38. D. Shuttleworthiana, Meissn. in Hook. Kew Journ. vii. 122. and in DC. Prod. xiv. 474. Apparently a low shrub, the leafy branches hoary-tomentose. Leaves narrow, 2 to 4 in. long, divided almost to the midrib into numerous contiguous obliquely-triangular lobes of 1 to 2 lines, all rather obtuse, rigid, with recurved margins, white underneath. Flower-heads almost sessile on the main stem below the leafy branches and without floral leaves, the very short peduncle covered with small or subulate and recurved scales. Involucre campanulate, the bracts narrow, mostly linear, very numerous, the inner ones 1½ in. long, recurved or reflexed from the middle, the long filiform ends usually ciliate with long fine hairs. Perianths 1 in. long or rather more, woolly-villous above the glabrous base, the limb very narrow, 3 lines long, glabrous. Style not exceeding the perianth, the stigmatic end scarcely distinguishable from the remainder. Capsule obovate, nearly ¾ in. long, densely rufous-villous.

39. D. speciosa, Meissn. in DC. Prod. xiv. 479. Branches erect, tomentose. Leaves very narrow-linear, mucronate-acute, quite entire, with closely revolute margins, 3 to 5 in. long. Flower-heads very large, nodding, terminating very short leafy branches but not closely surrounded by floral leaves, the very short peduncles covered by small scales. Involucre very broad and above 2 in. long, the bracts very numerous, linear with fine points at first elegantly ciliate with spreading hairs which wear off. Perianth 1¼ to 1½ in. long and therefore shorter than the involucre, woolly-hirsute above the short glabrous base, the upper half glabrous, the limb very narrow, 4 lines long. Style scarcely exceeding the perianth, the stigmatic end not distinguishable from the remainder.

40. D. tridentata, Meissn. in Hook. Kew Journ. vii. 120. and in DC. Prod. xiv. 479. Stems 6 in. to 1 ft. high from an underground creeping trunk. Leaves linear or linear-cuneate, mostly 3-toothed at the end, tapering into a very short petiole, 1 to 1½ in. long, flat, prominently reticulate underneath. Flower-heads large, on very short peduncles from below the foliage, leafless except a few narrow scales passing into the outer involucral bracts. Involucres broad, hemispherical, a few of the outer bracts leaf-like and longer than the flowers but mostly entire and dilated at the base, passing into ovate-lanceolate bracts with long narrow points and these again into the inner linear-lanceolate ones, the paleæ within the flowers few and very narrow. Perianths about 1 in. long, loosely villous, the limb narrow and acute. Style much longer, rarely quite straight, the slightly furrowed stigmatic end scarcely distinct. Capsule above ½ in. broad.
