This association includes meadows on intermittently wet and nutrient-poor soils which are more acidic than in the previous association. It is distributed in higher colline and submontane altitudinal belts, but it appears to be absent from the lowlands. The stands are usually dominated by Molinia arundinacea or M. caerulea, which are accompanied by species of intermittently wet soils as well as those typical of wet oligotrophic habitats. This meadow type is most common in southern and central Bohemia and in the Českomoravská vrchovina Uplands.
