A well-marked, hardy, Himalayan species of Potentilla, with 
a compact habit and large yellow flowers, produced abundantly 
during the summer months. Jacquemont detected it in fissures 
of rocks in Kanaor, near Rogui, elev. 9,000 feet, in about lat. 
32°, long. E. 783°, where it was likewise found by Capt. Henry 
Strachey ; thence it appears to extend eastward through Nepal to 
Sikkim-Himalaya, where it was found by Dr. Hooker in woods 
at an elevation of from 12—13,000 feet above the level of the sea. 
Its nearest affinity is with P. eriocarpa, Wall.; but there the stem 
is scarcely leafy, and the leaflets are longer and much more ~ 
divided. 
Descr. From a woody perennial roof, many closely-placed 
stems diverge: they are ascending, six inches to a foot long, fre- 
quently purple, leafy, clothed with soft silky hairs, as 1s, more 
or less, every part of the plant. Leaves on longish petioles 
(which have two large, ovate, usually entire stipules at the base), 
ternate ; Jeaflets cuneato-obovate, trifid at the apex, of a firmish 
texture, glaucous beneath, the lateral ones sessile, the terminal 
one on a short petiolule. Peduncles slender, terminal, single-
