Substrate: calciferous rocks, calciferous soil

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: optimum in fissures of base-rich or lime-containing metamorphic rocks, most frequent in dry valleys of the Alps, but rarely reaching beyond treeline.
