This alliance encompasses dry grasslands of limestone and dolomite outcrops in the Pannonian floristic region. These grasslands are often dominated by Festuca pallens and contain a number of species of submediterranean distribution and some endemics of the limestone fringes of the Eastern Alps and the Western Carpathians. This alliance is found in colline landscapes at the edge of the Carpathian Basin. It is vicarious to the alliance Xero-Bromion of south-western Central Europe.
