348 COMPOSlTiE. Coreopsis. 



whitish and somewhat cartilaginous smooth or ciliate-scabrous margin; the 

 lower ones mostly alternate, and tapering into a margined somewhat clasping 

 petiole, the uppermost much snialler, opposite, sessile; heads few; scales of 

 the exterior involucre oblong-linear, obtuse, scarcely half the length of the 

 interior; rays narrowly cuneiform, 3-lobed, 3-4 times the length of the in- 

 volucre; achenia (immature) narrowly cuneiform-oblong, wingless, the mar- 

 gin minutely ciliolate-hispid, crowned with 2 very short upwardly serrulate 

 awns. — Poir. sujyjd. 2. p. 252; DC. I j^Todr. 5. p. 570. C. (Emleri, Ell.

Carolina, Bosc! Georgia, "near the junction of Broad and Saluda Rivers, 

 Mr. CEmler" ex Elliott. Near Columbus, Dr. Boylcin ! and on the banks 

 of Spring Creek, Decatur County, in the same Slate, Dr. Clwpman ! — (1) ? 

 Stem 2-3 feet liigh. Lower leaves 3-5 inches long, with a petiole nearly 

 the same length, thick, rather acute at each end, with a conspicuous midrib, 

 obscurely feather-veined, varying in outline from ovate or oval to elongated 

 lanceolate; the upper shorter and often opposite, on short connate petioles.; 

 the uppermost reduced to bracts, always opposite. Rays bright yellow, 

 nearly an inch long. Corolla of the disk dark purple at the summit. 

 Branches of the style dark purple, terminated by a very obtuse or capitate 

 minutely hairy cone. Awns rather stout, scarcely one-fourth the length of 

 the immature acheniura. 



§ 4. Brandies of the style truncate or terminated with a very ohtuse cone: 

 achenia as in Coreoloma, or naked and xcingless : exterior involucre small: 

 rays 3-5-loothed, rose-red : the disk-jiowers light yellow : leaves alternate 

 or opposite^ undivided, and entire. — Cosmklla. 



25. C. nudata (Nutt.) : glabrous ; stem terete, dichotomously branched 

 above; leaves few and remote, alternate, terete, subulate ; the lower elon- 

 gated ; the upper very short; scales of the exterior involucre much shorter 

 than the interior; rays (rose-red) broadly cuneiform-obovate, crenately 

 3-5-toothed; achenia elliptical, surrounded with a narrow laciniately lace- 

 rate wing, crowned with two short upwardly fimbriaif^-serrulate awns. —

Near St. Mary's, West Florida, Baldwin. Apalachicola, Dr. ChajJman! 

 — 11 1 Stem 2-3 feet high, somewhat corymbosely branched, and bearing 

 3 to 6 or more showy heads on naked pedicels. Leaves, or rather petioles 

 without lamina, partly clasping at the base ; the lower ones (2-3) about 6 

 inches long, subulate-filiform; the uppermost reduced to minute tracts. 

 Rays showy, about 8 lines long. Lobes of the corolla of the disk puberulent 

 internally. Anthers brownish. Branches of the style yellowish, terminated 

 by a short, pubescent, rather acute cone. Awns scarcely exceeding the wing 

 of the achenium. — This plant resembles Cosmos in the color of the flowers, 

 and the section Coreoloma in the achenium and style, dichotomously corym- 

 bose heads, &c. The following species is a Calliopsis except in the color of 

 the flowers. 



26. C. rosea (Nutt.) : stem leafy, mostly branched ; leaves opposite, nar- 

 rowly linear, entire, obscurely 1-nerved, narrowed and slightly ciliate at the 

 base'; heads on short peduncles; exterior involucre very small; rays (pale 

 red, rose-color, or sometimes white) oblong, slightly 3-toothed ; achenia ob- 

 long, wingless, somewhat incurved when mature, and obscurely tuberculate 

 on the margins, crowned w-ilh an obscure truncate coroniform pappus. —
