Ei Wasatchense. 



Stems shortly produced, 1-2 inciics long, densely leafy, leaves 

 narrowly elliptical, greener alxivc. with crimped edges, about 1-1^2 

 inches long ; petioles short ; peduncles about 1 foot long, repeated- 

 ly 3-forked at the end into a narrow and paniculate 

 corymb with moderately unecnial rays : involucres single, nearly 

 sessile in the forks and sessile on the ends of the slender ulti- 

 mate branches, 2-2}''> lines long, campanulate, bluntly and scar- 

 iously to<:»thed, scarcely angled above, like the c(innate bracts in 

 being ciliate-woolh on the margin ; flowers white. 1 line long. witFi 

 oblong sepals. This is close to E. Jiatemani. 



E. Batemani. 



Leaves oblong-elliptical, triangular at tip. leathery, nearlv 

 equally pubescent on both sides, on a short and stout petiole nearlv' 

 half the blade; stems densely clustered at the top of the ground 

 and leaves fasicled there, rather stout ; pediuicles about 6 inches 

 long where they branch into their unequal and slender rays, tlie 

 longest of which nearly equal the peduncle, these again branch into 

 2-3 nearly tiliform raylets which are 2-4 inches long and widely 

 spreading, and with a single involucre, mostly sessile in the forks, 

 the raylets tipped with about 2 sessile involucres ; campanulate in- 

 ^■olucrcs 2 lines long, nearh" smooth, not angled, apparently acutely 

 toothed, but the acute green portion is really very obtuse by being 

 broadh- and scariously margined; flowers few, white: sepals white, 

 smooth, barely united below, oblong and barely enlarged at tip. 

 3-4 lines long ; bracts minute, united into a flat disk which is 3- 

 angled. hyaline margined and toothed. Price, Utah, on clayey
