Upper half of involucral bracts in female plants lanceolate, dark greenishbrown, erose above. 2л = 70, 84, 85. Mountain rocks and heaths', calcicele. • N. & W. Fennoscandia, just extending to N. W.

Apomictic. Male plants are known only from scattered localities in Norway and W. Sweden; they do not produce functional pollen.

The closely related A. boecherana A. E. Porsild , Bot. Tidsskr. 61: 36 (1965), from Iceland (and from Greenland and N. Canada), differs in having leaves which are nearly always densely tomentose on the upper surface and in having 2л = 56; only female plants are known.
