This association includes flooded meadows along large rivers in dry lowlands. These meadows are found in slightly higher places within the floodplain microtopography than those of the association Lathyro palustris-Gratioletum officinalis. Spring floods accordingly last only for a few days and summer drought is more pronounced. The stands of this association contain several species showing continental distribution. In the Czech Republic this vegetation is restricted to the floodplains of the Dyje and Morava rivers in southern Moravia.
