numerous corymbosely paniculate smaller heads: leaves (4 to 6 inches long) all lanceolate 

 and tapering to both ends, Ktssile by a narrow base (or the lowest oblong-spatulate and taper- 

 ing into a short petiole), usually with whole margin thickly serrate or serrulate with very 

 atute salient teeth : involucre oblong-campanulate, 20-30-flowered : ravs 5 to 8, oblong-linear, 

 sometimes fully half-inch long. — l-l. i. 3.32 (Torr. & Gray, Fl. ii. 441, as to name only, the

 to Idaho and S. Colorado ; first coll. by Duurjlas. The form with the very serrate leaves of 

 the original of Douglas, but with much fewer and larger heads, mountain.? of Colorado, 

 Fremont, Hall & Harbour, Parry, Rothrock (under 5. Andinus). I'asses into 



Var. integriusculus. Heads smaller (usually only 3 or 4 lines high) and narrower, 



fewer-flowered : lea\"es minutely serrate or denticulate, or the upper entire, sometimes all 

 entire or nearly so, generally shorter and smaller, or broader and not acuminate. — S. Andinus,

■^-^ •^+ -t-i- ++ Stem not numerously but somewhat equably leafy up to the inflorescence ; leaves 

 all entire or denticidate: involucre fleshy-thickened! 



crassulus, Gray. A foot or less high, glabrous apparently from the first : stem rather 

 stout, 5-7-leaved, bearing 3 to 8 pedunculate rather large (fully half-inch high) and thick 

 heads ; leaves oblong-lanceolate, of rather firm texture, apiculate-acute, 2 to 5 inches lung ; 

 radical and lowest cauliue spatulate or obovate-oblong, narrowed into a short winged petiole; 

 upper sessile by partly clasping or rtecurrent base : involucre broadly canipanulate, 40-50- 

 flowered, of 12 or more lanceolate to oblong fle>hy-thickened but thin-edged bracts, the base 

 also much thickened, the whole becoming conical and multangular in fruit : rays about 8, 

 oblong. — Proc. Am. Acad. xix. 54. 5. integerrimus. Gray, Am. Jour. Sci. 1. c, & Proc.

++ -H- -w- -H- -H- Strms either few-leaved or with the upper leaves (and f^ometimes most of the 



cauline) reduced in size; the inflorescence therefore naked: none with narrow linear leaves 



(except one seapose specie-!-). 

 ^ Plant tall and simple-stemmed, with a coarsely fibrous cluster of roots, perhaps not perennial : 



leaves fleshy-coriaceous, all entire or barely denticulate. 

 S. hydroptlilus, Nctt. A'ery glabrous and smooth, sometimes glaucous: stem robust, 

 2 to 4 feet high, strict: leaves lanceolate, with strong midrib and obsolete veins; radical 

 oblanceolate and stout-petioled, sometimes a foot long and nearly two inches wide; upper 

 cauline sessile or partly clasping : heads numerous in a branching corymbiform cyme, 

 5 lines high, short-pedicelled : involucre narrowly campanulate, slightly bracteolate ; its 

 bracts 8 to 12: disk-flowers 15 to 30; rays 3 to 6 and small, sometimes none. — In water or 

 verv wet ground, especially in brackisli water, Montana to Brit. Columbia, south to Colo- 

 rado, and w e.--t to .San Francisco Bay, California. 



— = Plants mostlj- in clumps or tufts, or from tufted or creeping rootstocks. 

 a. Stems commonly robust, from a foot or rarely le?5 to 3 or even 5 feet high, bearing mostly 



numerous headsin a cyme: iiivcducre sparingly calyculate: leaves from entire to dentate, only 



in the last species at ail laciniate, none really cordate nor with permanent tomentum. Western 



species, none truly alpine. 

 1. Glaucous or glaucescent, apparently quite glabrous throughout from the very first: heads 



many-flowered. 

 S. Clevelandi, Greene. Stems rather rigid and slender, a foot or two high from firm 

 'creeping rootstocks: leaves subcoriaceous, entire, obtuse, with veins almost obsolete, spat- 

 ulate or rarely obovate; radical and lower cauline an inch or two long, tapering into 

 much longer .slender petioles ; upper cauline few and smaller, with shorter petiules : heads 

 4 or 5 lines high : involucral bracts subulate-linear : rays 6 to 8 and short, sometimes fewer, 

 occasionally none. — Bull. Torr. Club, x. 87. — Spriugy ground, Lake Co., California, Cleve-
