This vegetation type is dominated by Batrachium aquatile or B. peltatum, aquatic macrophytes with both submerged and natant leaves. Depending on the habitat, one of these two leaf types can be reduced or absent. The association occurs in shallow, seasonal or permanent, mesotrophic to eutrophic water bodies such as fishponds, flooded sand or loam pits, fish storage ponds, oxbows and channels. It also occurs in middle to lower river courses with medium to low current velocity. Habitats are usually well insolated and water is up to 1 m deep. In the Czech Republic this association occurs mainly in colline to submontane areas.
