This association includes stands of Potamogeton .angustifolius, a stable hybrid of P. gramineus and P. lucens, which possesses large submerged leaves, and often also natant leaves. The parent species and some other aquatic macropytes may also occur in these stands. The association has been recorded only at two sites in eastern Bohemia, both in small fishponds with mesotrophic to naturally eutrophic water, at depths of 10–60 cm.
