✦ Synopsis

Aquatic macrophytes with oceanic and suboceanic distribution occur in the G.D.R. mainly in Littorelletea, Isoeto-Nanojuncetea and Montio-Cardaminetea communities. Within the Potametea they are almost entirely confined to the Ranunculetumfluitantis and to the group of Batrachium communities within the Nymphaeion. Within the territory of the G.D.R. several of these species are reaching the eastern border of their distribution areas. Nearly all of them are more or less endangered or even threatened by extinction.
