(1214.) P. palmata, Gray. Low swampy places from Morley, 

 westward through the Eockies, to the Selkirk summit ; always in the 

 subalpine valleys. (^Macoun.) 



Var. frigida, Macoun. A form intermediate between this species 

 and the next was collected on the highest summits of the Eockies, at 

 Kicking Horse Lake, and also at the summit of the Selkirks on Glacier 

 Mountain. In both cases it was close to perpetual snow and never 

 seemed to connect with the common form in the valley. The leaves, 

 although bearing a general resemblance to those of P. palmata, have no 

 sinus at the base, but the blade passes into the petiole.

 Eocky and Selkirk Mountains, Lat. 51°. (Macoun.)

 the Eocky Mountains, to Donald in the Columbia valley. Seldom in 

 the higher mountain woods. (Macoun.) Thickets along the Thompson 

 Eiver at Spence's Bridge, B.C. (^Fletcher.)
