Three little known Festuco-Brometea communities are described from the valleys of the rivers Krems, Kamp, Thaya/Dyje, Rokytná, Jihlava, Oslava and Svitava (south-eastern edge of the Bohemian Massif, Austria and Czech Republic). These communities are confined partly to natural forest gaps on the south-facing upper portions of cliffs, but also to secondary habitats. The Inulo oculi-christi-Stipetum pulcherrimae Vicherek et Chytrý in Chytrý et Vicherek 1996 (Festucion valesiacae) is a dry grassland on basic soils, particularly on marble and Permo-Carboniferous conglomerate in warmer parts of the study area. The Genisto tinctoriae-Stipetum joannis ass. nova (Festucion valesiacae) is a dry grassland vicariating with the Inulo oculi-christi-Stipetum pulcherrimae in cooler and wetter areas. Its localities are concentrated on amphibolite, marble and limestone. The Centaureo stoebes-Allietum montani ass. nova (Alysso-Festucion pallentis) is an open dry grassland on rock ledges affected by soil erosion, confined to different (particularly basic) bedrock types.
