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.,

* Root annual: style-tips almost truncate and with a short conical point : rays with some hrown- 

 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, al)0ve which are delicate 

 browuisli-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. & Grav,

* * Eoot apparently perennial: style-tips witli 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 squamellte. — 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 squamelire, which become subulate teeth, sometimes 

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



•4— 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 &
