This association is similar to the previous one, but occurs on drier slopes, where the growth of oaks is stunted and the canopy very open. It is dominated by Quercus petraea agg. The shrub layer is sparse, mostly consisting of low-growing individuals of the dominant species. The herb layer is characterized by the constant occurrence of the dwarf shrub Genista pilosa and the graminoids Carex humilis and Festuca ovina, accompanied by drought-adapted acidophilous species. A moss layer is well developed with Ceratodon purpureus, Polytrichum piliferum and several species of lichen genera Cladonia and Xanthoparmelia. It occurs on south-facing outcrops of poorly weathering acidic rocks such as granite, gneiss and granulite in the river valleys of south-western Moravia.
