almost hispid: calyx large, and nutlets ? line long, vitreous 
and shining, lineately rugose transversely and with or with- 
out murication. 
Frequent from northern California to Washington. Easily 
distinguished at sight by its large size, its many stems, and 
stiff harsh pubescence. 
LrrHosPERMUM LAXUM. Perennial, 1 to 14 feet high, as- 
cending or suberect, loosely and rather widely branched 
from near the base; herbage green, or very slightly canescent 
with an inconspicuous appressed pubescence: flowers small, 
greenish-yellow, in the axils of the leaves or large leafy 
bracts, these oblong-lanceolate, 14 inches long, the cauline 
leaves narrower and more elongated: nutlets large, ovate, 
abruptly obtuse-pointed. - 
West Humboldt Mountains, Nevada, collected by the au- 
thor in July, 1894, the plants at the time in both flower and 
fruit. Species somewhat intermediate between L. Califor- 
nicus and L. pilosum. 
ERr0coNUuM Preeri. Habit and inflorescence of E. flavum, 
nearly, but plant taller and scape slender, the whole herbage 
villous rather than tomentose, except the lower face of the 
leaf :’ leaves thin, the elliptic-lanceolate or oblanceolate blade 
an inch long or less, much shorter than the slender petiole ; 
whorl of leaves subtending, the umbel narrow and distinctly 
slender-petioled : umbel of 5 to 8 short equal rays: perianth 
greenish yellow, tipped with scarlet in age, hirsutely rather 
than silkily villous, and narrowed below to a long stipe-like 
base: achene woolly-hairy at apex. 
Blue Mountains of eastern Washington, at an altitude of 
about 5,000 feet. Readily distinguished from its eastern 
Rocky Mountain ally, E. flavum, by its different foliage and 
pubescence, and by the long slender stipe-like base of its 
perianth.
