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



S. Lindheimeriana, SCHEELE. Obscurely puberulent and glabrate, strict, more rigid, 

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

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

 unequal : akenes glabrous. Linn. xxi. 599. S. speciosa, var. rigidiuscula, Gray, PL Lindh.

-I- H- Southern Alleghanian species: leaves thinner, mostly ample, bright green, tapering to 

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



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

 to oblong-lanceolate (the larger 3 to 6 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, MICHX. Mostly glabrous up to the inflorescence: stem stout, 1 to 3 feet 

 high, 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 : 

 iiivolucral bracts oblong, obtuse: akeues 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 

 this most marked species is misleading. 



S. spitlmmasa, 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 : iuvolucral bracts acute or acutish : rays short, hardly surpass- 

 ing the disk : akeues pubescent. Gray in Am. Jour. Sci. xlii. 42 ; Torr. & Gray, Fl. ii. 208. 

 - Rocky summits of the higher mountains in ]S T . Carolina, especially on Grandfather and 

 Roan ; first coll. by Cuitis. 



+- -i -) Boreal and montane, of difficult and uncertain limitation : rays usuallv numerous. 



H- Bracts of the involucre acute. 



S. macroph^Tla, PCRSH. Glabrous or a little pubescent : stem stout, 8 inches to 3 or even 

 4 feet high, 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 cauliue leaves : bracts of the involucre 

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

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

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

 leaves of rather 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 iu a single terminal roundish or oblong compact often corymbiform cluster, occa- 

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

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