S. petiolaris, var., Gray, PL Wright, i. 94. 5. Californica, var., Rothrock in Wheeler Rep. 

 vi 145. — S. W. Texas and New Mexico to Arizona ; same collectors. 



S. Lindheimeriana, Scheele. Obscurely pnberulent and glabrate, strict, more rigid, 

 especially the broadly lanceolate or oblong more acute and greener leaves : heads densely 

 glomerate in an ol)long spiciform thyrsus : involucre oblong-campanulate, its bracts more 

 unequal : akenes glabrous. — Linn. xxi. 599. «S. speciosa, var. rigidiuscula , Gray, PI. Lindh. 

 ii. 222, not Torr. & Gray. — Texas, on rocky bluffs and in exsiccated beds of streams, Lind- 

 heiiner, lleveichon. 



-1— -i— Southern Alleghaniau species: leaves thinner, mostly ample, bright green, tapering to 

 both ends, some of them acutely serrate: pubescence loose and somcwliat hirsute. 



S. Buckleyi, Tokr. & Gray. Stem 2 or 3 feet high, glabrous below : leaves ovate-oblong 

 to oblong-lanceolate (the larger 3 to G inches long) ; thyrsus loose and elongated, nearly 

 naked : heads 4 or 5 lines long, mostly pedunculate : bracts of the involucre narrowly oblong 

 with rounded-obtuse green tips: akenes glabrous. — Fl. ii. 198. — Lincoln Co., N. Carolina, 

 Curtis. Middle Alabama, Buckley. Jasper Co., Georgia, Porter. 



S. glomerata, Miciix. Mostly glabrous up to the inflorescence: stem stout, 1 to 3 feet 

 iiigh, leafy to the top: leaves ample, from oblong-ovate to lanceolate-oblong, acuminate (the 

 lower 5 to 12 inches long) : heads 5 or G lines long, in a leafy interrupted thyrsus, or often 

 in remote axillary clusters, all or most of them much .shorter than the subtending leaves : 

 involucral bracts oblong, obtuse: akenes glabrate. — Fl. ii. 117; Torr. & Gray, Fl. ii. 209. — 

 Moist wooded sides of the high mountains of Carolina and Tenn., especially Grandfather 

 and Roan. The well-developed inflorescence hardly ever glomerate, therefore the name of 

 tliis most marked species is misleading. 



S. Spithameea, M. A. Curtis. Stems a span to a foot high, roughish-pubescent, leafy to 

 the top : leaves glabrate; lower obovate-spatulate ; upper oblong (an inch or two in length), 

 acute: heads (barely 4 lines long) somewhat corymbosely glomerate at the summit, also (in 

 cult.) in low axillary clusters : involucral bracts acute or acutish : rays short, hardly surpa.ss- 

 ing the disk : akenes pubescent. — Gray in Am. Jour. Sci. xhi. 42 ; Torr. & Gray, Fl. ii. 208. 

 — Rockv summits of the higher mountains in N. Carolina, especially on Grandfather and 

 Roan ; first coll. by Curtis. 



^— ^— ^— Boreal and montane, of difficult and uncertain limitation: rays usually numerous. 

 ++ Bracts of the involucre acute. 



S. macrophyila, Pl-rsii. Glabrous or a little pubescent : stem stout, 8 inches to 3 or even 

 4 feet higli, leafy to or near the summit : leaves thin, ovate or the upper ovate-lanceolate, 

 acuminate, acutely serrate ; the lower (3 or 4 inches long) rounded at base or abruptly con- 

 tracted into a long winged petiole : heads (5 or 6 lines long) mostly pedunculate, few or loose 

 in the clusters, which in smaller specimens form a simple oblong or racemiform thyrsus, 

 and in the larger occupy the axils of many of the cauline leaves : bracts of the involucre 

 narrowly lanceolate-linear, thin and wlien dry somewhat scarious : rays rather long :ind nar- 

 row: akenes glabrous or rarely a little pubescent at summit. — Fl. ii. 542; Gray in Proc.

 Hudson's Bay, and Labrador. (Approaches S. Virgaurea, var. leiocarpa, of E. Asia.) 



S. multiradiata, Ait. Villous-pubescent above or glabrate, a span to a foot or so high : 

 leaves of ratlier firm texture and fine venation, minutely and sparingly serrate above, some- 

 times entire; cauline spatulate to lanceolate, all tapering gradually to sessile base, or the 

 radical into a slender margined petiole: heads (mostly 4 lines long) generally few and 

 glomerate in a single terminal roundisli or oblong compact often corymbiform cluster, occa- 

 sionally with one or two looser axillary clusters or brandies : bracts of the involucre nar- 

 rowly lanceolate, thinnish or thin-edged : rays numerous and narrow: akenes pubescent. —
