| Potentilla chamissonis Hult. |
Potentilla chamissonis is distributed across Svalbard, northern Norway, Greenland and the eastern Arctic of Canada.
It is a loosely tufted plant growing from a stout stem base, reaching to 10-25 cm tall. The basal leaves are 3- (rarely 5-) foliate, hairy above, and densely tomentose beneath, the petioles and stems with long, straight hairs. The inflorescence is branched, bearing several fairly large flowers. The flowers have five petals, pale yellow, inversely heart-shaped, longer than sepals.
It grows on ledges on steep slopes, and in crevices.
