This marsh type is dominated by Carex pseudocyperus and, less frequently, by the umbellifer Cicuta virosa. It occurs in mesotrophic to dystrophic, in some cases secondarily eutrophic habitats in an advanced stage of terrestrialization, e.g. fishpond littoral zones with accumulated organic sediment, oxbows, alluvial pools and pools in canopy openings of alder carrs. Water depth is usually less than 30 cm, but the water table can recede during the summer to expose the bottom; even when this happens, however, the substrate does not dry out. The association occurs from lowland to submontane areas of the Czech Republic, being more common in precipitation-rich areas.
