This vegetation type is dominated by Batrachium rionii, an aquatic macrophyte with submerged leaves, which forms open stands with less biomass than typically produced by other Batrachium species. It occurs in shallow, warm fishpond margins and pools at depths of 20–60 cm. Water is naturally eutrophic, with elevated salt concentrations. It is a rare vegetation type confined to warm areas, recorded in central Bohemia and southernmost Moravia.
