This closed herbaceous community is dominated by Trifolium medium and composed of species of mesic meadows and semi-dry grasslands. It is scattered across the higher colline landscapes and submontane areas, where it occurs mainly on gentle slopes and deeper soils. It is typical of forest edges, verges of forest roads and abandoned mesic meadows or semi-dry grasslands. The community occurs in habitats potentially supporting oak-hornbeam or beech forests throughout the country, but its distribution is not sufficiently known.
