This association includes grasslands dominated by Festuca versicolor, which contain several basiphilous alpine species. It occurs on outcrops of base-rich rocks in the Krkonoše Mountains, namely in two glacial cirques on the Czech side (Velká Kotelní jáma, Obří důl) and one cirque on the Polish side of the mountain range (Malá Sněžná jáma).
