also been collected by Dr. Blankinship in Montana and in Yellowstone park, 
but I am unable to cite his numbers. 
Epilobium Wyomingense.—Perennial, spreading by filiform 
remotely scaly subterranean shoots which end in ovoid winter 
bulblets with few fleshy scales: stems slender, 2-4 high, 
strictly erect, mostly simple, more rarely with slender, erect 
branches from the axils of the opposite leaves; wholly glabrous 
below, towards the summit of stems and branches (if any) am 
obscure puberulence: leaves thin and glabrous, linear, tapering 
from the middle to both ends, sub-acute, from 3—-5™ long (rarely 
even 8™ long), 2-5™" broad, the uppermost not noticeably 
reduced, midrib evident, the lateral veins obscure, plane, oF the 
margin barely revolute, opposite except the floral, the few (4-7) 
pairs nearly equidistant, often shorter than the internodes ; those 
of the branches similar: flowers several, erect, small; the calyx 
cleft nearly to the base; the petals white, ovate, deeply triangu 
lar-notched at apex, 3-4™™ long, a little longer than the sepals: 
capsules linear, 4-7 long, minutely cinereous-puberulent; th 
pedicels variable, from much shorter to even exceeding the nail 
sule: stigma oblong or short-clavate, barely notched at ape*: 
seeds numerous, fusiform, smooth, scarcely beaked; the com 
white, persistent. 
This species is not very closely allied with any of the species re 
me, though in a few respects it suggests . Oregonense gractllimin” 
Slaberrimum. In the more essential characters it seems to be evn 
palustre, from which its longer smooth leaves and smooth stems an 
smooth almost beakless seed separate it. +o gtreall

It occurs in dense patches, on the grassy, boggy banks of SP Snake
