62 . MEMOIRS FROM THE DEPARTMENT OF BOTANY OF COLUMBIA UNIVERSITY 
Intnusrrations: Pxare 20, f. 1; dissection of flower, f. 2; pistil, f. 3; stamens f. 4; 
fruiting hypanthium and calyx, f. 4. 
Low and subcespitose ; stems less than 1 dm. high, when young slightly villous, 
elabrate in age. Stipules ovate, acute. Basal leaves pinnately rather than palmately 5- 
foliolate, thick and somewhat coriaceous, with ribs prominent beneath ; leaflets obovate 
in outline, the two lower much smaller, all deeply cleft into oblong divisions and 
more or less decurrent, especially in the type specimens. Hypanthium silky-villous, in 
fruit about 5 mm. in diameter. Bractlets oblong, obtuse, much shorter than the ovate- 
lanceolate acute sepals. Petals obeordate, much longer than the sepals. 
This species much resembles the preceding, especially the var. glaucophylla, but it is 
a more cespitose plant and has smaller and thicker leaves with prominent veins beneath. 
The leaflets are generally five and the lower often attached a little lower down and de- 
current on the petiole, but this is not always the case by far. It is found in the higher 
mountains of Utah, Wyoming, Montana and British America.

petioles. Stems ascending, 1-3 dm. high, glabrate or slightly pubescent, 2-4-flowered and few-leaved. 
Basal leaves digitately 5-foliolate, thin, not strongly veined, glaucous, glabrous or ciliate ; leaflets ob-
