8 to 9 lines long, silky-pubesccent. Anthers all perfect. Style-end scarcely thickened.

8. A. linearis, Meissn. in DC. Prod. xiv. 311. Apparently procumbent, with slender branching stems of above 1 ft., the young shoots silky-pubescent and hirsute with long fine hairs, the older foliage glabrous. Leaves entire, narrow-linear, obtuse, attenuate at the base, rather thick but flat, to 1⁄2 to 11⁄2 in. long. Involucres solitary or 2 or 3 together at the ends of the branches, on peduncles of about 1 line; inner bracts nearly 2 lines long. Perianth 6 to 7 lines long, softly hairy. Anthers all perfect. Style sparingly bearded, the end narrow-oblong.

9. A. sericea, Labill. Pl. Nov. Holl. i. 29. t. 38. A tall shrub or small tree of 10 to 20 ft., the branches and foliage softly silky-pubescent or villous with soft appressed or longer or spreading hairs. Leaves crowded, very shortly petiolate, twice ternately or pinnately divided into linear-terete almost filiform segments, often ending in small glabrous gland-like tips and sometimes the lower segments short, as if mutilated, with dilated almost peltate gland-like tips, the whole leaf 1 to l1⁄2 in. long, the floral ones often rather longer than the others. Involucres terminal, solitary or rarely 2 or 3 together, almost concealed by the foliage, on peduncles of about 1 line, the bracts silky-pubescent, the inner ones 2 lines long. Perianth above 1 in. long, silky-villous, slender, the laminæ densely bearded inside behind the anthers which are all perfect. Style glabrous, the end slightly thickened.—R. Br. in Trans. Linn. Soc. x. 152, Prod. 367; Meissn. in Pl. Preiss. i. 513, ii. 248, and in DC. Prod. xiv. 312; A. apiculuta, Meissn. in Pl. Preiss. i. 614, and in DC. l.c. 313, not of R. Br.

The specimens of Drummond's and Preiss's referred by Meissner to A. apiculata appear to me to be undistinguishable from the common A. sericea, except perhaps in the rather more rigid foliage with more spreading hairs, but even this distinction is very inconstant. I havc not secn in any of them the truly lateral gland at the ends of the leaf-segments as in the true A. apiculata, Br. (A. procumbens, Meissn.).
Var.? brevifolia. Leaves rather shorter but silky-villous and the perianth-laminæ densely bearded inside as in the typical A. sericea.—A. barbata, F. Muell. Herb.

The four following species may perhaps hereafter prove to be varieties only of A. sericea.
10. A. Meissneri, Lehm. Pl. Preiss. i. 512, ii. 248. A procumbent or irregularly spreading shrub of 3 or 4 ft., the branches pubescent or villous, the foliage hirsute pubescent or almost glabrous. Leaves mostly twice trifid but varying either more divided or less so, with terete rather rigid segments, more spreading than in A. sericea and
