(b) Subsp. pyrenaicum (Lam.) Bonnier & Layens , loc. cit. (1894)

( H. pyrenaicum Lam. , H. pollinianum Bertol. , H. sphondylium subsp. montanum auct. pro parte, non (Schleicher ex Gaudin) Briq.):

Stem pubescent or setose below. Leaves simple, with 5-7 usually acute or acuminate primary lobes, softly pubescent, hispid or densely white-tomentose beneath. Rays 12-45. Petals white, outer radiate. Commissural vittae conspicuous. • Pyrenees, Alps, N. Appennini , mountains of the Balkan peninsula.

Plants with the leaves densely white-tomentose beneath may be referred to var. pyrenaicum , while those with leaves pubescent or setose beneath may be referred to var. pollinianum (Bertol.) Thell. Both varieties probably occur throughout the range of the subspecies.
