This association is dominated by Utricularia vulgaris, a submerged, freely floating bladderwort. It occupies shallow mesotrophic to naturally eutrophic, calcium-rich alluvial pools or pools within fen complexes, which are in an advanced stage of terrestrialization and contain a deep layer of organic sediment at their bottom. In the Czech Republic this association occurs rarely in the middle Labe area.
