﻿This is very close to E. corymhosum and E. Thorn- 



To this species I would refer two specimens collected 

 by Rusby at Holbrook, Arizona, as var. gliitinositni, being 

 glutinous above; having oblong, crenate leaves, 2' long; 

 involucre somewhat angled; flowers smaller. 



To this species I would refer as var. ambigitum, No. 

 1688, Coville, collected on the east slope of the Sierras, 

 Inyo County, California, having narrow and entire leaves, 

 peduncles 4-6' long, small clusters of flowers and only 

 secondary and very short rays, the involucres much angled 

 and flowers very short, J^" long. 



No. 5036ao. April 12, 1894, "ear Hole in the Rock, 10 

 miles above Stone's Ferry, Nevada, in gravel, 1500- alt. 



No. 5036b]. April 12, 1894, 10 miles below Mica 

 Spring, Nevada, in gravel, 2000 alt. 



Annual, $-6' high; leaves radical, 10" long, and with a 

 slender petiole 1' long, the blade round or somewhat 

 oblate, truncate to cordate at base, and fully developed 

 ones emarginate at the apex; the younger leaves are very 

 white, with long, comose, tangled hairs, the upper side 

 less so or even green; inflorescence trichotomously 

 branched, mostly at the very base of the stem; small 

 bracts at least woolly within and with hyaline margins ; 

 involucres erect on pedicels i" long or less, over 1" high, 

 hemispherical, glaucous, with very short hyaline teeth; 

 flowers very small and exserted, %" long, pubescent with 

 rough, flat, short, scale-like hairs; flowers reddish or 

 greenish yellow, outer lobes elliptical, inner lanceolate 

 and barely acute ; stems and pedicels glabrous and flowers 



This is readily separable from E. Tkurberiby the leaves 

 and flowers and the more open and slender habit: it is
