292 COMPOSITE. Coreopsis: 



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. Leachia, Cass. Diet, x., xxv.,

& Gray. 



* Root 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. Transiiion to preceding section. 



C. COronata, HOOK. Sparsely hirsute-pubescent or mainly glabrous, a foot or two high, 

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

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

 incli 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 : akeiies with a rather broad wing 

 and a pappus of 2 minute sipuamcllate teeth. Bot. Mag. t. 3400 (not L.) ; Torr. & Gray, 

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

 mental cultivation. 



* * Root apparently perennial: style-tips witli conspicuous cusps: rays sometimes brown-purple 

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



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

 above : leaves piuuately 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 laciuiate-dentate), mostly muricate-rougbened ; inner smooth and wingless or 

 nearly so ; callus small or none : pappus a pair of obtuse short squamellse. Arkansas, 011 

 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. grand.ifl.6ra, NUTT. Glabrous except the birsute-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 dhisions 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. Ilort. Barclay & 

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

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

 half-inch to inch long : foliage diverse. 



C. lanceolata, 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,

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



Var. angustifolia, TORR. & GRAY, I.e. (var. gktbella, 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. crassifoh'a, Ait.
