Sejiecio. COMPOSITE. 391 



S. aureus, L- Very early glahrate, usually quite free from wool at flowering (in spring or 

 early siiinnicr) and a foot or two high from small rootstocks : radical leaves mostly rounded 

 and undivided, and cauline lanceolate and pinnatifid or laciniate : most polymorphous species, 

 of which the typical form is bright green, 1 to 3 feet high, surculose by slender rootstocks : 

 leaves thin ; principal radical ones roundish, cordate or truncate at base, crcnate-dentate (1 to 

 3 inches in diameter), on long slender petioles; lower cauline similar, witli 2 or 3 lobelets on 

 the petiole, or lyrately divided or lobed ; others more laciniate-pinnatitid and lobes often 

 incised; uppermost sparse and small, with closely sessile or auriculate-dilated incised base: 

 heads rather numerous, 4 or 5 lines high : rays 8 to 12, conspicuous, rarely wanting : akenes 

 quite glabrous. — Spec. ii. 870 ; Michx. Fl. ii. 820 ;' Ell. Sk. ii. 331 ; DC. Prodr. vi. 432 ; Torr.

Var. obovatus, Tork. & Gray, 1. c. Kadieal leaves of thicker texture, rotund with 

 abrupt or truncate base, or obovate and cuneate-contracted into a short margined petiole, or 

 the earliest in the rosulate tufts almost sessile and humifuse : otherwise as in the typical 

 form. — 5. obovatus, Mulil. in Willd. Spec. iii. 1999; Pursh, 1. c. ; Ell. 1. c. S. EUiottii, 

 Torr. & Gray, Fl. ii. 443, a form with the early radical leaves more plantagineous and very 

 short-petioled. — More open and moist grounds, Canada to Indiana and (jleorgia, in the upper 

 country, characteristically developed southward. 



Var. Balsamitse, Torr. & Gray, 1. c. Less glabrate, not rarely holding more or 

 less wool until fruiting : depauperate stems a span or two, larger fully 2 feet high : principal 

 or earliest radical leaves oblong, sometimes oval, commonly verging to lanceolate, inch or 

 two long, serrate, contracted into slender petioles ; the succeeding lyrately pinnatifid : heads 

 usually rather small and numerous : akenes almost always hispidulous-pubescent on the 

 angles. — S. BalsamiUe, Muhl. 1. c; Pursh, 1. c. .S'. Phittcnsis, Nutt. Trans. Am. Phil. Soc.

 var. lanceolatus, Oakes in Hovey's Mag., &, Torr. & Gray, 1. c, an attenuated form of this, or 

 of the type, growing in shady swamps. S. pauperculus, Michx. Fl. ii. 120, depaujierate form. 



— Rocky or nearly dry ground, Canada to Texas, and northwestward to Brit. Columbia. 

 Var. compactus. A .span or two high, in close tufts, rather rigid, when young 



whitened with fine tomentum, glabrate in age : radical leaves oblanceolate or attenuate-spat- 

 ulate, entire or 3-toothed at apex, or pinuatifid-dentate, an inch or more long, thick and firm 

 at maturity ; cauline lanceolate or linear, entire or pinnatifid : heads rather numerous and 

 crowded in the cyme, rather small : ovaries papillose-hispidulous on the angles. — S. anrens, 

 var. horealis, Gray, PI. Wright, i. 125, & Proc. Acad. Philad. 1863, 68, in part. — N. W. 

 Texas ( Wright) to the base of the mountains in Colorado, Hall & Harbour, Greene, &c. ; 

 mostly in saline soil. 



Var. borealis, Torr. & Gray, 1. c. A foot down to a span high, at summit bearing 

 either numerous or few heads ; these not rarely rayless : leaves thickish ; radical from round- 

 ish with abrupt or even truncate base to cuneate-obovate and cuueate-spatiilate, half-inch to 

 inch long, slender-petioled ; cauline seldom much piunatifid : akenes glabrous. — 5. elongntus, 

 paucijlorus, & Cymbalaria? Pursh, Fl. ii. 529, 530. 5. aureus, var. foliosiis, &c., Hook. 1. c.

 Sierra Nevada in California, and mountains of Nevada, Utah, and Colorado, where are forms 

 undistinguishable from the following. 



Var. croceus, Gray, a span to a foot or two high, glabrous or early glabrate : 

 leaves somewhat succulent ; radical oblong to roundi.sh, sometimes lyrate ; cauline very 

 various : heads usually numerous in the cyme : flowers saffron-colored or orange, at least the 

 rays, or these sometimes wanting. — Proc. Acad. Philad. 1863, 68; Porter & Coulter, Fl.

 incised or sparingly pinnatifid: rays conspicuous. — 5. subnudus, DC. Prodr. vi. 428; Nutt.
