 Stems often several from the same root, 1-2 feet high. Lower leaves 3-4 

 inches long, scarcely a line wide. Kays 5-6 lines in length, bright yellow : 

 disk brownish-purple. Achenia smooth; the wing of each side as broad as 

 the achenium itself: the awns or teeth minutely serrulate, somewhat ex- 

 ceeding the wing. — Differs from the Calliopsides with winged achenia only 

 in the more conspicuous teeth, and the entirely yellow rays. 



* * Ache?iia not incurved ; th£ margin serrulate, or with a lacerate or pcctinately dissected 

 wing. (Eublepharis &: Rhabdocaulis, Nutt., excl. spec.) 



22. C. glad'mta (Walt.) : glabrous; stem terete, striate, dichotomously 

 corymbose at the summit ; leaves somewhat fleshy, alternate, remote, en- 

 tire, or the upper ones frequently with two lateral lobes; the lowermost 

 oblong-lanceolate, sometinies 1-2-ternately-parted, tapering into a long mar- 

 gined petiole partly clasping at the base; the upper sessile, elongated hince- 

 olate or linear-lanceolate, riiostly acute; bracts alternate or opposite, subu- 

 late; scales of the exterior involucre ovate-lanceolate ; rays obovate, 3-lobed 

 at the summit ; achenia narrowly elliptical or somewhat obovate-oblong, 

 surrounded by a conspicuous pecti'nate fringe, crowned with 2 slender serru- 

 late-hispid awns about half the length of the corolla. — Walt.! Car. j). 215;

Sept. H Stem 2-3 feet high, naked above, 2-3 times dichotomous at the 



summit, and often bearing 9-12 heads on slender pedicels. Lower leaves, 

 including the petiole, often 6-10 inches long, somewhat veined : the upper 

 4-5 inches Ions, and deceasing upwards, 1-nerved: the uppermost rarely 

 opposite. Achenia glabious, or minutely papillose-scabrous, about twice the 

 length of the awns ; the linear segments of the fringed margin often as long 

 as the achenium itself is wide, appearing like a dissected wing. 



23. C. an"-usti/'olia (Ait.) : glabrous; stem acutely 4-angled, virgafe, slen- 

 der, dichotomously branched above ; leaves entire, opposite, or the lower fre- 

 quently alternate; the radical and lowest cauUne oblanceolate or spatulate, 

 tapering into a slender petiole; the others spatulate-linear, obtuse, narrowed 

 towards the base, sessile, the uppermost bract-like ; scales of the exterior in- 

 volucre ovate, obtuse ; rays obovate-cuneiform, 3-lobed at the summit, the 

 middle lobe largest; achenia elliptical, surrounded by a lacerate-fimbriate 

 ■wivg, crowned with 2 short upwardly hispid awns. — Ait.! Kew. [eel. I) 3.

 rather thick and opaque, often obscurely punctate; the cauline ones short 

 (1-2 inches long), and becoming smalle"^r towards the sunmiit; those of the 

 branches reduced to spatulate-linear bracts. Heads loosely dichotomous-
