This thermophilous oak forest of sunny slopes on base-rich soils is a transitional type between the dry and open thermophilous oak forests, represented by the two previous associations, and mesic oak-hornbeam forests. It is dominated by Quercus petraea agg. or Q. pubescens agg., which are accompanied by mesophilous tree species. The shrub and herb layers are composed of a mixture of oak-forest and forest-fringe species with mesophilous forest species. In the driest areas, Euphorbio-Quercetum usually occurs as a transitional zone between Quercus pubescens agg. forests on south-facing slopes and oak-hornbeam forests on north-facing slopes or valley bottoms. Towards the margins of the dry regions, however, it is often confined to the regionally most xeric habitats, specifically the upper parts of south-facing slopes. It occurs in northern and central Bohemia and southern Moravia.
