Kirk! Mount Bonpland, Martin; Lake Harris, H. J. Matthews. January–February.
A handsome species, which succeeds well in cultivation. Mr. Kirk considers that the Mount Bonpland and Lake Harris localities are erroneous.
15. C. Sinclairii, Hook. f. Handb. N.Z. Fl. 132.—Stems branched at the base, prostrate; branches suberect. Leaves 1–3 in. long or more, ¼–¾ in. broad, linear-obovate or obovate-spathulate to linear-oblong, obtuse or subacute, membranous or rarely coriaceous, obscurely toothed, glabrous above, beneath clothed with thin white appressed tomentum or rarely glabrous on both surfaces; midrib evident; sheaths membranous, glabrous or slightly cottony. Scapes 1 or more, slender, 3–9 in. high; bracts linear, white beneath. Heads 1–1½ in. diam.; involucral bracts linearsubulate, pubescent and viscid; tips recurved. Ray-florets spreading. Achene silky.—Kirk, Students' Fl. 285.
South Island: Not uncommon throughout in mountain districts. Stewart Island: Summit of Mount Anglem, Kirk! Altitudinal range 2500–5000 ft. December–January.
This comes very close to large forms of C. discolor, being only separable by the larger and much more membranous leaves, which are dull-green above and clothed with thin tomentum beneath.
16. C. Traversii, Hook. f. Handb. N.Z. Fl. 134.—Root stout, tapering. Leaves 6–16 in. long including the petiole, 1½–2½ in. broad, oblong or oblong-lanceolate, subacute or obtuse, coriaceous, dark brownish-green and glabrous above except the silky midrib, under-surface and margins clothed with rich soft and thick velvety ferruginous tomentum; midrib beneath glabrous, dark-purple; petiole from one-half to as long as the blade, purple; upper surface and sheaths with loose snow-white tomentum. Scapes stout, 8–20 in. long, densely clothed with ferruginous tomentum; bracts few or many, linear. Heads 1–2 in. diam.; bracts of the involucre numerous, linear, clothed with ferruginous wool. Rays narrow, spreading. Achene glabrous.—Kirk, Students' Fl. 285.
South Island: Nelson—Mount Arthur, Mount Peel, Raglan Mountains, T.F.C.; Discovery Peaks, Travers! mountains overlooking the Hanmer Plains and Upper Clarence Valley, T.F.C.; Mount Captain and the Upper Waiau, Kirk! 3500–5500 ft. December–January.
A magnificent species, remarkable for the bright ferruginous tomentum of the under-surface of the leaves, the purple midrib, and the snow-white tomentum of the sheaths. I have not seen specimens from the south of Lake Tennyson.
17. C. cordatifolia, Buch. in Trans. N.Z. Inst. xi. (1879) 427, t. 18.—Leaves 2–9 in. long including the petiole, ½–2 in. broad; blade about half the length, ovate-oblong or oblong, obtuse or subacute, cordate at the base, coriaceous, entire, dull-green and glabrous above, plaited, beneath clothed with velvety ferruginous tomentum; petiole grooved, expanded into a broad sheath at the base, villous with brownish tomentum or almost glabrous, sometimes purplish. Scape 6–12 in. long, stout, clothed with ferruginous tomentum; bracts numerous, linear. Heads 1½–2 in. diam.; involucral bracts numerous, villous or almost glabrous. Rays narrow, ¾ in. long. Achene linear, glabrous, strongly ribbed, exceeding the pappus.—C. petiolata var. cordatifolia, Kirk, Students' Fl. 286.
South Island: Nelson—Mount Starveall, A. McKay! Bryant! Mount Duppa, Mount Richmond, MacMahon! January.
In the "Students' Flora" Mr. Kirk has reduced this to C. petiolata, but it differs from all the forms of that species in the broader coriaceous leaves cordate at the base, and in the dark ferruginous tomentum. In the texture of the leaves and their tomentum it approaches C. Traversii, but differs entirely in the cordate leaf-base, and in the petioles wanting the snow-white tomentum which is so characteristic a feature of that plant.
18. C. petiolata, Hook. f. Handb. N.Z. Fl. 134.—Leaves 4–14 in. long including the petiole, ¾–2 in. wide; blade about half the length, oblong to linear-oblong or oblong-lanceolate, subacute, membranous or coriaceous, entire, glabrous or silky above, beneath clothed with whitish appressed tomentum; midrib usually glabrous, purple, veins diverging; petiole purplish, grooved, more or less loosely tomentose, expanded at the base into a short sheath. Scapes usually several, 6–18 in. long, often purplish, tomentose or villous; bracts linear. Heads 1½–2½ in. diam.; involucral bracts linear-subulate, usually densely tomentose. Eay-florets numerous, with a ligule ½–¾ in. long. Achene glabrous or nearly so, strongly ribbed.—Kirk, Students' Fl. 286.
Var. rigida, Kirk, l.c.—Leaves oblong-lanceolate or ovate-lanceolate, coriaceous, rigid, tomentum of under-surface white or ferruginous. Head rather larger, the rays sometimes 1 in. long.
Var. membranacea, Kirk, l.c.—Leaves narrowed at both ends, acute, membranous, glabrous on both surfaces or nearly so. Scape glabrate or pubescent. Heads rather smaller, involucral bracts glabrate.
South Island: Not uncommon in the central and western portions of the Southern Alps, from Lake Tennyson southwards to the west of Otago. Var. rigida: Stewart Island, Kirk! Var. membranacea: Clarence and Waiau Valleys, Travers! Kirk! Lyell Mountains, Townson! 2000–4500 ft. Deember–January.
Best distinguished by the almost membranous narrow-oblong leaves, with purple midribs and long and slender purple petioles.
19. C. Rutlandii, T. Kirk in Trans. N.Z. Inst. xxvii. (1895) 329.—Leaves 3–12 in. long including the petiole, l–2½ in. broad, oblong or oblong-lanceolate, acute or apiculate, narrowed into the petiole, coriaceous, glabrous above or the midrib slightly cottony, beneath clothed with appressed white satiny tomentum; margins entire or minutely denticulate, often revolute; petiole shorter than the blade or equalling it, broad, grooved, densely clothed with loose snow-white tomentum. Scapes several, exceeding the leaves, softly cottony; bracts narrow-linear, purplish, tomentose. Heads 1–1¾ in. diam.; involucral bracts linear, acuminate, erect, glabrate or the outer cottony. Ray-florets numerous. Achenes silky, strongly grooved.—Students' Fl. 286.
South Island: Marlborough—Mount Stokes, Kirk! MacMahon! December–January.
A handsome and distinct species, allied to C. petiolata, but differing in the loose snow-white tomentum of the sheaths, the satiny under-surface of the leaves, and the thin erect almost glabrous involucral bracts.
20. C. spectabilis, Hook. f. Fl. Antarct. i. 35.—Often forming large patches. Stems stout, with the leaf-sheaths 1–2 in. diam. Leaves very numerous, crowded, rosulate; blade 3–6 in. long, ¼–¾ in. broad, narrow linear-oblong, acute or obtuse, slightly narrowed towards the base, very thick and coriaceous, glabrous or with a thin pellicle of silvery hairs above, longitudinally furrowed, beneath clothed with densely matted pale - buff or white woolly tomentum; margins recurved, entire or minutely serrulate; sheaths usually equalling the blade, inembranous, clothed on both surfaces with loose soft and silky snow-white tomentum. Scapes 1 or several, stout, much longer than the leaves, densely cottony; bracts numerous, linear. Heads about 1½ in. diam.; involucral bracts narrow linear-subulate, woolly or rarely almost glabrate, outer recurved at the tips. Rays numerous, rather short. Achene glabrous.—Fl. Nov. Zel. i. 122, t. 33; Handb. N.Z. Fl. 134; Kirk, Students' Fl. 287. C. ruahinensis, Col. in Trans. N.Z. Inst. xxvii. (1895) 388. C. mollis, Cockayne, l.c. xxxi. (1899) 423.
North Island: Mountains of the interior, from Mount Hikurangi and Lake Taupo southwards. South Island: Abundant in mountain districts in Nelson, Canterbury, and Westland; rare in Otago. 500–4500 ft. Puhaeretaiko. December–February.
Well marked by the short narrow rigid leaves, densely clothed beneath with pale-buff soft and matted not appressed woolly tomentum. Mr. Cockayne's C. mollis is a state with the tomentum not nearly so woolly, the hairs being straighter and more silky.
21. C. dubia, Cheesem. n. sp.—Forming large patches. Stems rather stout, ¼–½ in. diam. with the leaves on. Leaves 1½–3in. long, ⅓–⅔ in. broad; blade oblong or linear-oblong or lanceolate, acute at both ends, coriaceous, glabrous and furrowed above, clothed with soft white tomentum beneath, midrib distinct beneath; margins usually recurved, entire or very obscurely serrulate; petiole equalling the blade or shorter than it, slender, expanded below into a broad membranous sheath. Scapes 1 or more, 3–8 in. long, rather slender, white with loose cottony tomentum; bracts 4–6, linear or linear-spathulate. Heads about ¾ in. diam.; involucral bracts numerous, linear or linear-lanceolate, acute, scarious, shining, sparingly cottony or almost glabrate. Rays numerous, spreading. Achene glabrous.
South Island: Nelson—Mount Rochfort, Mount Frederic, and other localities near Westport, Townson! 2000–3000 ft. January–March.
A puzzling plant, which seems nearer to C. spectabilis than to any other species, although very different in appearance. In some respects it approaches C. parva, which, however, is a much smaller and more slender plant, with an almost filiform and nearly glabrous scape, and with much smaller heads and hispid achenes.
22. C. verbascifolia, Hook. f. Fl. Nov. Zel. i. 121.—A large handsome species. Root stout, as thick as the thumb. Leaves 8–20 in. long or more including the petiole, 1½–3in. broad, lanceolate to oblong-lanceolate or spathulate-lanceolate, acute, narrowed into the petiole, coriaceous, glabrous or slightly cottony above but with woolly margins, beneath clothed with soft white or buff tomentum, entire or very obscurely serrulate; petiole as long as the blade, narrow, broader and sheathing at the base, grooved, densely woolly or almost glabrous. Scapes longer than the leaves, densely woolly; bracts numerous, linear or linear-spathulate, tomentose, the lowest sometimes 4 in. long. Heads about 4 in. diam.; involucral bracts narrow-linear, densely and softly woolly. Ray-florets slender; tube of corolla of disc-florets thickened below. Achene linear, glabrous, hardly equalling the pappus.—Handb. N.Z. Fl. 132; Kirk, Students' Fl. 285.
South Island: Otago—Milford Sound and Port Preservation, Lyall (Handbook); Waitaki Valley, Horse Ranges, Flag Swamp, Macrae's, Petrie! Kirk! Sea-level to 2000 ft. December–February.
I have seen no specimens from the localities where the species was originally discovered by Lyall, and it is quite possible that the plant from the Waitaki Valley, &c., on which the above description is founded, may not be the same. It has been reported from Campbell Island, but I think erroneously.
23. C. Brownii, F. R. Chapm. in Trans. N.Z. Inst. xxii. (1890) 444.—Leaves 6–10 in. long including the petiole, 1–2 in. broad, lanceolate or oblong-lanceolate, acute, gradually narrowed into the petiole, coriaceous, quite entire or very obscurely denticulate, glabrous or sparingly pubescent above, beneath clothed with rather thin white or greyish-white tomentum; petiole shorter than the blade, tomentose. Scapes 6–14 in. long or more, tomentose; bracts linear, obtuse, almost villous. Heads 1–2 in. diam.; involucral bracts linear-subulate, villous towards the tips. Rays numerous, narrow, spreading. Achene sparingly silky.—Kirk, Students' Fl. 286.
South Island: Otago—Mystery Pass, between Lake Manapouri and Smith Sound, Chapman; Clinton Valley, Lake Te Anau, Petrie!
Of this I have only seen a single leaf from Mr. Chapman's type, and a specimen of what appears to be the same collected by Mr. Petrie in the Clinton Valley. Further material is required to prepare a satisfactory description. It appears to differ from C. verbascifolia in the smaller size, thinner and more appressed tomentum, and much less woolly scapes, bracts, and involucres. A plant gathered by Mr. Cockayne on the Humboldt Mountains seems to be intermediate between the two species.
24. C. Mackaui, Raoul, Choix Pl. Nouv. Zel. 19, t. 14.—Leaves 6–20 in. long, 2–4 in. broad, linear-lanceolate, acuminate, gradually narrowed to the base, quite entire, membranous, glabrous on both surfaces when mature or slightly cottony at the base, often rather glaucous beneath; petiole broad, grooved, sheathing at the base, usually cottony on the inner surface. Scapes 12–24 in. high, stout, glabrous or sparingly cottony; bracts numerous, lanceolate, acuminate, sheathing at the base. Heads about 2 in. diam.; involucral bracts numerous, ovate-lanceolate, acuminate, membranous, glabrous. Rays long and narrow. Disc-florets very numerous; corolla thickened at the base. Achene linear, glabrous, strongly ribbed.—Hook. f. Fl. Nov. Zel. i. 122; Handb. N.Z. Fl. 133; Kirk, Students' Fl. 287. C. coriacea, Raoul, Ann. Sci. Nat. 1844, 119 (non Hook. f.).
South Island: Marlborough—Mount Fyffe, H. B. Kirk (leaves only). Canterbury—Rocky places near Akaroa, Raoul; Mount Herbert, W. Gray! January–February.
A very distinct species, remarkable for the long acuminate leaves green and glabrous on both surfaces, the large heads, and herbaceous acuminate involucral bracts.
25. C. coriacea, Hook. f. Fl. Antarct. i. 36.—Leaves 8–24 in. long or more, ¾–3 in. broad, lanceolate or linear-lanceolate or linear-oblong, acute, narrowed towards the base, coriaceous, upper surface longitudinally furrowed or almost plicate and covered with a delicate silvery pellicle, beneath clothed with appressed white and silvery tomentum; margins entire or very obscurely serrulate; sheaths short, broad, grooved, densely clothed with soft cottony or woolly tomentum. Scapes stout, 1–3 ft. high, densely woolly or cottony; bracts numerous, linear, erect, cottony. Head 1½–3 in. diara. or more; involucral bracts numerous, linear-subulate, cottony or almost glabrate. Rays very numerous, spreading, 1½ in. long; tube of corolla more or less pubescent. Achene linear, compressed, grooved, pubescent.—Fl. Nov. Zel. i. 121, t. 32; Handb. N.Z. Fl. 132; Kirk, Students' Fl. 287. C. Martini, Buch, in Trans. N.Z. Inst. xix. (1887) 213. C. flaccida, Cockayne in Trans. N.Z. Inst. xxxi. (1899) 422. Aster coriaceus, Forst. Prodr. n. 297; A. Rich. Fl. Nouv. Zel. 250; A. Cunn. Precur. n. 439.
North Island: Tararua Mountains, Buchanan. South Island: Abundant in mountain districts. Altitudinal range 1500–4500 ft. Cotton-plant; Leather-plant. December–February.
A truly noble plant, probably the finest species of the genus. In its most luxuriant state it has a short stout stem which with the old leaf-sheaths is sometimes as thick as the wrist, and is crowned with numerous spreading and erect lanceolate leaves, from among which arise one or several stout scapes, bearing heads sometimes more than 3 in. diam., with long and narrow rays. This passes by almost imperceptible gradations into smaller varieties with narrower often less coriaceous leaves and smaller heads, with shorter and proportionately broader rays. It is difficult to find distinguishing characters between some of these forms and C. Monroi and other species. In cultivation it varies still more largely, and often produces branched scapes, a peculiarity quite unknown in any Celmisia in the wild state, so far as my own observations go. Some of the cultivated races appear to be permanent, and Mr. Kirk has briefly characterized the following in his "Students' Flora": (1) foliosa, with crowded foliaceous bracts sometimes 6 in. long; (2) corymbifera, with branched scapes, the heads forming an open corymb; and (3) ensata, which has ensiform leaves 8–12 in. long and ½ in. wide, and an irregularly branched scape. Mr. H. J. Matthews informs me that the last form, which has a very distinct appearance, occurs in a wild condition near Lake Harris, Otago, but I have only seen cultivated specimens.
26. C. Armstrongii, Petrie in Trans. N.Z. Inst. xxvi. (1894) 269.—Stems short, stout, with the leaf-sheaths sometimes as thick as the wrist, crowned with numerous radiating leaves. Leaves 6–18 in. long or more, ¼–¾ in. broad, linear-ensiform, gradually tapering from below the middle to the acute apex, slightly narrowed below, rigidly coriaceous, upper surface longitudmally ribbed and covered with a delicate silvery pellicle, beneath clothed with smooth and satiny appressed tomentum, except the very stout and prominent midrib; margins recurved when dry; sheaths long, broader than the blade, clothed with snow-white cottony tomentum. Scapes usually several, as long as or longer than the leaves, rather slender, white and cottony; bracts numerous, linear. Head 1–1½ in. diam.; invoiucral bracts linear-subulate, rather rigid, glabrous or cottony on the margins, tips recurved. Rays narrow. Achene linear, grooved, pubescent.—Kirk, Students' Fl. 290.
South Island: Nelson—Heaphy River, Dall! mountains near Westport, Townson! Westland—Arthur's Pass, Armstrong! Kirk! Cockayne! T.F.C.; Kelly's Hill, Petrie! 2500–4500 ft. December–January.
Distinguished from C. Lyallii by the broader perfectly straight leaves with a stout midrib and satiny appressed tomentum. From C. Monroi it is-separated by the more rigid ribbed and pointed leaves and almost glabrous heads.
27. C. Petriei, Cheesem. n. sp.—Apparently a stout tufted plant. Leaves 8–18 in. long or more, ½–¾ in. broad, dagger-shaped, narrowed into an acuminate rigid and almost pungent point, contracted just above the top of the sheath, strict, erect, rigidly coriaceous, above perfectly glabrous and when dry marked with a stout longitudinal ridge or plait on each side of the middle of the leaf, beneath clothed with silvery-white appressed satiny tomentum and with two grooves answering to the ridges of the upper surface; midrib not evident on either surface; margins conspicuously recurved towards the tip of the leaf, less so or almost flat elsewhere; sheaths 1½–3 in. long, broader than the blade, deeply grooved, more or less covered with thin cottony tomentum. Scape 12–18 in. long, stout, densely cottony; bracts numerous, narrow-linear, the lower often 2–3 in. long. Head 1½ in. diam. or more; involucral bracts subulate-lanceolate, acuminate, chaffy and rather rigid, glabrate or the outer somewhat cottony, often recurved. Achene hispid.
South Island: Otago—Clinton Saddle, Lake Te Anau, Petrie! Humboldt Mountains, H. J. Matthews!
A remarkable plant, of which I have seen only very imperfect specimens. The straight dagger-shaped leaves, with their two longitudinal plaits and rigid acuminate points, are quite unlike those of any other species.
28. C. Lyallii, Hook. f. Handb. N.Z. Fl. 133.—Stem short, stout, crowned with a dense tuft of crowded radiating leaves. Leaves 9–18 in. long or more, ¼–⅓ in. broad, narrow-ensiform, straight or slightly curved, gradually tapering from the base to the rigid almost pungent tip, rigidly coriaceous, glabrous and smooth and even above, beneath strongly grooved and clothed with thin appressed tomentum or almost glabrous; margins quite entire; sheaths broader than the blade, thin, grooved, clothed with snowwhite tomentum. Scapes 1 or several, longer or shorter than the leaves, rather slender, white with cottony tomentum; bracts linear. Head 1–2 in. diam.; involucral bracts subulate-lanceolate, rigid, glabrate or the margins cottony, tips recurved. Rays rather short, narrow. Achene linear, hispidulous, longer than the pappus.—Kirk, Students' Fl. 290.
Var. pseudo-Lyallii.—Leaves not so rigid, grooved and plaited above, beneath clothed with thick soft tomentum, which usually conceals both veins and midrib. Heads more cottony. Achene nearly glabrous.
South Island: Common in mountainous districts throughout. 1000–4500 ft. December–January.
One of the most distinct species of the genus, easily recognised by the narrow tapering rigid leaves, with almost pungent tips.
29. C. viscosa, Hook. f. Handb. N.Z. Fl. 133.—More or less viscid in all its parts. Stem branched; branches short, stout, with the old sheaths 1–1½ in. diam. Leaves numerous, crowded, erect, 3–5 in. long, ¼ in. broad, linear, obtuse or acute, viscid, very thick and coriaceous, rigid, longitudinally grooved on both surfaces, glabrous or hoary above, beneath white or grey with appressed tomentum; sheaths about 1 in. long, broader than the blade, glabrous, brown. Scapes usually several, much longer than the leaves, 6–12 in. long, stout, pubescent and viscid; bracts numerous, linear. Head 1½ in. diam.; involucral bracts numerous, linearsubulate, densely woolly and tomentose, viscid. Rays short, spreading. Achene linear, silky.—Kirk, Students' Fl. 290.
South Island: Not uncommon in alpine localities from the Wairau Valley southwards. 4000—6500 ft. January.
A very distinct plant, well marked by the short and narrow erect grooved and viscid leaves, with glabrous sheaths.
30. C. Monroi, Hook. f. Handb. N.Z. Fl. 133.—Leaves 3–12 in. long, ⅓–¾ in. broad, narrow linear-oblong or linear-lanceolate, acute or subacute, strict, coriaceous, longitudinally grooved or plaited above and covered with a delicate pellicle of silvery hairs, beneath clothed with appressed white tomentum, often wrinkled in parallel lines when dry; margins recurved; sheaths short, densely clothed with snow-white tomentum. Scapes 1 or several, 8–16 in. long, stout, woolly and cottony; bracts numerous, linear. Head 1–2 in. diam.; involucral bracts numerous, linear-subulate, usually more or less woolly and cottony. Rays numerous, ½–¾ in. long; tube of corolla glabrous. Achene hispidulous.—Bot. Mag. t. 7496; Kirk, Students' Fl. 288.
South Island: Marlborough—Upton Downs, Awatere, Monro! Canterbury—Mount Cook district, Haast, T.F.C.; Hopkins River, Haast. 1500–4500 ft. December–January.
The above description is based upon one of Monro's original specimens from the Upton Downs, now in Mr. Petrie's herbarium, and on others which almost exactly match it collected by myself in the Mount Cook district. Most of the specimens referred to C. Monroi in New Zealand collections are nothing more than small forms of C. coriacea; but it may be distinguished from all such by the narrower and more rigid leaves, which are usually conspicuously furrowed on both surfaces, and by the smaller heads with shorter broader rays, and by the glabrous corolla-tube. The plant figured in the "Botanical Magazine" has broader softer leaves than Monro's specimen.
31. C. Adamsii, Kirk in Trans. N.Z. Inst. xxvii. (1895) 329.—Leaves 6–18 in. long including the sheaths, ½–1 in. broad, narrow linear-oblong or linear-lanceolate, acute or obtuse, narrowed into an evident petiole at the top of the sheath, membranous, glabrous above, beneath clothed with soft white tomentum except the evident midrib; margins minutely denticulate, flat or slightly recurved; sheaths thin and membranous, grooved, sparingly cottony or almost glabrous. Scapes equalling or exceeding the leaves, slender, sometimes flexuose, thinly clothed with cottony tomentum; bracts short, linear. Head 1–1½ in. diam.; involucral bracts subulate-lanceolate, acute, glabrous or cottony. Rays few, spreading. Achene glabrous.—Kirk, Students' Fl. 288.
Var. rugulosa, Cheesem.—Shorter and stouter. Leaves more coriaceous, wrinkled above; sheaths more cottony. Scapes stouter, densely cottony.
North Island: Auckland—Castle Rock, Coromandel, T.F.C.; Table Mountain (Whakairi) and other hills between the Thames and Tairua, Adams! T.F.C. Var. rugulosa: Mount Manaia and hills to the north of Whangarei Harbour, Kirk! T.F.C. December–January.
Most nearly allied to C. longifolia, from which it is separated by the broader and flatter membranous leaves. Mr. Kirk placed my variety rugulosa under C. Monroi, from which it differs markedly in the much less rigid habit, spreading thinner leaves, shorter cauline bracts, nearly glabrous involucre, and fewer rays. It is much nearer to C. Adamsii.

North and South Islands, Stewart Island: From the Bay of Islands and the Great Barrier Island southwards, tiut rare and local to the north of the Upper Thames and Waikato. Sea-level to nearly 6000 ft. November–January.
The most widely distributed and variable species of the genus, found in all soils and situations. It is the only species that extends beyond the colony, being not uncommon in the Australian Alps and in Tasmania. The varieties characterized above are merely prevalent forms, and are connected by numerous intermediates.
33. C. linearis, Armstr. in Trans. N.Z. Inst. xiii. (1881) 337.—Stems branched at the base; branches short, stout.

Most of the Stewart Island specimens have longer and narrower leaves, with much more revolute margins, the tomentum is thinner and more appressed, and the scape is longer. Those from Mount Arthur have flatter leaves tapering from the base, the tomentum is buff-coloured and much looser, and the scape is shorter and densely woolly. It is possible that more species than one are included under the description, but the material is not sufficient to prove this.
34. C. laricifolia, Hook. f. Fl. Nov. Zel. ii. 331.—Stems prostrate or decumbent, much-branched at the base; branches 1–3 in. long, densely leafy. Leaves numerous, crowded, erect or recurved, ⅓–1 m. long, 120 in. broad, very narrow-linear or acerose, pungent, glabrous or slightly silky above, clothed with silvery tomentum beneath; margins strongly recurved; sheaths much broader than the blade, membranous, cottony or almost glabrous. Scape 2–4 in. long, very slender, glabrate or cottony; bracts few, very small. Head ½ in. diam.; involucral bracts few, erect, linear-subulate, cottony. Rays few, short. Achene hispid.—Handb. N.Z.

Achene silky.—Kirk, Students' Fl. 291.
North Island: Tararua Range, Budden. South Island: Canerbury—Mount Brewster, Haast; Mount Cook district, Dixon! T.F.C. Otago—Mount Alta, Hector and Buchanan! Hector Mountains, Humboldt Mountains, Mount Tyndall, the Remarkables, Petrie! Mount Earnslaw, H. J. Matthews. 4500–6500 ft. January–February.
Apparently a very distinct species, at once recognised by the small densely imbricated linear-obovate leaves and rather large heads.
36. C. Macmahoni, T. Kirk in Trans. N.Z. Inst. xxvii. (1895) 327.—Tufted, forming small patches. Leaves numerous, crowded, rosulate, 1–1½ in. long including the sheath, linear-oblong, acute or subacute, thick and coriaceous, densely clothed on both surfaceswith long white or buff silky hairs, 5–7-nerved beneath, margins flat; sheaths short, about as broad as the blade, glabrous above, with silky hairs beneath.

One of the most distinct species of the genus, often forming extensive carpets in open places on the mountains, easily recognised from a distance by the peculiar greenish-grey colour. Mr. Kirk's var. pedunculata is only a form in which the peduncle elongates after flowering.
39. C. argentea, T. Kirk, Students' Fl. 292.—Habit of C. sessiliflora, but more slender and much more branched; branches longer, 2–5 in., erect, ¼–½ in. diam. Leaves numerous, crowded, densely imbricated, ¼–½ in. long including the sheath, 130 in. wide, linear-subulate, acute or subacute, coriaceous, flat or concave above, rounded on the back; sheaths longer and much broader than the blade, membranous, clothed with long silky hairs on the margins and back but often nearly glabrous in front.

42. C. vernicosa, Hook. f. Fl. Antarct. i. 34, t. 26, 27.—Perfectly glabrous, leafy, densely tufted. Leaves very numerous, most densely crowded, rosulate, spreading, 1–4 in. long, 18–13 in. broad, linear, straight or curved, obtuse or subacute, in small specimens often knobbed at the tip, rigid and coriaceous, polished and shining, entire or obscurely toothed, flat or convex above, margins recurved, midrib prominent beneath; sheath short, broad.

Auckland and Campbell Islands: Abundant from sea-level to over 1200 ft. November–December.
An exceedingly handsome plant, of which a beautiful plate is given in the "Flora Antarctica." It and the following species are the only ones with purple disc-florets.
43. C. Campbellensis, Chapm. in Trans. N.Z. Inst. xxiii. (1891) 407.—Leaves rosulate, 3–6 in. long, ½–¾ in. broad, lanceolate or obovate-lanceolate, obtuse or subacute, gradually narrowed to a short broad sheathing base, hardly coriaceous, glabrous above and longitudinally furrowed, sparingly tomentose and with prominent longitudinal ribs beneath; margins flat, finely and sharply serrate.

The flower-heads closely resemble those of C. vernicosa, but the leaves are altogether different. I have only seen one poor specimen. Mr. Chapman's name has one month's priority of publication over Mr. Kirk's.
7. VITTADINIA, A. Rich.
Branched perennial herbs or small undershrubs, usually woody at the base. Leaves alternate, entire or toothed or lobed.

Achene linear, compressed, obtuse at the tip, narrowed to the base, pubescent, usually with 5–8 striæ on each face. Pappus exceeding the achene.—A. Cunn. Precur. n. 441; Raoul, Choix, 45; Hook. f. Handb. N.Z. Fl. 136; Benth. Fl. Austral. iii. 490; Kirk, Students Fl. 294. Eurybiopsis australis, Hook. f. Fl. Nov. Zel. i. 125.
North and South Islands: From the Great Barrier Island and Whangarei southwards, but local to the north of the East Cape. Sea-level to 3000 ft. November–January.
Also found in Australia and Tasmania, where it runs into numerous varieties, some of which differ widely from the type, and may prove to be distinct species. Of these var. dissecta (Benth. Fl. Austral, iii. 491) has become naturalised near Nelson. It can be distinguished by the leaves being pinnatifid, with the segments again lobed, and by the purple ray-florets. Two other closely allied forms (var. linearis var. erecta, Kirk, "Students' Flora," 295), with linear or linear-spathulate leaves ¾–1½ in. long and purple rays, have established themselves in the interior of Otago and elsewhere in the South Island.

Marlborough—Mount Mouatt, Awatere, Sinclair, Kirk! Kaikoura Mountains, Buchanan ! 4000–6500 ft. Vegetable sheep. December–January.
One of the most remarkable plants known. The branches are everywhere covered and altogether concealed by the densely imbricated woolly leaves, and are so closely compacted that it is impossible to thrust the finger in between. In fact, the whole plant has the appearance of a woolly cushion marked with mamillated projections corresponding to the tips of the branches. The flower heads are sunk in the top of these projections, and are almost hidden by the woolly hairs of the leaves. For a detailed account of the vegetative organs of the plant, and its minute anatomy, reference should be made to a paper by Miss E. Low in the Trans. N.Z. Inst, xxxii. 150.
2. H. recurva, Hook. f. Handb. N.Z. Fl. 156.—Forming laxly branched masses 3–9 in. broad, everywhere covered with soft dense fulvous or rufous wool; branches spreading, open, with the leaves ½–¾ in. diam. Leaves laxly imbricating, ½–¾ in. long, obovate or obovate-spathulate, sharply recurved about the middle; the lower half loosely sheathing the branch, thin and membranous, veined, clothed with long woolly hairs; the upper half thicker, with the superior surface much puckered and wrinkled, with corresponding reticulations beneath, both surfaces covered with densely compacted wool.

South Island: Not uncommon on dry shingle slopes in alpine localities from Nelson to the west of Otago. 4000–6500 ft. December–January.
Allied to the preceding, but distinguishable by the less-branched habit, paler wool, flat leaves, and larger heads.
4. H. Greenii, Hook. f. ex T. Kirk Students' Fl. 296.—"Densely tufted, about 2 in. high; stems with the leaves ⅓ in. diam. Leaves densely imbricating all round the stem, ⅕ in. long, obovate-cuneate, rounded at the tip, thickly clothed on both surfaces with long straight hairs which meet beyond the margin and completely hide the leaves. Flowers unknown."
South Island: Canterbury—Mount Cook, alt. 6500ft., Rev. W. S. Green.
This is quite unknown to me, and in the absence of additional information I have reproduced Mr. Kirk's description. It was discovered during the Rev. W. S. Green's adventurous ascent of Mount Cook, and has not since been met with.
9. GNAPHALIUM, Linn.
Hoary or woolly annual or perennial herbs. Leaves alternate, quite entire. Heads rather small, corymbose or fascicled or solitary, heterogamous and discoid. Involucre ovoid or canipanulate; braces imbricate in several series, more or less scarious, the inner sometimes with white spreading tips. Receptacle naked or pitted. Florets of the circumference all female, in 2 or more rows, numerous, filiform, minutely 3–4-toothed. Disc-florets hermaphrodite, fewer in number, tubular with a funnel-shaped 5-toothed mouth.

Pappus-hairs in one series, slender or thickened at the tip, caducous, often connate at the base.
A large genus, spread over the whole world, hardly distinguishable from Helichrysum and others except by the more numerous female flowers. Of the New Zealand species two are widely distributed in many countries, two others extend to Australia, the remainder are endemic.

Pappus-hairs few, very slender.—Handb. N.Z. Fl. 152; Kirk, Students' Fl. 297. G. adhærens, Col. in Trans. N.Z. Inst. xvii. (1885) 244.
North Island: Ruahine Range, Colenso! Andrew, Hewlett! Murimotu and Moawhango, Petrie! Rimutaka Range, Kirk! South Island: Not uncommon along the western side from Collingwood to the Otira Gorge and southwards to Milford Sound. Sea-level to 2500 ft. November–January.
A handsome plant, in its usual state at once recognised by the large size, broad distinctly 3-nerved leaves, and large heads. But small states with narrower leaves and smaller heads are difficult to separate from G. Keriense, and there is little doubt that the two species pass into one another. In both G. Lyallii and Keriense the disc florets are frequently sterile, showing a tendency in the heads to become unisexual.
2. G. trinerve, Forst. Prodr. n. 289.—Stems 1–2 ft. long, rather slender, sparingly branched, prostrate or decumbent, glabrate below, more or less white and cottony above.

Involucral bracts numerous, white, radiating, the outer woolly at the base. Achene linearoblong, glabrous. Pappus-hairs few, slender.—A. Rich. Fl. Nouv. Zel. 239; A. Cunn. Precur. n. 455; Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 138; Handb. N.Z. Fl. i. 153; Kirk, Students Fl. 297.
North Island: Rimutaka Range, Kirk! South Island: West coast of Nelson to Westland and INIilford Sound, south and east coasts of Otago; not uncommon. Sea-level to 2000 ft. November–December.
Closely allied to the preceding, but sufficiently characterized by the more slender stems, shorter obovate-spathulate leaves, which are seldom 3-nerved beneath, and by the bracteate peduncles.
3. G. Keriense, A. Cunn. Precur. n. 454.—Stems short or long, prostrate or decumbent, with numerous erect or ascending leafy branches 3–9 in. long, cottony above. Leaves spreading, ½–2½ in. long, 18–12 in. broad, narrow linear-lanceolate to oblonglanceolate or spatbulate-lanceolate, acute, gradually narrowed to the base, glabrous above, beneath white with appressed cottony tomentum but with the midrib evident, rarely faintly 3-nerved. Heads small, ⅓ in. diam., in many-flowered corymbs terminating the branches, which are produced into leafy or bracteate cottony peduncles. Involucral bracts numerous, white, radiating; outer cottony at the base. Achene minute, glabrous. Pappus-hairs few, very slender.—Raoul, Choix, 45; Hook. f. Fl. Nov. Zel. i. 138; Handb. N.Z. Fl. 153; Kirk, Students Fl. 298. G. novæ-zealandiæ, Sch. Bip. in Bot. Zeit. iii. (1845) 171. Helichrysum micranthum, A. Cunn. ex D.C. Prodr. vi. 189.

(1885) 245.—Stems usually much branched, sometimes almost bushy, erect or decumbent at the base, woody, 9–20 in. long; branches slender, brittle, somewhat rigid, glabrous or cottony at the tips. Leaves close-set, spreading, ½–1¼ in. long, 140–115 in. broad, very narrow-linear or narrow linear-spathulate, acute or apiculate, stiff and coriaceous, glabrous above, white with appressed tomentum beneath, but with the midrib evident; margins recurved. Heads very numerous, ⅓–½ in. diam., in broad many-flowered corymbs at the ends of the branches; pedicels usually very slender, almost capillary, white and cottony. Involucral bracts white and radiating. Achene and pappus as in G. Keriense.—G. Keriense var. linifolia, Hook. f. Fl. Nov. Zel. i. 138; Handb. N.Z. Fl. 153; Kirk, Students' Fl. 298.
North Island: Dry rocky banks from the East Cape and Taupo to Wanganui; not uncommon. Sea-level to 2000 ft. October–December.
This has generally been treated as a variety of G. Keriense, from which it differs in the more rigid erect and bushy habit, much narrower stiff and coriaceous leaves with recurved margins, and almost capillary pedicels. It deviates quite as much from G. Keriense as Lyallii and trinerve do, and for the sake of consistency should be considered as distinct, unless the four species are merged into one.
5. G. Traversii, Hook. f. Handb. N.Z. Fl. 154.—A dwarf tufted perennial herb 1–4 in. high, simple or branched below, sometimes forming small patches. Leaves radical, petiolate, ⅓–2 in. long, linear-spathulate or linear-obovate, clothed on both surfaces with soft cottony wool, petiole long or short. Scapes erect, variable in length, ½–3 in., white with cottony wool; bracts 1–3, linear. Head solitary, terminal, ⅓ in. diam.; involucral bracts in about 3 series, erect, linear, obtuse, pale brownish-yellow, scarious and hyaline, shining; outer shorter and broader, cottony at the base. Female florets very numerous, with a few hermaphrodite ones in the centre. Achene puberulous or glabrous. Pappus-hairs copious, very fine, connate at the base.—Benth. Fl. Austral. iii. 655; Kirk, Students' Fl. 299.
Var. Mackayi, T. Kirk, l.c.—Much branched, densely tufted, forming close matted patches. Leaves imbricated on the short branches, heads smaller, sessile or on short scapes. Involucral bracts not so numerous, acute.—Raoulia Mackayi, Buch. in Trans. N.Z. Inst. xiv. (1882) 354, t. 34, f. 2.
South Island: Not uncommon in mountain districts from Nelson to Foveaux Strait. 1500–5500 ft. December–February. Also in Australia.
A variable plant. The most developed form is almost simple, with long radical leaves and long and slender scapes; but it passes by almost imperceptible gradations into the extreme state of var. Mackayi, which forms broad much-branched patches, with short imbricated leaves and sessile heads.
6. G. paludosum, Petrie in Trans. N.Z. Inst. xxii. (1890) 441.—Very slender, solitary or tufted, 1–2 in. high. Leaves all radical, petiolate, ⅓–1½ in. long, narrow linear-spathulate; blade half the length or nearly so, acute or subacute, rather membranous, glabrous or slightly silky above, beneath clothed with white appressed tomentum; midrib prominent; margins flat or slightly recurved. Scapes few, hardly exceeding the leaves in the flowering stage, but elongating in fruit, very slender, almost capillary, cottony; bracts few, small, linear. Head solitary, terminal, 15 in. diam.; involucral bracts few, scarious, pale and glistening, darker at the tips, inner linear, glabrous. Female florets very numerous. Achene linear-oblong, papillose. Pappus-hairs very delicate, connate at the base.—Kirk, Students' Fl. 299. G. minutulum, Col. in Trans. N.Z. Inst. xxii. (1890) 472.
North Island: Base of Tongariro, Hill! Rangipo Plains and Ruahine Mountains, Petrie! South Island: Not uncommon in mountain districts, usually in peaty swamps, from Nelson to Otago. 1000–4000 ft. December–January.
Closely allied to G. Traversii, but easily separated by the smaller size and more slender habit, thinner leaves glabrous on the upper surface, smaller heads, and fewer involucral bracts with dark tips. The type specimens of Mr. Colenso's G. minutulum are identical with Mr. Petrie's plant.
7. G. nitidulum, Hook. f. Handb. N.Z. Fl. 154.—"A small densely tufted species, covered with appressed silky shining yellowish tomentum. Leaves closely imbricated at their bases, above spreading, flat, ⅓ in. long, linear, obtuse; lower ⅓ membranous, glabrous, upper ⅔ densely silky.

10. G. collinum, Lab. Pl. Nov. Holl. ii. 44, t. 189.—A tufted perennial herb 3–12 in. high, usually with creeping and rooting stolons and slender erect cottony stems. Leaves mostly radical, very variable in size, ⅓–3 in. long, lanceolate-spathulate or oblong-spathulate, acute or obtuse, petiolate, white and cottony on both surfaces or glabrate above; cauline leaves much smaller and narrower, linear-spathulate, sessile. Heads small, compacted into dense clusters or compound heads similar to those of G. japonicum, but smaller and not so compact, and with fewer smaller subtending floral leaves. Involucres broader than in G. japonicum; bracts linear-oblong, obtuse, scarious and hyaline. Florets and achenes as in G. japonicum.—Hook. f. Fl. Nov. Zel. i. 139; Handb. N.Z. Fl. 155; Benth. Fl.

Kermadec Islands, North and South Islands, Stewart Island, Chatham Islands: Plentiful from sea-level to 4500ft. November–March. The two varieties not uncommon on the mountains of the South Island.
Luxuriant forms of this are best distinguished from G. japonicum by being perennial, by the creeping stolons, smaller glomerules with fewer floral leaves, and by the broader involucres. It is also a native of Australia and Tasmania.
10. RAOULIA, Hook. f.
Perennial herbs, usually of small size, either densely tufted and compacted or creeping and matted. Leaves small, alternate, entire, often closely imbricated. Heads small, solitary, terminal, sessile or nearly so, heterogamous and discoid. Involucre oblong, campanulate or hemispherical; bracts imbricated in 2–3 series, the inner ones often with white radiating tips. Receptacle narrow, flat or convex, naked. Florets of the circumference in 1 or 2 rows, female, filiform, 2–3-toothed. Disc-florets hermaphrodite, tubular with a funnel-shaped 5-toothed mouth. Anthers sagittate at the base, produced into fine tails. Style-branches nearly terete, truncate or subcapitate. Achenes oblong. Pappus-hairs in one or several series, slender or thickened at the tip.
A genus founded more upon habit than upon really good and distinctive characters. It may be said to be intermediate between the Eugnaphalieæ and Helichryseæ, the female and disc florets being often nearly equal in number. It is easily divided into two sections by the remarkable differences between the pappus-hairs, which may ultimately, when the Gnaphalioid Compositæ are thoroughly worked out, be found sufficient to constitute separate genera. Several of the species are difficult of discrimination, and require further examination, this being specially the case with those to which, on account of the remarkable habit, the popular name of vegetable sheep has been applied. It is quite possible that several species are confounded under R. eximia and allied forms. All the New Zealand species are endemic, and in addition there are one or two found in Australia and Tasmania.

Var. lutescens, Kirk, l.c.—Smaller. Leaves densely imbricating, shorter, 120–112 in. long. Heads smaller; involucral bracts bright-yellow.
North Island: From the East Cape and the Upper Thames Valley southwards, but often local. South Island: Abundant throughout. Stewart Island: Mason Bay, Kirk! Sea-level to 5500 ft. December–January.
A very variable plant, especially in the size and shape of the leaves, and the extent to which they are clothed with white tomentum. Mr. Colenso describes his R. albosericea as having few florets and few pappus-hairs; but the specimens in his herbarium are long past flowering, and have evidently lost most of the florets and much of the pappus, and apparently do not differ from the type in any essential character.
2. R. tenuicaulis, Hook. f. Fl. Nov. Zel. i. 135, t. 36a.—Stems slender, prostrate and creeping, much and laxly branched, 1–10 in. long; branches ascending at the tips. Leaves laxly imbricating, spreading or recurved, 115–110 long linear-oblong or lanceolate-spathulate, or on luxuriant shoots obovate-spathulate, acuminate or apiculate, concave, more or less clothed with greyish appressed tomentum or almost glabrous. Heads 18–16 in. long; involucral bracts in 3 series; outer tomentose or glabrate, acute; inner scarious, with brown acute or obtuse tips.

North and South Islands: Not uncommon from the Thames goldfields southwards, usually on gravelly or sandy river-beds. Var. pusilla: Rimutaka Range, Kirk! mountains flanking the Wairau Valley, T.F.C. Sea-level to 5000 ft. December–January.
Easily distinguished by the slender habit, narrow acute or apiculate leaves with greyish tomentum, and brown-tipped involucral bracts.
3. R. Haastii, Hook. f. Handb. N.Z. Fl. 148.—Glabrous or nearly so, forming small dense patches. Stems short, rather stout, prostrate; branches numerous, closely packed, ½–1 in. high, rarely more. Leaves densely imbricated, erecto-patent, 116 in. long, with a broad membranous sheathing base and much narrower ovatesubulate coriaceous tip, concave, quite glabrous or obscurely silky or woolly. Heads 16 in. long; involucral bracts in 2–3 series, scarious, linear, obtuse, not brown at the tips. Florets few, 4 to 8; 2–4 of them female. Achene puberulous. Pappus-hairs copious, slender, not thickened above.—Kirk, Students' Fl. 302.

Separated from R. tenuicaulis by the shorter leaves with broad bases and ovate-subulate tips, and by the narrower few-flowered heads.
4. R. Monroi, Hook. f. Handb. N.Z. Fl. 148.—Stems wiry, creeping, much interlaced, forming broad patches; rootlets long, filiform; branches slender, ascending, silky, 1–2 in. high or more. Leaves laxly or densely imbricate, rarely distant, spreading and recurved, 18–14 in. long, linear or linear-spathulate, obtuse, uniformly clothed on both surfaces with greyish-white appressed tomentum; margins incurved. Heads narrow, 16 in. long; involucral bracts in 3–4 series; the outer oblong, tomentose; the inner longer and narrower, scarious, with brown obtuse tips. Florets from 15 to 20, the females the most numerous. Achene oblong, puberulous. Pappus-hairs copious, slender, not thickened at the tips.—Kirk, Students' Fl. 303.
South Island: Not uncommon in dry gravelly and sandy places in Marlborough, Canterbury, and Otago. Sea-level to 3500 ft. November–January.
Easily recognised by the uniform greyish-white colour, linear spreading and recurved leaves, and narrow heads with brown-tipped iuvolucral scales.
5. R. glabra, Hook. f. Fl. Nov. Zel. i. 135.—Stems long, slender, prostrate, much branched, forming lax patches 3–24 in. across; branches ascending, 1–3 in. long. Leaves pale yellow-green, laxly imbricated or somewhat remote, spreading or erecto-patent, 18–15 in. long, linear-ligulateor linear-oblong, acute or obtuse, flat or nearly so, 1-nerved, glabrous or slightly silky, sometimes with a minute pencil of hairs at the tip.

6. R. subsericea, Hook. f. Fl. Nov. Zel. i. 136.—Stouter than R. glabra, and more closely branched, forming smaller and more compact patches with shorter erect branches. Leaves rather longer and broader than in R. glabra, closely imbricated, 16–14 in. long, linear-oblong, obtuse or subacute, flat or nearly so, usually sparingly clothe(i with thin silvery tomentum or rarely almost glabrous. Heads rather larger, ⅓ in. diam.; involucral bracts broader, the innermost with larger and more conspicuous white radiating tips. Florets similar to those of R. glabra, but fewer in number.

Very closely allied to R. glabra, but generally recognised without difificulty by the more compact habit, silky leaves, rather larger heads with more conspicuous white tips to the inner involucral bracts, and by the pappus-hairs being slightly thickened above.
7. R. Parkii, Buch. in Trans. N.Z. Inst. xiv. (1882) 355, t. 34, f. 3.—Stems 1–6 in. long, prostrate, creeping and rooting, often densely matted and forming large patches; branches short, erect or ascendmg, ½–1 in. long.

Heads 16–14 in. diam., sessile among the terminal leaves; involucral bracts in 2–3 series; the outer short, tomentose on the outside; the inner longer, linearoblong, obtuse, with white radiating tips. Florets 15–25, the females about equal to the hermaphrodite ones in number. Achene puberulous. Pappus-hairs slightly thickened at the tips.
South Island: Canterbury—Mount Dobson, Lake Tekapo, Mount Ollivier, T. F. C. Otago—Mount Alta, Buchanan! Lake Wanaka, Hector Mountains, Old Man Range, Ida Valley, and elsewhere in Central Otago, Petrie! 2500–5500 ft. December–January.
Mr. Petrie's specimens and my own agree with Mr. Buchanan's figure, and exactly match a specimen which he gave me from Mount Alta, the original locality. In Mr. Kirk's herbarium it is placed under Helichrysum Youngii; but that species differs widely in the larger leaves clothed with softer tomentum, much larger heads with very much longer acute inner involucral bracts, and in the more numerous florets.
8. R. subulata, Hook. f. Handb. N.Z. Fl. 149.—A small densely tufted species forming moss-like patches 1–3 in. diam., perfectly glabrous in all its parts; branches ⅓–1 in. high. Leaves very closely imbricated, suberect or patent, 18–14 in. long, subulate, acuminate, 1-nerved. Heads 16 in. diam.; involucral bracts in 2–3 series, linear-oblong, scarious, acute, not white nor radiating. Receptacle convex, hispid. Florets 18–25, the females usually rather fewer in number than the hermaphrodite ones. Achene silky. Pappus-hairs somewhat rigid, thickened at the tips.—Kirk, Students' Fl. 304.
South Island: Nelson—Mountains above the Wairau Gorge, Sinclair, T.F.C. Canterbury—Mountains above Arthur's Pass, T.F.C.; Rangitata Valley, Armstrong! Otago—Lake district, Hector and Buchanan! Hector Mountains, Mount Pisa, Mount Tyndall, Petrie! 4000–6500 ft. December–January.
A well-marked species, not closely related to any other.
9. R. eximia, Hook. f. Handb. N.Z. Fl. 149.—Forming large rounded or amorphous densely compacted masses from 2–3 in. to several feet long, and sometimes over 2 ft. high. Root stout, woody; branches short, with the leaves ¼ in. diam. Leaves most densely packed, imbricated all round the branch in many series, 18–15 in. long, linear-obovate or linear-cuneate, rounded at the tip, membranous, bearing on both surfaces towards the tip a dense tuft of straight white hairs which project beyond the leaf and entirely conceal it. On the back of the leaf the hairs often extend half-way down the leaf or more, but on the upper surface the lower two-thirds is usually quite glabrous. Heads numerous, small, sunk among the leaves at the tips of the branches; involucral bracts in 2 series, narrow-linear, scarious, wiih a tuft of hairs above the middle, not white at the tips. Florets 8–12 or more, the hermaphrodite ones more numerous than the female. Achene clothed with long silky hairs, and with a thickened areole at the base. Pappus-hairs few, rigid, thickened at the tip.—Kirk, Students' Fl. 304.
South Island: Nelson—Mount Peel, T.F.C. Canterbury—Mount Torlesse, Haast, Kirk! Enys! Petrie! Cockayne! T.F.C.; Mount Dobson, Haast, T.F.C; Mount Cook district, T.F.C. Otago—Lake district, Buchanan! Mount Ida Range, Petrie! 4000–6000 ft. December–January.
A most remarkable plant. It is probably not uncommon in alpine situations all along the eastern side of the Southern Alps from Nelson to Otago, but I have only quoted those localities from whence I have seen flowering specimens. In a barren state it is very easy to confound it with R. mammillaris.}}
There are several forms closely related to R. eximia respecting which further information is much wanted. Mr. Townson sends a variety from Mount Frederic, near Westport, remarkable for the branches being quite flat at the tips, and so closely compacted that the tips show on the even surface of the hummock like mosaic. On the other hand, specimens collected by myself in the Mount Cook district are much less dense, the tips of the branches forming conspicuous mammillary knobs. I have seen no specimens of Mr. Kirk's var. lata, apparently distinguished by the broader and shorter less closely imbricate leaves. Nor are there any specimens in his herbarium of R. Brownii, Kirk, provisionally separated from R. eximia on account of the linear-oblong acute leaves.
10. R. Hectori, Hook. f. Handb. N.Z. Fl. 149.—Often forming broad dense patches. Stems prostrate, much branched, 1–3 in. long; branches ½–2 in. high, close-set, erect or ascending. Leaves closely imbricated, erecto- patent, 110–18 in. long, broadly ovate, obtuse, upper half thick and coriaceous and clothed with appressed silvery tomentum, lower half membranous, glabrous, back longitudinally grooved when dry. Heads small, 110–16 in. diam., sunk amongst the terminal leaves; involucral bracts in 2 series, linearoblong, scarious, subacute, glabrous, not white at the tips. Florets 10–18; female 3–6. Achene glabrous or nearly so. Pappus-hairs few, rigid, thickened at the tips.—Kirk, Students' Fl. 304.
Var. mollis, Buch. ex Kirk, Students' Fl. 305.—Smaller and not so rigid. Leaves not so closely imbricated, broader and softer, cottony at the base, not so silvery at the tip. Heads smaller. Florets 6–10. Achenes glabrous. Perhaps a distinct species.
South Island: Canterbury—Mount Dobson Range, T.F.C. Otago—Lake district, Hector and Buchanan! Mount St. Bathans, Hector Mountains, Mount Pisa, Ben Lomond, Petrie! 4000–6500 ft. December–January. Var. mollis: Mount St. Bathans, Petrie!
11. R. grandiflora, Hook. f. Fl. Nov. Zel. i. 136, t. 37a.—Stems ½–2 in. long, tufted, simple or branched at the base, stout, ⅓–½ in. diam. with the leaves, erect or curved; roots long and wiry. Leaves imbricated all round the stem, 16–13 in. long, ovate- or lanceolate-subulate, gradually tapering to a subacute tip, rigid, striate on the back, clothed with silvery appressed tomentum, loosely cottony towards the base. Heads large, ⅓–⅔ in. diam., sunk among the terminal leaves; involucral bracts in about 2 series; the outer few, short, scarious; inner linear, obtuse, spreading, with long white radiating tips; receptacle small, convex, hispid. Florets 25–40, about one-third female, narrow, the rest hermaphrodite. Achene silky. Pappus-hairs rather slender, thickened at the tips.—Handb. N.Z. Fl. 150; Kirk, Students' Fl. 305.
North and South Islands: Frequent in mountain districts from the East Cape and Taupo to Foveaux Strait. 3000–6000 ft. December–January.
This has a different habit to any of the other species included in the genus, and would be far more appropriately placed in Helichrysum.
12. R. Petriensis, T. Kirk in Trans. N.Z. Inst. ix. (1877) 519.—Usually forming laxly branched patches. Stems 2–6 in. long, prostrate or suberect; branches numerous, ascending or erect, viscid, with the leaves 16–15 in. diam. Leaves laxly imbricating, 15–14 in. long, obovate-spathulate; base erect, membranous, loosely cottony; tip spreadmg or recurved, rounded, coriaceous, clothed with densely felted shining tomentum. Heads ¼ in. diam., sessile among the terminal leaves; involucral bracts in 2 series, linear, scarious, obtuse, the inner with short white radiating tips. Florets 30–50; female very slender, filiform, 8–15. Achene glabrous or puberulous. Pappus-hairs thickened at the tips.—Students' Fl. 305.
South Island: Canterbury—Mount Dobson Range, T.F.C. Otago—Mount Ida and Mount St. Bathans, Petrie! 3500–5500 ft. December–January.
A remarkably distinct species, at once recognised by the loosely tufted habit, long slender branches, spreading and recurved leaves, and numerous florets.
13. R. mammillaris, Hook. f. Handb. N.Z. Fl. 150.—Forming hard compact masses similar in size and aspect to those of R. eximia. Branches short, stout, with the leaves quite ¼ in. diam. Leaves most densely packed, imbricated all round the branches in many series, spreading, 112–18 in. long, obovate-cuneate or spathulate, rounded or almost truncate at the tip, membranous, glabrous or nearly so in the lower half, in the upper half clothed on both surfaces with a dense tuft of straight hairs which project just beyond the tip and conceal the leaf. Heads 16–14 in. diam., sunk among the leaves at the tips of the branches; involucral bracts in about 2 series, the inner linear-oblong, scarious, with conspicuous white obtuse or subacute radiating tips. Florets 10–12, the hermaphrodite ones more numerous than the females. Achene clothed with long silky hairs, and with a thickened areole at the base. Pappus-hairs few, rigid, thickened at the tips.—Kirk, Students' Fl. 306.
South Island: Nelson—Mount Starveall, Bryant ("Students' Flora"). Canterbury—Mount Torlesse, Haast (Handbook). Otago—Alps of the Lake district, Buchanan! 4000–6000 ft. Vegetable sheep.
The conspicuous white radiating tips to the inner involucral bracts distinguish this at a glance from R. eximia, but in the absence of flowers it is by no means easy to separate the two species. The leaves of R. mammillaris, however, are shorter and broader, with shorter hairs which do not project so far beyond the tip of the leaf as in R. eximia. The only specimens I have seen are Mr. Buchanan's, which are in full flower, and unmistakable. The Mount Starveall locality is given on the authority of Mr. Kirk, but there are no specimens from thence in his herbarium.
14. R. rubra, Buch. in Trans. N.Z. Inst. xiv. (1882) 350, t. 30, f. 2.—Forming hard compact masses 6–12 in. diam. and 4–8 in. high; branches with the leaves 16–15 in. diam. Leaves closely packed, imbricated in many series, 18–16 in. long, broadly obovate-spathulate or cuneate, rounded or almost truncate at the tip, membranous, upper part clothed on both surfaces with long straight hairs which project beyond the leaf, but the extreme tip naked on both sides though concealed by the hairs, lower portion of the leaf glabrous on both surfaces. Heads small, 110 in. diam., sunk among the terminal leaves; involucral bracts numerous, linear, obtuse, glabrous, the inner with short white radiating tips. Florets 10–14; corolla dark-crimson. Achene clothed with long silky hairs. Pappus-hairs few, rigid, thickened at the tips.—Kirk, Students' Fl. 305.
North Island: Mount Holdsworth, Tararua Range, alt. 4500 ft., Buchanan! T. P. Arnold! January.
I have only seen very imperfect specimens of this, and the above description is mainly founded on that originally published by Buchanan. Its nearest ally appears to be R. manimillaris.
15. R. Buchanani, T. Kirk, Students' Fl. 307.—Apparently forming hard compact masses. Branches short, stout, with the leaves on ¼ in. diam. Leaves closely packed, imbricated in several series, 18–16 in. long and almost as broad at the tip, broadly cuneate, truncate, membranous; upper surface with the lower twothirds quite glabrous, above that clothed with straight hairs which project just beyond the tip, forming a kind of fringe; undersurface with the lower half loosely cottony, the upper half glabrous, more or less corrugated or wrinkled. Heads unknown.
South Island: Otago—Mount Alta, Buchanan!
A very remarkable plant, the exact position of v?hich must remain doubtful until the flowers have been observed. It is probably nearest to P. Goyeni. The leaves difier from those of any other species in the broad truncate tips densely hairy above, but glabrous and wrinkled beneath.
16. R. Goyeni, T. Kirk in Trans. N.Z. Inst. xvi. (1884) 373.—Forming hard compact greenish masses from a few inches to 2 or 3 ft. long, but rarely more than 6 or 8 in. high. Branches very short, closely compacted and often subangular from mutual pressure, with the leaves 15–14 in. diam. Leaves very closely packed, densely imbricated in many series, 18–16 in. long, linear-oblong, sessile by a broad base, rather wider and truncate at the tip, glabrous beneath, on the upper surface bearing near the tip a dense tuft of straight white hairs slightly longer than the leaf, the extreme upper margin naked although concealed by the hairs. Heads small, deeply sunk among the leaves at the tips of the branches; involucral bracts in 2 series; the outer linear-spathulate, scarious, bearing a tuft of hairs at the tip; the inner linear, scarious, obtuse, some of them with short hardly radiating white tips. Florets few. Achene hispid, with a thickened areole. Pappus-hairs few, thickened upwards.—Students' Fl. 306.
Stewart Island: Rakiahua, P. Goyen! Kirk! Smith's Lookout and Mount Anglem, Kirk! 1000–3300 ft.
17. R. bryoides, Hook. f. Fl. Nov. Zel. ii. 332.—Forming hard and dense convex patches 2–8 in. diam. Lower portion of the stem hard and woody, roots long and stringy. Branches short, stout, with the leaves 18–14 in. diam. Leaves very closely packed, imbricated in several series all round the branch, erecto-patent, 110–16 in. long, narrow obovate-spathulate or rhomhoid-spathulate, subacute or obtuse; lower two-thirds glabrous or slightly woolly, upper one-third about triangular, coriaceous, clothed on both surfaces with closely felted silky hairs which do not conceal the shape of the leaf, and with a tuft of cottony wool on each side. Heads 15–14 in. diam., sunk among the terminal leaves; involucral bracts in 2–3 series, linear-oblong, scarious, acute, inner with white radiating tips. Florets 8–14, the hermaphrodite ones more numerous than the females. Achene with long silky hairs and a thickened areole at the base. Pappus-hairs few, rigid, thickened at the tips.—Handb. N.Z. Fl. 150; Kirk, Students' Fl. 307.
South Island: Common on the mountains of Nelson and Marlborough. Canterbury—Mount Torlesse, Cockayne! Black Range, T.F.C.; Craigieburn Mountains, Petrie! Otago—Mount Pisa and the Hector Mountains, Petrie! 3500–6500 ft. December–January.
Easily distinguished from R. eximia, R. mammillaris, &c., by the hairs on the leaves not enveloping them so as to conceal their shape.
11. HELICHRYSUM, Vaill.
Herbs or small shrubs, very variable in habit, often woolly or tomentose. Leaves alternate or the lower rarely opposite, quite entire. Heads solitary or corymbose, heterogamous and discoid or homogamous through the suppression of the female florets. Involucre from cylindrical to broadly hemispherical; bracts in several series, with or without white or coloured spreading petal-like scarious tips. Receptacle flat or convex, naked or pitted. Female florets exterior, few, sometimes altogether wanting, filiform, minutely 2–3-tooched. Disc-florets hermaphrodite, numerous, tubular with a funnel-shaped 5-toothed mouth. Anthers sagittate at the base, produced into fine tails. Style-branches of the disc-florets almost terete, truncate or subcapitate. Achenes small, terete, 5-angled or compressed. Pappus-hairs in one series (rarely in several series), free or connate below, simple or barbellate or plumose above.
A very large and heteromorphous genus, found in most parts of the world, and especially plentiful in South Africa and Australia. It has been united with Gnaphalium by many authors, but can usually be distinguished by the hermaphrodite florets being always much more numerous than the female ones. All the New Zealand species are endemic.

1. H. bellidioides, Willd. Sp. Plant. iii. 1911.—Stems slender, prostrate, much branched, ahiiost woody at the base, 6–18 in. long; branches numerous, erect or ascending, leafy. Leaves loosely imbricate or almost distant, spreading or recurved, ¼–½ in. long, obovate-spathulate or obovate-oblong, obtuse or apiculate, flat. 1-nerved, upper surface slightly cottony or glabrous, beneath clothed with cottony appressed tomentum. Heads solitary, ½ in. diam. or more, on bracteate cottony peduncles 1–5 in. long terminating the branches; involucral bracts in many series, linear-ligulate, ¼–⅓ in. long, with scarious tomentose claws and long white radiating tips. Eeceptacle convex or almost conical. Florets very numerous; females few, in 1 or 2 series. Achene glabrous, with a thickened areole at the base. Pappus-hairs few, slender.—A. Cunn.

Nouv. Zel. 242.
Var. prostratum, Kirk, Students' Fl. 309.—Similar to the type, but heads sessile at the tips of the branches.—H. prostratum, Hook. f. Fl. Antarct. i. 30, t. 21. Gnaphalium prostratum, Hook f. Fl. Nov. Zel. i. 137; Handb. N.Z. Fl. 152.
North and South Islands, Chatham Islands, Stewart Island, Auckland and Campbell Islands, Antipodes Island: Abundant in mountain districts from the East Cape and Taupo southwards. Sea-level to 5000 ft. November–February. Var. prostratum: Sparingly found in both North and South Islands, more abundant in the Auckland and Campbell Islands.
A common plant. I quite agree with Mr. Kirk in considering H. prostratum to be a variety only, and there is no difficulty in collecting passage-forms from no peduncles to very long bracteate ones. But I do not find the conical receptacle to be peculiar to var. prostratum.
2. H. Purdiei, Petrie in Trans. N.Z. Inst. xxii. (1890) 440.—Stems slender, wiry, prostrate, spreading, much branched, woody at the base, 1–2 ft. long; branches white and tomentose at the tips. Leaves distant, spreading, ¼–½ in. long, obovate-spathulate, rounded at the tip and minutely apiculate, flat, rather membranous, pubescent or almost glabrous above, beneath clothed with laxly appressed greyish-white tomentum. Heads ¼ in. diam., in corymbs of 3 to 6 terminating the branchlets; peduncles and pedicels short, slender, tomentose. Involucral bracts in several series; the outer very short, obtuse, brown and scarious; the inner linear-oblong with short white radiating tips. Florets very numerous; females few, in 1–2 series. Achene glabrous, with a thickened areole at the base. Pappus-hairs few, slender, barbellate above.—Kirk, Students' Fl. 309.
South Island: Otago—Dunedin Harbour, rare, A. C. Purdie! Petrie! Aston! November–December.
3. H. filicaule, Hook. f. Fl. Nov. Zel. i. 140, t. 36b.—Rhizome long, wiry, creeping, putting up numerous very slender siniple or rarely branched erect cottony stems 3–10 in. high. Leaves distant, ¼–⅓ in. long, obovate-oblong or narrow-oblong, obtuse or apiculate, glabrous or slightly cottony above, beneath clothed with white cottony tomentum. Heads solitary, terminal on long filiform peduncles, ⅓ in. diam.; involucral bracts in about 4 series; the outer shorter, oblong, obtuse, cottony at the base; inner longer, linear-oblong or linear, acute, scarious. Eeceptacle small, convex. Florets numerous; females few, in 1 series. Achene obscurely papillose or puberulous. Pappus-hairs very slender.—Kirk, Students' Flora, 309. Gnaphalium filicaule, Hook. f. Handb. N.Z. Fl. 153.
North and South Islands, Chatham Islands, Stewart Island: Not uncommon in dry grassy places from Rotorua southwards. Sea-level to 4000 ft. December–February.
4. H. Sinclairii, Hook. f. Handb. N.Z. Fl. 153.—"A small subalpine species; stems and branches ascending, leafy, 2–4 in. high. Leaves close-set, spreading, ¼–⅓ in. long, ⅙ in. broad, linear-oblong or obovate-spathulate, obtuse, densely covered with pale cottony tomentum on both surfaces. Heads ¼ in. diam., in numerous rounded terminal dense corymbs ½–1 in. across; peduncles and pedicels short, densely cottony; outer scales of involucre cottony, inner shortly radiating; female florets in 1 series; pappus of few stout hairs, thickened towards the tip. Achene glabrous."—Kirk, Students' Fl. 309.
South Island: Marlborough—Upper Awatere Valley, Sinclair (Handbook).
This has not been observed since its first discovery, nearly fifty years ago. Not having seen specimens, I have reproduced Hooker's description. He compares it with the Tasmanian Raoulia catipes (Hook. f. Fl. Tasm. i. 206, t. 58), but states that the leaves are smaller, the heads not half the size, and much more numerous.
5. H. Youngii, Handb. N.Z. Fl. 152.—Densely tufted, forming broad soft patches ¾–1½ in. high; branches stout, erect, with the leaves ⅓ in. diam. Leaves densely imbricate, erecto-patent or spreading, ⅙–¼ in. long, obovate-oblong, obtuse, sessile by a broad base, densely clothed on both surfaces with soft white or buff cottony tomentum. Heads ⅓–½ in. diam., sessile amongst the terminal leaves; involucral bracts in about 3 series; the outer shorter, woolly and tomentose at the base; the inner longer, linear-oblong, acute, with white radiating tips almost equalling the scarious claw, and much exceeding the florets. Florets numerous, 50–70; about 20–30 females, in 2 series. Achene pubescent. Pappus-hairs few, rigid, brittle, slightly thickened above.—Kirk, Students Fl. 310.
South Island: Canterbury—Mount Torlesse and Mount Cook, Haast! T.F.C. Otago—Lake Hawea, Haast; Lake Wanaka, Buchanan! Mount Pisa, Mount Cardrona, Hector Mountains, Petrie! 4500–6500 ft. January.
This differs from Helichrysum in habit and in the numerous female florets, and would perhaps be more appropriately placed in Raoulia, of which it has the pappus-hairs of the section Imbricaria. In Mr. Kirk's herbarium it is mixed with Raoulia Parkii, the distinguishing characters of which have already been pointed out under the genus Raoulia.
6. H. fasciculatum, Buch. in Trans. N.Z. Inst. ix. (1877) 529, t. 19.—Densely tufted, much branched below, forming small patches 1–2 in. high; branches with the leaves ½ in. diam. or more. Leaves closely imbricated, erect or spreading at the tips, ¼–½ in. long, oblong-lanceolate or narrow obovate-lanceolate, acute, narrowed towards the base, clothed on both surfaces with white silvery tomentum, which becomes loose and cottony towards the base, grooved beneath. Heads in fascicles of 2–4 at the tips of the branches, sessile, ⅓–½in. diam.; involucral bracts in 3 series, scarious, linear-oblong, obtuse, tomentose on the back, the inner with white radiating tips. Eeceptacle narrow, hispid. Florets 12–20; female few, in 1 series. Achene silky, with a thickened areole at the base. Pappus-hairs few, slightly thickened above.—Kirk, Students' Fl. 310.
North Island: Tararua Mountains, H. B. Travers! South Island: Nelson—Mount Starveall, Bryant ("Students' Flora"). 4000–5000 ft. December–January.
I have seen very imperfect specimens of this, which is evidently a very distinct species. The silvery foliage is much like that of Raoulia grandiflora.
7. H. Loganii, T. Kirk, Students' Fl. 310.—"Forming pulvinate masses 6–12 in. diam. Branches slender, woody at the base, with the leaves ⅓–⅜ in. diam., the whole plant clothed with soft white or greenish-white wool. Leaves densely imbricating, ¼ in. long, obovate or obovate-oblong, rounded at the tip or subacute, membranous, 3-nerved, tips recurved, clothed with long soft hairs, which are restricted to a dense tuft above projecting beyond the margin. Heads ½–¾ in. diam.; involucral bracts in 3 series, oblong, mostly obtuse, the outer villous, the inner broader, glabrate, scarious, pale, not radiating. Achene compressed, covered with long silky hairs. Pappus-hairs barbellate, irregularly thickened towards the apex."—Haastia Loganii, Buch. in Trans. N.Z. Inst. xiv. (1882) 350, t. 30, f. 3.
South Island: Mount Holdsworth, Tararua Range, Buchanan! T. P. Arnold! 4000–5000 ft.
The above description is Mr. Kirk's. I much regret that I have had no opportunity of examining good specimens, particularly as an old and very imperfect fragment in Mr. Buchanan's herbarium seems to show that the heads are fascicled, and not solitary, as might be supposed from the original description and plate.
8. H. Leontopodium, Hook. f. Fl. Nov. Zel. i. 141, t. 37b.—Stems much branched, decumbent and woody at the base, erect or ascending at the tips, 2–8 in. high. Leaves densely imbricate, erect or rarely patent, ⅓–¾ in. long, linear-oblong or oblong-lanceolate, acute, clothed on both surfaces with appressed shining silvery tomentum, striate when dry. Peduncles stout, terminating the branches, more or less densely clothed with imbricating bracts. Heads 8–15 together, congested into a dense bracteaie glomerule ½–1 in. diam.; each head about ⅙ in. across; bracts 10–20, spreading, ¼–¾ in. long, oblong or ovate-oblong, obtuse or subacute, most densely woolly. Involucral bracts in 2 series, linear-lanceolate, woolly on the back, erect, scarious, shining. Florets numerous; females few, in 1 series. Achene silky. Pappus-hairs few, stout, scabrid, slightly thickened above.—Kirk, Students' Fl. 313. Gnaphalium Colensoi, Hook. f. Handb N.Z. Fl. 154.
North Island: Mount Hikurangi (East Cape), Colenso! Adams and Petrie! Ruahine Mountains, Colenso! Petrie! Hill! Tongariro, Hill! Tararua Range, H. H. Travers! Budden. South Island: Nelson—Raglan Range and mountains above the Wairau Gorge, T.F.C.; Tarndale, Sinclair; mountains above the Rainbow River, Bryant. 4000–6000 ft. January–February.
A beautiful little plant, with precisely the aspect of the edelweiss of the European Alps (Leontopodium alpinum), but with flower-heads of different structure.
9. H. grandiceps, Hook. f. Handb. N.Z. Fl. 154.—Densely tufted. Seems much branched, decumbent and woody at the base, 2–8 in. high; branches ascending or erect. Leaves densely imbricate, spreading or recurved, ¼–⅓ in. long, oblong- or obovate-spathulate, obtuse, flat or concave, clothed on both surfaces with appressed silvery tomentum. Peduncles composed of the elongated tips of the branches, leafy throughout, but the leaves usually not so closely imbricate. Heads congested into a terminal bracteate glomerule surrounded by leafy bracts, as in H. Leontopodium, but bracts rather shorter and broader. Involucral bracts in 2 series, linear, tomentose on the back, with brown scarious tips. Florets numerous; females few, in 1 series. Achene silky. Pappus-hairs few, rather stout, thickened above.—Kirk, Students' Fl. 313.
South Island: Not uncommon in mountain districts from Nelson to Otago. 2500–5000 ft. December–January.
Allied to H. Leontopodium, but amply distinct in the shorter and broader usually recurved leaves, more densely leafy peduncles, shorter and broader bracts, and smaller glomerules.
10. H. glomeratum, Benth. and Hook. f. Gen. Plant. ii. 311.—A much-branched shrub 3–8 ft. high; branches spreading, slender, flesuous, grooved, tomentose above. Leaves alternate, very variable in size, ¼–1½ in. long, orbicular or broadly ovate or ovate-spathulate, obtuse or minutely apiculate, suddenly narrowed into a short slender petiole, quite entire, flat; upper surface glabrous, minutely reticulate; beneath clothed with white cottony tomentum. Heads in terminal or lateral sessile or stalked subglobose corymbs, small, 110 in. diam. Involucral bracts few, in about 3 series, oblong, obtuse, scarious, woolly at the base. Florets 8–12, 2 or 3 of them female. Achene puberulous, with a thickened areole at the base. Pappus-hairs thickened at the tips.—Kirk, Students' Fl. 311. Ozothamnus glomeratus, Hook. f. Fl. Nov. Zel. i. 133; Handb. N.Z. Fl. 146. Swammerdammia glomerata, Raoul, Choix, 20, t. 16.
North and South Islands: Not uncommon from the North Cape southwards. Sea-level to 2500 ft. November–January.
11. H. lanceolatum, T. Kirk, Students' Fl. 311.—Altogether similar to H. glomeratum, but leaves 1–1½ in. long, lanceolate or elliptic-lanceolate, acute or subacute, narrowed into a short winged petiole, glabrous above, beneath clothed with white appressed tomentum; margins flat or slightly undulate. Heads, florets, and achenes precisely as in H. glomeratum.—Ozothamnus lanceolatus, Buch. in Trans. N.Z. Inst. ii. (1870) 88.
North Island: Mountains near Hokianga, Buchanan! alt. 2000 ft.
Probably only a narrow-leaved variety of the preceding. I have seen no specimens except Mr. Buchanan's.
12. H. depressum, Benth. and Hook. f. Gen. Plant. ii. 311.—A suberect or rarely prostrate much-branched bush 1-5 ft. high, hoary in all its parts with appressed greyish-white tomentum; branches spreading, rigid and wiry, often tortuous. Leaves minute, closely appressed to the branch, laxly imbricating, 112–110 in. long, linear, obtuse, concave and loosely woolly on the inner face, silky or woolly on the back. Heads small, ⅙ in. diam., solitary, sessile at the tips of the branchlets; involucral bracts few, linear, scarious, acute or acuminate, rarely obtuse, glabrate or cottony at the base. Florets 8–12; females few, 2–3. Achene glabrous or puberulous. Pappus-hairs in several series, copious, slender.—Kirk, Students' Fl. 311. Ozothamnus depressus, Hook. f. Fl. Nov. Zel. i. 134, t. 35b; Handb. N.Z. Fl. 146.

A most puzzling plant, exceedingly variable in the size of the leaves and the extent to which they are toothed or divided, and also varying much in the size of the flower-heads. Mr. Kirk divided it into three species; but these are clearly connected by intermediate forms, and cannot always be distinguished by the descriptions he has given. The following are the chief varieties, but it must be borne in mind that the characters used to separate them are purely arbitrary.
Var. a.—Leaves 1–2 in., obovate-spathulate, membranous, flaccid, toothed or lobulate above, pinnatifid below, segments entire or toothed. Abundant.
Var. crenatifolia, Kirk, Students' Fl.—Leaves ¾–3 in., oblong-spathulate, membranous, crenate-toothed, with a few deeper divisions at the base of the leaf. Mountain swamps in the South Island.

North and South Islands: Shores of Cook Strait, Buchanan! Kirk; Westport, Dr. Gaze! Greymouth, Helms! Rangiora. July–September.
I consider this to be a trivial variety of B. repanda, from which it differs in no important character. But as both Kirk and Buchanan treated it as a distinct species, and as they were supported by the late Dr. Mantell, who had it in cultivation for many years, I have retained it for the present. It appears to keep its characters, such as they are, under cultivation.
21. SENECIO, Linn.
Herbs, shrubs, or small trees of exceedingly various habit, glabrous or pubescent or more or less woolly or tomentose. Leaves alternate, entire or variously divided. Heads solitary or corymbose or paniculate, heterogamous and radiate or homogamous and discoid. Involucre from cylindrical to hemispherical; bracts in 1 or 2 series, nearly equal, erect, free or connate below, usually with a few much shorter ones at the base. Receptacle flat or convex, naked, pitted or fimbrillate. Florets of the circumference female, ligulate, sometimes sterile or wanting. Disc-florets hermaphrodite, tubular, 5-toothed. Anthers obtuse at the base or minutely tailed. Style-branches of the hermaphrodite florets recurved, their tips truncate or penicillate. Achenes subterete, usually ribbed or striate. Pappus-hairs copious, soft, white, smooth or scabrid or barbellate.
The largest genus of Compositæ, if not of flowering plants generally, probably containing fully 1,000 species. It is found in all parts of the world, stretching from the equator to the limits of phænogamic vegetation in both the arctic and antarctic regions, but is most abundant in temperate and mountainous districts. Few of the species have wide ranges, and many have a very restricted distribution. Of the 30 found in New Zealand, one extends to Australia, the rest are all endemic. The herbaceous species are exceedingly variable, and some of them difficult to determine; but the shrubby varieties are remarkably distinct. Some of them, such as S. Hectori and S. Kirkii, must be ranked amongst the most beautiful members of the flora.

South Island: Port Lyttelton and other localities on Banks Peninsula, not uncommon. January–March.
A handsome species, separated from large states of S. lagopus, some of which approach it very closely, by the much stouter habit, more copious villous hairs, and larger thicker leaves, which are silky above and never show the stout bristly hairs so characteristic of S. lagopus and bellidioides.
5. S. Lyallii, Hook. f. Fl. Nov. Zel. i. 146.—A leafy herb 1–2 ft. high or more, usually glandular-pubescent or almost villous, rarely glabrate. Rootstock thick, crowned with long silky hairs.

Kermadec Islands, North and South Islands, Stewart Island, Chatham Island: Abundant near the sea, not so common inland. Sea-level to 4500ft. October–March.
This is a widely diffused plant in Australia and Tasmania as well as New Zealand, and is everywhere exceedingly variable, not a few forms having been described as distinct species. The chief varieties found in New Zealand may be briefly characterized as follows, but it must be borne in mind that intermediates are not uncommon:—
Var. a.—Much branched, erect or decumbent. Leaves deeply pinnatifid; segments long and narrow, often again toothed, rarely short and broad. Heads ⅓–½ in. diam., radiate.—Usually near the coast, but occasionally found inland. Mr. Kirk's variety carnosulus is probably a form of this.
Var. montanus.—Sparingly branched or quite simple, erect. Leaves oblong to lanceolate or spathulate, entire or toothed or shortly pinnatifid. Heads ½–¾ in. diam., radiate; rays often revolute.—A common mountain plant in both the North and South Islands.
Var. discoideus.—Sparingly branched, prostrate or decumbent, rarely erect. Leaves very fleshy, obovate or spathulate, coarsely toothed or lobed, sometimes pinnatifid below. Heads large, ½–¾ in. diam.; rays wanting.—Mountain districts in the South Island.
Var. radiolatus, Kirk, Students' Fl. 341.—More or less pubescent. Lower leaves broad, membranous, narrowed into slender petioles, toothed or lobed or pinnatifid; upper sessile, auricled at the base. Heads ⅓–½ in., radiate; rays short, broad. Achenes very mucilaginous when soaked in warm water.—S. radiolatus, F. Muell. Veg. Chath. Is. 24, t. 4. Chatham Islands, H. H. Travers! Cox and Cockayne!
8. S. glaucophyllus, Cheesem. in Trans. N.Z. Inst. xxviii. (1896) 536.—Smooth and glaucous, perfectly glabrous, 1–3 ft. high. Rootstock stout, woody. Stems numerous, strongly grooved, simple or sparingly branched, naked at the base or with minute scale-like leaves only, leafy above. Leaves 2–4 in. long, ½–1 in. wide, oblanceolate or oblong-obovate or obovate-spathulate, obtuse or subacute, gradually narrowed into broad flat petioles, not dilated nor sheathing at the base, irregularly sinuate-dentate or serrate, rather thin, very glaucous; margins somewhat thickened. Upper leaves narrower, lanceolate or linear-lanceolate, serrate, gradually passing into narrow-linear entire bracts. Heads several in a loose terminal corymb, broadly campanulate, ⅓ in. diam.; involucral bracts linear, acuminate, 2-ribbed, glabrous or pilose at the tips. Eay-florets about 15; disc-florets numerous, Achenes not seen.—Kirk, Students' Fl. 343.
South Island: Nelson—Mount Arthur, on limestone rocks, alt. 4000 ft., T.F.C. January.
A very curious plant, its bushy mode of growth and glaucous leaves giving it a very different appearance to any of its allies. The stems appear to die down to the root in winter, a fresh crop appearing in the following spring. My specimens are in young flower only, and the above description may require modification when more perfect examples have been obtained.
9. S. latifolius, Banks and Sol. ex Hook. f. Fl. Nov. Zel. i. 145.—A tall erect much-branched glabrous herb 2–4 ft. high; stems flexuous, grooved.

Corymbs broad, lax, much branched; branches slender. Heads very numerous, ½–¾ in. diam.; involucral bracts in 1 series, linear, acuminate, glabrous or pubescent. Ray-florets 12–20; ligule narrow, spreading. Disc-florets 30–40. Achenes linear, grooved, hispidulous. Pappus-hairs soft, copious, white.—Hook. f. Handb. N.Z. Fl. 159; Kirk, Students' Fl. 341.
Var. rufiglandulosus, Kirk, l.c.—Glandular-pubescent or glabrate. Leaves coarsely and sharply irregularly doubly dentate or serrate, sometimes lobed at the base. Corymbs very large. Achenes densely pubescent.—S. rufiglandulosus, Col. in Trans. N.Z. Inst. xxviii. (1896) 599.
Var. sinuatifolius, Kirk, l.c.—Stems slender, flexuose. Leaves distant, ovate-oblong, sinuate, not toothed. Corymbs small; heads few.

Leaves 2–5 in. long, 1–2 in. broad, broadly oblong or ovate-oblong to linear-oblong, acute or subacute, sessile with broad auricled amplexicaul bases, coriaceous or almost membranous, shining, often glaucous, coarsely and irregularly sinuate-serrate or dentate; veins reticulated, often prominent beneath; uppermost leaves smaller and narrower, lanceolate or linear. Corymbs broad, lax. Heads numerous, campanulate, ¼–⅓ in. broad; involucral bracts linear-oblong, acuminate, pubescent at the tips. Ray-florets 10–12; ligules short, revolute. Achenes linear, grooved, pubescent.—Handb. N.Z. Fl. 734; Kirk, Students' Fl. 342. S. odoratus, Hook. f. Handb. N.Z. Fl. 160 (not of Hornemann). S. pumiceus, Col. in Trans. N.Z. Inst. xxi. (1889) 89; Kirk, Students' Fl. 343.
Var. angustatus.—Much less robust and more rigid, glabrous or sparingly clothed with short scabrid hairs. Leaves 1½–3 in. long, ¼–¾ in. broad, lanceolate or oblong-lanceolate, acute, all sessile or the lower sometimes petiolate, coriaceous, sharply and irregularly sinuate-serrate; veins usually prominent beneath.—S. Banksii var. scabrosus, Hook. f. Fl. Nov. Zel. i. 147. S. pumiceus var. angustatus. Kirk, Students' Fl. 343.
North Island: Mokohinou Island, Herb. Col. Mus.! Mercury Bay, Banks and Solander; East Cape Island, Ross; Anaura and Tolago Bay, Banks and Solander, Adams and Petrie! near Table Cape, A. Hamilton! between Tolago Bay and Gisborne, Colenso. Var. angustatus: East Cape, A. Hamilton; Karangahake Cliffs, Lake Taupo, T.F.C. Sea-level to 1500 ft. December–January.
Mr. Kirk limits S. Banksii to a form with more decidedly fiexuous stems and rather membranous glaucous leaves, keeping up Colenso's S. pumiceus for the reception of those states with stouter and sfcraighter stems and more coriaceous leaves. But a series of the Tolago Bay plant, which is that collected by Banks and Solander, shows that this distinction cannot possibly be maintained, some of the specimens exactly matching the types of S. pumiceus in Mr. Colenso's herbarium, while others show a regular gradation to more slender and membranous forms. An examination of the ripe achenes of both varieties also proves that the supposed difference in size and shape does not exist.
11. S. Colensoi, Hook. f. Fl. Nov. Zel. i. 147.—An erect much or sparingly branched herb 10–20 in. high, more or less clothed with white cobwebby tomentum. Stems woody at the base, flexuose, grooved. Leaves very variable, 1–4 in. long, ½–1½ in. broad, broadly oblong or obovate to lanceolate, obtuse or acute, sessile with broad amplexicaul bases or petiolate with auricles at the base of the petioles, coriaceous; margins sinuate-dentate or serrate or deeply irregularly lobulate or pinnatifid, hoary or cobwebby on both surfaces or on the lower surface only. Corymbs terminal, usually lax. Heads few or many, ⅓–½ in. diam., campanulate; involucral bracts linear-oblong, acute or acuminate. Eays short, revolute. Achenes slender, grooved, silky or hispid.—Handb. N.Z. Fl. 160; Kirk, Students' Fl. 342.

One of the finest species of the genus, well marked off from any other by a small portion of the very base of the leaf being pinnatifid or pinnate, all the remainder being dentate. The heads are sometimes as much as 2½ in. diam.
13. S. Kirkii, Hook. f. ex T. Kirk, Students' Fl. 344.—An erect perfectly smooth and glabrous branching shrub 6–12 ft. high; branches stout, brittle. Leaves very variable in size and shape, 2–5 in. long, ⅓–2 in. broad, lanceolate or obovate-lanceolate to oblong-ovate or rhomboid-ovate, acute or obtuse, entire or sinuate-dentate, rather fleshy, narrowed into a short slender petiole or cuneate at the base. Corymbs large, often much branched, 4–12 in. diam. or more; branches spreading; lower bracts foliaceous. Heads numerous, large, campanulate, 1½–2 in. diam.; involucral bracts in 2 series, linear-oblong, acute, margins membranous. Ray-florets few; ligules long, white, spreading, ¾–1 in. long.

Zel. i. 147, t. 39; Handb. N.Z. Fl. 161 (not of Linn. f.). Solidago arborescens, A. Cunn. Prodr. n. 435 (not of Forst.).
North Island: Common in hilly and wooded districts from the North Cape to Wellington. Sea-level to 2500 ft.
A very remarkable and beautiful species. The flower-heads are often so abundantly produced as to conceal the leaves, the multitude of snow-white rays then rendering the plant conspicuous from afar. In the northern forests it is often epiphytic on the distorted trunks of the rata (Metrosideros robusta).
14. S. myrianthos, Cheesem. in Trans. N.Z. Inst. vii. (1875) 348.—A small sparingly branched shrub 3–12 ft. high; bark black; branches slender, when young clothed with thin buff tomentum.

16. S. perdicioides, Hook. f. Fl. Nov. Zel. i. 149.—A small round-topped branching shrub 2–6 ft. high; branches slender, grooved, pubescent, scarred where the leaves have fallen away. Leaves 1–2 in. long, oblong or elliptic-oblong to ovate-oblong, obtuse, membranous, crenate-serrate or dentate, quite glabrous; veins reticulated; petioles slender. Corymbs leafy, terminating the branches; pedicels slender, pubescent. Heads turbinate, ⅓ in. long; involucral bracts about 5, oblong, obtuse, with broad scarious margins. Ray-florets 2 or 3, rarely more, yellow; ligule oblong, spreading. Disc-florets 4–8; limb funnel-shaped, deeply 5-lobed. Achenes oblong, grooved, glabrous or nearly so.

Panicle terminal, large, dense, much branched, 3–5 in. broad; pedicels slender, densely glan(iular-hirsute. Heads ½–¾ in. diam.; involucral bracts about 12, linear-oblong, obtuse or acute, membranous, glandular, villous at the tips. Ray-florets 15–20, yellow; ligule broad, revolute. Disc-florets numerous; limb campanulate, 5-lobed. Achenes oblong, grooved, glabrous. Pappus-hairs in 2 series, slender, scabrid.—Hook. f. Handb. N.Z. Fl. 734; Kirk, Students' Fl. 346.

Hekekopere Island (in Foveaux Strait): C. Traill, Kirk! The Snares: Kirk! December–January.
This is clearly identical with Armstrong's S. Stewartiæ, a name which has two years' priority over the S. Muelleri of Kirk. It is very closely allied to the preceding species, but the leaves are more acuminate, and the tomentum of tha under-surface is whiter, while the narrow contorted rays are quite unlike the short broad ones of S. Huntii.
19. S. laxifolius, Buch. in Trans. N.Z. Inst. ii. (1870) 89.—A small diffusely branched shrub 1–4 ft. high; branchlets, leaves beneath, and inflorescence densely clothed with white cottony tomentum.

Mr. Kirk has described the South Island plant as a distinct species under the name of S. viridis. It is somewhat larger in all its parts, but differs in no essential character, and is far better regarded as a variety only. Specimens of S. Bidwillii collected at the foot of Ruapehu by the Rev. F. H. Spencer almost match others gathered in the South Island by myself.

Fl. Atlant. ii. 228; Hook. f. Handb. N.Z. Fl. 165.
North and South Islands: Not uncommon throughout, ascending to 4000 ft. Dandelion. November–February.
A very variable plant. The large lowland forms, common in pastures or in rich cultivated soils, are probably introduced; but the small mountain state, with small leaves, slender scapes sometimes barely 2 in. high, and heads ⅓–¾ in. diam., is certainly indigenous, as it was collected by Banks and Solander.
26. SONCHUS, Tourn.
Erect leafy annual or perennial succulent herbs, juice milky. Leaves alternate or radical, entire or toothed or pinnatifid; cauline often amplexicaul. Heads peduncled, in terminal irregularly branched corymbs or panicles, homogamous. Involucre ovoid, usually becoming conical after flowering; bracts imbricated in several series, the outer smaller.
