(1200.) A. discolor, Dougl. Common on the sides of ravines at 

 the Kananaskis and grassy slopes of Castle Mountains, Eocky Moun- 

 tains ; also on the slopes of the Sol kirks, at the summit, B.C. (Macoun.)

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

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

 subalpine valleys. {Macoun.) 



Vai-. 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.) 



315. ARNICA.

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

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