(b) Subsp. carniolicus (Willd.) Br.-Bl. , Neue Denkschr. Schweiz. Naturf. Ges. 48: 300 (1913):

Lamina of basal leaves oblanceolate or narrowly obovate in outline. Achenes glabrous. 2zi = c. 120, c. 160. C. & E. Alps; Carpathians.

Typical plants of subsp. (a) have more or less deeply pinnatifid leaves which are usually densely sericeous-lanate, whilst those of subsp. (b) have shallowly lobed or crenate leaves much less densely hairy and sometimes subglabrous. There is much variation in hairiness, however, and many intermediates occur; one of these, in the E. Alps, has been called subsp. insubricus (Chenevard) Br. -Bl., loc. cit. (1913).
