(b) Subsp. discolor (Koch) Arcangeli View in CoL , Comp. FI. Ital. 626 (1882):
Leaves glaucous or whitish beneath; petiole the length of the leaf. Common in the S. & E. o f the area o f the species and in the valleys o f the Alps. The native distribution of the two subspecies is difficult to define precisely because they are frequently cultivated. Var. villarsiana (Flügge) Rouy is characterized by short, shiny branches and small, ovate or elliptical leaves rounded at the base, white beneath (France, Switzerland). It seems to be common in some valleys of the W. Alps and, though related to subsp. discolor , might represent another geographical subspecies.
