This paper reviews the classification scheme of riparian vegetation (the class Phragmito- Magnocaricetea) of the northern Left-Bank Forest-Steppe. The physical geography peculiari ties of the region are described. The northern part of the study area shares a border with Polissya. The eastern part borders on the western spurs of the Central Russian Upland. In the western part the flat relief of the study area contains marshes. Meadows are mainly in the floodplains of the Uday, Oster, Romen, Sula, Seim rivers. In the study area the following associations are identified: Caricetum vesicariae Br.-Bl. et Denis 1926, Glycerietum fluitan tis Wilzek 1935, Carici acutae-Glycerietum maximae (Jilek et Valisek 1964) Shelyag, V. Sl. et Sipaylova 1985, Poetum palustris Resmerita et Ratiu 1974, Beckmannietum eruciformis R. Jovanovic 1958. These associations depend on the alliances Caricion gracilis Neuhäusl 1959 em. Balátová-Tuláčkova 1963, Sparganio-Glycerion fluitantis Br.-Bl. et Siss. in Boer 1942, Poion palustris Shelyag, V.Sl. et Sipaylova 1985 and on the orders Magnocaricetalia Pignatti 1953, Nasturtio-Glycerietalia Pignatti 1953 em. Kopecký 1961 in Kopecký et Hejný 1965, Galio palustre- Poetalia palustris V.Sl. 1996. The floristic diversity of the class comprises 66 genera, 26 families, 104 species (100 %). Equisetophyta includes two species (1,92 %), Magnoliopsida – 60 species (57,69 %), Liliopsida – 42 species (40,39 %). The class contains 22 syntaxa: three orders, three alliances, five associations, two subassociations, nine variants. The diversity of taxa and syntaxa of the class Phragmito-Magnocaricetea depends on the wide diversity of habitats.
