In east-west direction it spreads from Dolomites to Julian Alps. It doesn't protrude much to the north. Already in our northern neighbor Austria it is considered a rare plant (Ref.: (1)). Contrary, it can be abundantly found more south in Apennines and Balkan Peninsula. This plant, which thrives in Slovenia only at high elevations from 1.600 to 2.000 m (Ref.: (4)), is beautiful in its appearance since its flower heads can measure up to 4 cm in diameter. It can be recognized by milky-white, stalk-less flowers and calyx with ten nerves and five more or less equally long teeth (see Fig. 10). Uppermost small and narrow leaves just below the flower heads are few and are allover softly hairy.Ref.:(1) M.A. Fischer, W. Adler, K.
