This association includes open stands of Festuca pallens, Aurinia saxatilis subsp. arduini and some other thermophilous perennial herbs, growing in crevices of steep cliffs and on small ledges on siliceous rocks. It is common on the volcanic hills of the České středohoří in northern Bohemia and in deep river valleys of central Bohemia and south-western Moravia. Some isolated and usually species-poor stands are also found in river valleys in other areas of the Bohemian Massif.
