19. D. mucronulata, R. Br. in Trans. Linn. Soc. x. 213, Prod. 398. A shrub very closely allied to D. nobilis and D. formosa. Branches tomentose and villous. Leaves very long and narrow, with very numerous traingular-falcate rigid acute lobes which as in D. nobilis do not reach the midrib, all nearly flat and tomentose underneath. Flower-heads on very short axillary branches or almost sessile, surrounded by numerous floral leaves, smaller than in D. formosa. Outer involucral bracts ovate acuminate, the inner ones oblong-linear, obtuse, nearly 1 in. long and 2 lines broad, silky-villous. Perianths 8 to 10 lines long, woolly-villous above the glabrous base, the remainder silky-villous but the hairs not so long and fulvous as in D. formosa. Style under 1 in. long. Capsule nearly ¾ in. broad.—Meissn. in DC. Prod. xiv. 470.

20. D. formosa, R. Br. in Trans. Linn. Soc. x. 213, t. 3, Prod. 397. An erect shrub attaining 8 to 15 ft., the branches tomentose and often hirsute with long fine spreading hairs. Leaves 4 to 8 in. long, regularly divided to the midrib into obliquely triangular or broadly falcate segments, 2 to 3 lines long and broad, mostly acute, flat and not very thick, tomentose underneath. Flower-heads terminal, broad, surrounded by floral leaves longer than the flowers, the inner ones dilated at the base and passing into the involucral bracts. Involucre hemispherical, 1 to 1½ in. diameter, the outer bracts ovate acuminate, the inner ones narrow and obtuse, all tomentose-villous. Perianths 1¼ to 1½ in. long, woolly-villous above the short glabrous base, the remainder silky-villous, the limb narrow acuminate, about 2 lines long, densely villous, with long often fulvous hairs. Style scarcely longer than the perianth, with a narrow furrowed stigmatic end. Capsule about 5 lines long and 3 lines broad.—Meissn. in Pl. Preiss. i. 593 and in DC. Prod. xiv. 471; Sweet, Fl. Austral. t. 53; Bot. Mag. t. 4102.
W. Australia. King George's Sound, R. Brown, Fraser, Drummond, 3rd coll. n. 293, Preiss, n. 501, and many others. The flower-heads and flowers vary in size, even on the same specimens; some specimens from Barker and from Oldfield have them all smaller than usual. The capsules appear to be always small.
21. D. Baxteri, R.Br. Prot. Nov. 38. A shrub of 4 to 6 ft., the branches densely tomentose. Leaves very narrow, often above 1 ft. long, divided to the midrib into very numerous small triangular-falcate rigid acute segments, the largest scarcely 2 lines long and broad, all with recurved margins and white underneath. Flower-heads almost sessile in the axils, surrounded by long floral leaves. Involucre hemispherical, above 1 in. broad, densely ferruginous-villous, the bracts lanceolate, acuminate, the inner ones ¾ to 1 in. long. Perianths nearly 1 in. long, woolly near the base, then silky-villous, the limb 2 lines long, narrow, acute, tipped with a tuft of long fine hairs. Style ex-
