Rather rare, on clayey and sandy flats on the beach. 
Kingorsuak in several places, Ikerasausak, Tunok, Kordlortok 
and Grünlænderpynt at Tasiusak. 
Is as a rule very low, compressed with 3—4 ctm. long leaves, 
with 2—3 couples of leaflets and abt. 20ctm. long, 4—5 jointed 
offshoots, but in favourable localities vigorous specimens appear with 
12 ctm. long leaves (5 couples of leaflets) and 50—60 ctm. long 
offshoots with 10—12 ctm. long joints. Flowers abundantly and 
sets many fruits. In spring the leaves are strongly reddish brown, 
later in the year they commonly assume a somewhat greenish colour. 
Flowers from the middle af July to the middle of August, with 
fruit in August.

1) There seems to me to be no reason of separating with Rydberg 
(Further studies on the Potentilla) this variety as a distinct species (P. 
Langeana Rydb.), as the characters referred to are very variable, and 
numerous transitions are found. In the same plant the outer calyx 
and the leaf denticles may be obtuse and acute, the sepals oval or oval- 
lanceolate, and even the hairiness of the upper surfaces of the leaves 
and the under calyx are very variable. Completely glabrous leaves are 
rare. Neither do these characters vary in a parallel way; in almost 
glabrous specimens (shade-loving forms) the stem is upright with up- 
right branches, the leaf denticles obtuse, while outer a and calyx 
are lanceolate and more or less acute.
