separated by broad sinuses, with revolute margins, white underneath. Flower-heads rather large, terminal, surrounded by numerous long floral leaves ciliate at the base with long spreading hairs. Involucre ovoid, above 1 in. long, the bracts numerous, oblong-lanceolate or the inner ones almost linear, nearly glabrous except the densely ciliate margins. Perianths 1¼ in. long, the undivided glabrous base longer than in most species, the remainder loosely villous. Style nearly 2 in. long, with a small narrow dark-coloured stigmatic end.—Meissn. in Pl. Preiss. i. 595, and in DC. Prod. xiv. 475; Bot. Mag. t. 4035.
W. Australia. King George's Sound or neighbouring districts, Baxter, Drummond, 5th coll. n. 418; Mount Manypeak, Preiss, n. 515.
Var. tortifolia. Leaf-lobes narrower and more rigid, not so white underneath.—D. tortifolia, Kipp. in Hook. Kew Journ. vii. 121; Meissn. in DC. Prod. xiv. 475.—Between Moore and Murchison rivers, Drummond, 6th coll. n. 211. A specimen of Drummond's 3rd coll. suppl. n. 101, is intermediate as it were between this and the typical form as to foliage, but is not in flower.
24. D. nana, Meissn. in Hook. Kew Journ. vii. 121. and in DC. Prod. xiv. 475. A dwarf or creeping shrub with the habit of D. nivea. Leaves 2 to 4 in. long, crowded round the flower-heads on very short ascending stems, divided almost to the midrib into linear-lanceolate acute lobels, all very spreading and often falcate, 2 to 3 lines long, the margins not revolute, scarcely white underneath, with prominent primary veins. Involucre closely sessile within the leaves, ovoid, under ½ in. long, the bracts narrow-lanceolate, silky-villous, the outer ones with subulate points, the inner ones acute. Perianths with the entire base about ½ in. long villous towards the end, the divided portion of the tube about as long, the limb ovoid, reflexed before opening, slightly hairy. Style hairy, very long, doubled down to the limb until released, and then straightening to a length of about 3 in., with a large thick ovoid stigmatic end.
W. Australia. Near Dundaragan, Drummond, 6th coll. n. 210. With the habit of the Niveæ, this species has a somewhat different foliage, and differs from the whole genus in the remarkable style.
25. D. Preissii, Meissn. in Pl. Preiss. i. 599, and in DC. Prod. xiv. 480. A dwarf shrub with short procumbent stems tomentose and with linear-lanceolate scales on the base of each year's growth. Leaves rarely above 6 in. long, pinnate; segments numerous, linear, acute or mucronate, rigid, with revolute margins, entire or pinnatifid, the larger ones above 1 in. long, but often all under ½ in., tomentose underneath. Flower-heads terminating the short ascending stems, with a few long floral leaves round them. Involucre ovoid, about 1 line long, the bracts numerous, all narrow, the outer ones with a short broader base and long subulate ends, the others linear or linear-lanceolate, flat and rigid, glabrous or loosely tomentose. Perianths about 1 in. long, loosely hirsute, the tube very slender, the limb broader, about 1 line long. Style 1¼ in. long, the stigmatic end small, narrow-conical. Fruit unknown.
W. Australia. Drummond, 2nd coll. n. 301; Gordon river, Preiss, n. 528; Stirling range and Hay river, F. Mueller. This species is placed next to D. bipinnatifida
