This association is dominated by Potamogeton acutifolius, a submerged narrow-leaved species, which is in places accompanied by other narrow-leaved Potamogeton species or other aquatic macrophytes. It occurs in mesotrophic to eutrophic, often calcium-rich, clear water at depths up to 1 m, including less intensively managed fishponds, channels, flooded sand pits and sylvan pools. In the Czech Republic it is a rare association, which has been recorded at a few sites in lowland and colline landscapes.
