292 composite. 



as also the aisk-flowers : narrow chaffy bracts of receptacle attenuate-filiform at 

 apex : heads usually showy, on long and simple peduncles : leaves all opposite, 

 entire or pinnately 3-7-parted, mostly petioled. — LeacMa, Cass. Diet, x., xxv., 

 lix. Coreopsides, Mcench. Ghrysomelea, Tausch. § Eucoreopsis, LeacMa, Torr. 

 & Gray. 



# Eoot annual : style-tips almost truncate and with a short conical point : rays with some brown- 

 purple lines or spots toward the base : leaves long-petioled. Transition to preceding section. 



C. Coronata, Hook. Sparsely hirsute-pubescent or mainly glabrous, a foot or two high, 

 lax : leaves entire or the lower 3-5-parted, obovate and spatulate-oblong, the lateral divisions 

 when present small : bracts of the outer involucre lanceolate or oblong-lanceolate : rays an 

 inch or less long, bright yellow, with deeper or orange hue at base, above which are delicate 

 brownish-purple markings, thus forming a sort of corona : akenes with a rather broad wing 

 and a pappus of 2 minute squamellate teeth. — Bot. Mag. t. 3460 (not L.) ; Torr. & Gray, 

 Fl. ii. 345. — E. Texas, Berlandier, Drummond, Lindheimer, &c. Rather common in orna- 

 mental cultivation. 



# # Eoot apparently perennial: style-tips with conspicuous cusps: rays sometimes brown-purple 

 at base : heads small : cauline leaves hardly petioled, very slender. 



C. Harveyana. A foot or more high, smooth and glabrous : stems slender, branching 

 above : leaves pinnately parted into 3 to 7 and upper often palmately parted into 3 to 5 

 filiform divisions (no broader than the rhachis) ; lowest cauline and radical petioled and the 

 divisions narrowly linear : involucre about 3 lines high : bracts of the outer involucre nar- 

 rowly lanceolate-linear, little shorter than the inner : rays 3 or 4 lines long ; disk-flowers 

 brownish in age : akenes orbicular (only a line long), outer narrowly winged (and the wing 

 occasionally laciniate-dentate), mostly muricate-roughened ; inner smooth and wingless or 

 nearly so ; callus small or none : pappus a pair of obtuse short squaniellai. — Arkansas, on 

 cliffs near Fort Smith, Prof. F. L. Harvey. 



# # * Eoot perennial, or in the first species sometimes annual: rays yellow throughout (the 

 larger inch long) : style-tips with conspicuous cusp : calli of the akene often very large : pappus 

 a pair of small denticulate or fimbriolate squamella?, which become subulate teeth, sometimes 

 deciduous or obsolete ; at least lower leaves slender-petioled : species apparently confluent. 



+- Wings of the akene thin-scarious, outspread, broad when well developed. 



C. grandiflora, Nutt. Glabrous except the hirsute-ciliate petioles, rarely sparsely pilose, 

 a foot or two high : radical and some lower cauline leaves lanceolate or spatulate and entire ; 

 upper or sometimes all the cauline 3-5-parted or divided, the divisions lanceolate or linear, 

 or even almost filiform, sometimes again 2-3-parted : heads, &c, nearly of the next, usually 

 larger : akenes with more conspicuous squamellate or paleaceous pappus. — Hort. Barclay & 

 Trans. Am. Phil. Soc. vii. 358; Sweet, Brit. Fl. Gard. t. 175; DC. Prodr. v. 572; Torr. & 

 Gray, Fl. ii. 344, with the vars. longipes & subintegrifolia. C. longipes, Hook. Bot. Mag. t. 3586 ; 

 DC. 1. c. 0. Boykiniana & C. heterophylla, Nutt. Trans. Am. Phil. Soc. 1. c. — Low grounds, 

 Georgia to S. Missouri and Texas. Variable species : involucre 5 to 7 lines high : rays 

 half-inch to inch long : foliage diverse. 



C. lanoeolata, L. Low, only a foot or two high, including the long and simple naked 

 peduncles : leaves ordinarily a few pairs, oblong-spatulate to lanceolate or nearly linear, ob- 

 tuse, thickish, all entire, or rarely 1 or 2 small lateral lobes : rays commonly inch long and 

 half -inch broad, sometimes smaller : pappus very small or obsolete. — Spec. ii. 908 (Martyn, 

 Hist. PI. t. 26; Dill. Elth. t. 48) ; Michx. Fl. ii. 136; Torr. & Gray, Fl. ii. 344. LeacMa 

 lanceolata, &c, Cass. Chrysomelea lanoeolata, Tausch. — In rich or sandy damp soil, W. Can- 

 ada and Illinois, Virginia, &c, to Florida and Louisiana. The ante-Linnsean figures well 

 represent the species ; the type glabrous or nearly so, except hirsute ciliation : passes into 



Var. angUStifolia, Torr. & Gray, 1. c. (var. glabella, Michx. 1. c, partly) ; a low 

 form, with narrow leaves (2 to 4 lines wide) all crowded on the abbreviated stems, and scapi- 

 form peduncles about a foot long. — Shore of L. Superior to Florida. 



Var. villosa, Michx. 1. c. Leaves spatulate-obovate to oblong-lanceolate or oblong, 

 villous-hirsute with many-jointed hairs, as also lower part of the stem. — C. erassifolia, Ait.
