Cespitose, with the caudex covered with the brown scarious stipules and old leaves. 

 Stems several, 1-2 dm. high, more or less tomentose or villous, few-leaved. Basal 

 leaves on petioles 2-5 cm. long, ternate, glabrate or slightly villous above, densely white- 

 tomentose beneath ; leaflets oblong-cuneate or obovate, 2-3 cm. long, generally coarsely 

 crenate. Stem leaves similar but smaller. Cyme 2-6-flowered. Flowers 12-15 mm. in 

 diameter. Hypanthium 6-8 mm. in fruit, white-villous or tomentose ; bractlets linear, 

 oblong or lanceolate, slightly shorter than the ovate lanceolate acute sepals. Petals 

 obcordate, a little exceeding the sepals. 



The common form of this species is fully as tall as P. villosa and P. Hookeriana, but 

 very slender. The flowers are only 15 mm. in diameter, the bractlets linear-oblong or lan- 

 ceolate, shorter than the ovate-lanceolate sepals. The obcordate petals only a little exceed 

 the sepals. The leaflets are 2-3 cm. long, oblong or obovate, with broad teeth. P. nivea 

 is distributed throughout the arctic regions and in the higher mountains of the northern 

 hemisphere. In America it ranges from Labrador to Alaska, extending in the Rockies 



1 Including P. unifiora and P. Waliliana.
