Diversity of aquatic vegetation (Lemnetea O. de Bolòs et Masclans, Potamogetonetea Klika in Klika et Novák 1941) in the Russian Federation

Abstract

In a frame of the project “Vegetation classification of Russia”, we have compiled the prodromus of two classes of aquatic vegetation, i.e. Lemnetea O. de Bolòs et Masclans 1955 and Potamogetonetea Klika in Klika et Novák. The diversity of Lemnetea in the Russian Federation is consists of 15 associations belonging to 3 alliances and one order. Diversity of Potamogetonetea is presented by 56 associations from 5 alliances and two orders. The presented version of the prodromus is a preliminary. We count all valid sytaxa revealed from the territory of the Russian Fedeeeration. The final prodromus will be obtained after the numerical data processing and considering the plurality of syntaxonomic decisions.
