35. D. horrida, Meissn. in DC. Prod. xiv. 476. Branches thick, hoary-tomentose. Leaves crowded, narrow, 3 to 6 in. long, pinnatifid, the lobes distant, rigid, pungent-pointed, 1½ to 3 lines long, divaricate or incurved, the margins of the lobes and of the narrow rhachis closely revolute, the under surface hoary or white where open. Flower-heads axillary, closely surrounded by long floral leaves. Involucre narrow ovoid, the bracts linear or a few of the shorter ones lanceolate with long points, all villous with rather long soft hairs, the inner ones 1½ in. long, but the upper half reflexed when the flowers are open and falling away soon after. Perianths 1¼ in. long, shortly woolly-villous above the glabrous base, the limb narrow, 3 lines long, glabrous as well as the upper part of the tube. Style longer than the perianth, with a long stigmatic end scarcely distinguishable from the remainder.

36. D. serratuloides, Meissn. in Hook. Kew Journ. vii. 123. and in DC. Prod. xiv. 475. Branches hoary-tomentose. Leaves crowded, 2 to 3 in. long, deeply pinnatifid but not quite to the midrib, the lobels linear-lanceolate, often falcate, rigid and pungent-pointed, nearly flat, pale or scarcely white underneath, 2 to 4 lines long. Flower-heads axillary, closely surrounded by floral leaves. Involucre broadly ovoid or almost globular, about ¾ in. long, the bracts lanceolate or the outer ones ovate, obtuse, appressed, at first minutely ciliate, at length glabrous and smooth. Perianths about 1 in. long, silky-hairy except the glabrous base, and the hairs of the limb fewer and deciduous. Style considerably longer than the perianth, the stigmatic end not thicker but darker coloured and furrowed.

37. D. comosa, Meissn. in DC. Prod. xiv. 478. Branches slightly tomentose, Leave 6 in. to above 1 ft. long, very narrow, rigid, flexuose, bordered by small pungent-pointed distant teeth or lobes, 1 to 1½ lines long, the margins of the teeth and rhachis revolute, leaving a narrow white under surface or channel between them and the broad midrib. Flower-heads axillary, with a few long floral leaves round them. Involucre broadly ovoid, 1¼ to 1½ in. long, the outer bracts ovate with short points, the inner ones lanceolate to linear, acute or the innermost almost obtuse, all glabrous or the margins minutely ciliate. Paleæ of the receptacle very slender but longer than in most species. Perianth-tube ¾ in. long, villous in the upper part of the undivided base, the limb narrow, about 2 lines long, silky-hairy. Style exceeding the perianth, the stigmatic end not thicker, but slightly furrowed.

Series 7. Gymnocephalæ.—Flower-heads lateral, on very short scale peduncles without floral leaves outside the involucre. Involucral bracts very numerous and narrow, a few of them leaf-like in one species.
