starved form I have seen hanging from the cliffs, branching widely 
and very pretty, and generally growing on rocks and occasionally 
along with /amesia Americana, a foot or two high. This form is 
best represented by my specimens from Cheyenne Cafion, near _ 
Colorado Springs. The leaves are round and deeply cordate to 
‘broadly ovate, always three-lobed above or below. the middle, 
lobes deepin some cases and scarcely recognizable in others, ccca- 
sionally five to seven-lobed but less distinctly so, three-nerved or 
five-nerved on the same plant as it happens, digitately (as 
described in the beginning of this article), half an inch or less 
long, rather thin and almost glabrous; corymbs in my specimens 
never proliferous, glabrous or stellate-pubescent, ten to twenty 
flowered, petals one and one-half lines long and_ scarcely 
exceeding the sepals or lobes of calyx, flowers small. Another 
specimen from the same locality has leaves twice as large as well 
as flowers, and corymbs compound at base. This differs from 
NV. opulifoka only in the monogynous ovary and slightly inflated 
pod, more incised and less pubescent leaves, and smaller size. 
Other specimens from the foothills are more robust and the most 
vigorous leaves are often quite acute and long-ovate. Utah 
forms seem to be rare. I have never found it in Utah, though 
I collected a peculiar form in the Schell Creek Mountains, 
Nevada near the western edge of Utah. This is a low, densely 
branched shrub with leaves one-fourth to one-half an inch long 
nearly round and usually cordate at base, always very obtuse, 
seldom more than three-lobed, but doubly crenate with the 
incisions very irregular, densely and often ferruginously 
pubescent on the nerves below and softly so all over, but upper 
surface less so; flowers very small, three to ten and about 
umbellate; petals not longer than lobes of calyx which are 
obscurely lacerate and hyaline on the margins, more so than in 
the smallest form of the type; stamens about twenty and the 
alternate ones one-half shorter, the larger ones with much 
dilated base; anthers oval and as in the type attached by the 
middle and apparently without a bloom while the type has a 
decided bloom and is oblong oval; style simply two-lobed at 
apex: Such marked characters would ordinarily be regarded as 
Specific, but I prefer to call it var. al/ernans, though should
