The paper is dealt with the study of vegetation of the «Romanivka mire» botanical nature sanctuary of the national importance. It has been found that its vegetation is represented by forest, aquatic, wetland, meadow, shrub, and ruderal phytocenoses. The syntaxonomic scheme, including 10 classes, 13 orders, 15 alliances, and 28 associations with their characteristics, is presented. The class Phragmito-Magnocaricetea occupies about 65-70 % of mire area and has the largest number of syntaxa and cenoflora species (15 associations and 81 species). The class Alnetea glutinosae covering about 15-20 % of mire territory is the second the most widespread syntaxon of plant communities. The habitats of plant communities within the territory of the mire are protected by the European Union Council Directive 92/43/EEC (N3150, N 3270, N 6430, andN 7140). The communities of the associations Lemnetum minoris, Lemno-Spirrodeletum, Lemnetum trisulcae, Calletum palustris, Lysimachio vulgaris-Filipenduletum, and Bidentetum cernuae are registered in these biotopes. Calla palustris, Veratrum lobelianum, and Menyanthes trifoliate are rare species for the city of Kyiv and the Kyiv region. Ostericum palustre is listed in the Appendix 1 of the Bern Convention.
