Is as a rule very low, compressed with 3 — 4 ctm. long leaves, 

 with 2 — 3 couples of leaflets and abt. 20 ctm. long, 4 — 5 jointed 

 offshoots, but in favourable localities vigorous specimens appear Avith 

 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.

^) There seems to me lo 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 ova! 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 calyx and calyx 

 are lanceolate and more or less acute.
