Alleghanies of Penn., Poiin- and Traill Green, seems to he a depauperate form of the present 

 species, with stem naked and leafless except uear the base, aud bristly liair.s uot so long; 

 but heads in the specimens barely in blossom, and al^eues uukuowu. ") 



# * Kocky Mountain and Pacific species. (Involacre in most cases less obviously double than in 

 tlie Eastern species; tlie calyculate bracts sometimes unequal or emulating tlie interior, or else 

 obsolete.) 



+- Crinite-hirsute with long and whitish or yellowish shaggy denticulate hairs, especially on both 

 sides of the entire leaves, on tiie branching leafy stems and panicle, and commonly but not 

 ahvays on the involucre also: flowers yellow: akenes columnar and short, not at all narrowed 

 upward, at most a line and a halt long, shorter than the sordid pappus.

H. KELfctxuw, Fries, Epicr. l;j.3, would seem to be only a taller and simpler-stemmed

 a specimen in herb. DC, from mountains of California, Bridges. 



^_ ^_ Crinitely long-villons wifli soft-woolly and blackish smooth hairs, which involve the heads, 



&:c.. but are wanting to lower leaves ; no stellular pubescence ami no glands: flowers yellow: 



pappus fuscous. 

 H. triste, Cii-iii. A span or two high : stem simple, few-leaved, bearing solitary or mostly 

 2 to 4 somewhat racemosely disposed heads : radical leaves obovate to spatulate, entire, 

 green and glabrate, or with sparse pale hairs; cauline oblong, upper ones and stem more '<t 

 less villous-lanate : heads half-inch high : livid involucre and peduncles densely clothed with 

 the very long dark-brown or partly grayish soft wool : akenes short-columnar. — Cham, in

(but glabrous or at most puberulent) : flowers yellow : pappus sordid. 

 H. gracile. Hook. Pale green, in tufts : leaves nearly all in radical clusters, obovate- to 

 "oblong-spatulate (1 to 3 inches long) and attenuate into petioles, entire or repand-denticn-
