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

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

 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 : ra^'s with some brown- 

 puvple lines or spots toward Ilie base: leaves long-petioled. Transition to preceding section. 



C. coronata, Hook. Sparsely hirsute-pubesceut 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 obloug-lauceolate : rays an 

 incli or less long, bright yellow, with deeper or orange hue at base, above wliicli are delicate 

 brownisli-purplo markings, thus forming a sort of corona: akeues with a rather broad wiug 

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

* * 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 rhacliis) ; lowest cauline and radical petioled and tlie 

 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 : akeues 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 squamella;. — ArTiausas, on 

 cliffs near Fort Smith, Prof. F. L. Harvei/. 



* * * 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 ver}- large: pappus 

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

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



•y- 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 divi.sious 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 &

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