starved form I have seen hanging from the cliffs, branching widely 

 and very pretty, and generally growing on rocks and occasionally 

 along vi\\h. Jajnesia Americana, a foot or two high. This form is 

 best represented by my specimens from Cheyenne Canon, near 

 Colorado Springs. The leaves are round and deeply cordate to 

 broadly ovate, always three-lobed above or below the middle, 

 lobes deep in some cases and scarcel}' recognizable in others, occa- 

 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 calj'x, 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 

 N. opulifoHa 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. alierfians, though should
