294 PITTONIA. 
Telephone Cañon, and first distributed by him as E. decum- 
bens. It is a neat species, most related to E. plantagineus 
and Robertianus. 
E. Netsonu. Tufted stems 6 to 10 inches high, stout, 
ascending, striate; the short pubescence rigid and spread- 
ing but not coarse; linear-lanceolate radical leaves 2 or 3 
inches long, entire, 3-nerved; the cauline rather numerous 
up to the short peduncles, linear, acute, 1-nerved: heads 3 
to 6, on short stout peduncles and corymbose, or the stem 
rarely monocephalous; involucre broad-campanulate, its 
bracts rather short and merely acute, pubescent but not 
hispid, rather notably unequal: rays 35 or more, rather 
broad, purplish: pappus in a single series, but several short 
acute less scabrous bristles interspersed among the ordinary 
long ones. : 
Wyoming and Montana; the n. 859 of Prof. Nelson’s 
Wyoming plants, under E. corymbosus being typical. Ex- 
cept in the monocephalous state (in which it resembles E. 
canus) rather better meriting the name corymbosus than does 
the genuine thing; but very distinct from all others of this 
group by its stouter and more rigid habit, and the inequality 
of the bracts of the involucre which give to this a some- 
what imbricated appearance. 
E. MEMBRANACEUS. Near E. salsuginosus, and as large as 
the larger states of that species, but more slender and with 
ampler foliage, the leaves relatively broader, glabrous ex- 
cept along the margins, the whole texture very thin, and of 
a dark green: lowest leaves 6 inches long, the oblong- 
lanceolate blade longer than the petiole; the cauline 2 to 4 
inches, ovate-lanceolate or ovate, broad and spreading : 
heads about 3, on slender erect peduncles, and thus approxi- 
mate, not divergent: bracts of the involucre viscidulous, 
acuminate: rays about 30, bright blue, $ inch long or 
more,
