with the radical leaves, form a thick turf. They 

 probably assist in protecting it from the rigour of 

 winter. The upper or herbaceous part, is hairy 

 and tomentose, becoming silky beneath the 

 calyx. 



Leaves ternate, silky, particularly the upper sur-

 leaflets ob-ovate, the two outer trifid, the cen-

 covered with fine silky hairs. Stem-leaf (for

Stipules broad, embracing the stem. 



Calyx hairy and tomentose ; the segments unequal. 



Flowers terminal, solitary, large, rarely two on the 

 same stem. 



Petals emarginate, inversely kidney-shaped, of a

Anthers on very short filaments, and few in num-

Seeds. I have not seen. 



Duration perennial. Hah. West Coast of Green- 

 land. Altitude 300 feet. Time of flowering, 

 June and July.
