with few rather long linear segments, narrow but flat or concave and mostly obtuse, the whole leaf 1 to 2 in. long including the short petiole. Involucres solitary in the axils, on peduncles of 2 to 3 lines. Bracts acute, silky-hairy, the inner ones 2 lines long. Perianth about 1 in. long, silky-villous, the tube straight. Anthers all perfect. Style-end slender.
W. Australia. King George's Sound, Fraser; in the interior, Preiss, n. 2621 {Meissner). I have not seen Preiss's specimen; all others, which I have seen in different collections, appear to have originated in a shrub raised in the Sydney Botanic Garden from Fraser's seeds.
5. A. pungens, Meissn. in Pl. Preiss. i. 515, ii. 248, and in DC. Prod. xiv. 318. A rigid bushy or spreading shrub, the young shoots hoary-tomentose, the adult foliage glabrous. Leaves terete, slightly grooved above, entire or divaricately bifid or trifid above the middle, rather thick, rigid and pungent-pointed, 3⁄4 to 11⁄2 in. long. Involucres solitary in the upper axils, sometimes rather crowded towards the ends of the branches, on peduncles of 1 to 2 lines. Bracts softly silky-villous, the inner ones about 11⁄2 lines long. Perianth rather under 1 in. long', silky-villous. Anthers all perfect. Style slightly hairy, the end scarcely thickened. Fruit oblong, 2 to 3 lines long.—A. armata, Meissn. in DC. Prod. xiv. 313.
W. Australia, Drummond, 3rd coll. n. 256 (with the leaves mostly, but not all, undivided), 5th coll. n. 400 (with the leaves mostly, but not all, 3-fid); in the interior, Preiss, n. 671 {Meissner). Meissner distinguishes A. armata from the divided-leaved specimens of A. pungens, by the leaves divided to below the middle and by the laminæ of the perianth-segments longer in proportion, neither of which characters holds good in our specimens, all from Drummond; I have not seen Preiss's.
6. A. venosa, Meissn. in DC. Prod. xiv. 311. A bushy shrub of 3 or 4 ft., the branches and young shoots softly and often densely villous, the older foliage nearly glabrous. Leaves crowded under the flowers, more distant along the branches, sessile, entire, obovate or broadly elliptical, shortly acuminate or mucronate-acute, narrowed at the base, often ciliate on the margins, 1⁄2 to 3⁄4 in. long, often coriaceous, more or less prominently marked with almost longitudinal veins, the floral ones often rather larger than those below them. Involucres in terminal clusters or umbels of 3 to 6, rarely solitary, on short peduncles; bracts 4 to 6. Perianth about 1 in. long, slender, glandular-hirsute. Anthers all perfect. Style-end scarcely thickened.
W. Australia, Drummond, 4th coll. n. 264; in the interior from Cape Le Grand and summit of W. Mount Barren, Maxwell.
7. A. Dobsoni, F. Muell. Fragm. vi. 204. A prostrate much-branched shrub, spreading to 1 or 2 ft. diameter, the young shoots silky-hairy, the older foliage glabrous. Leaves entire, oblong—linear or spathulate, mostly under 1⁄2 in. long, very obtuse, narrowed into a distinct petiole. Involucres terminal, solitary, on very short peduncles; bracts obtuse, the inner ones about 11⁄2 lines long, Perianth slender,
