Substrate: siliceous rocks, calciferous rocks, intermediate rocks (such as calciferous schists)

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the nival belt (above the lower limit of perennial snow and glaciers)
