The article presents the results of a detailed comparative floristic analysis of the floras of wetlands of the main river basins of Armenia. The taxonomic structure of the floras of individual basins and the ratio of life forms are considered, as well as a detailed chorological analysis is carried out. It is shown that, in general, the flora of the wetlands of Armenian river basins is mainly Holarctic, Circumboreal. The base of it constitute species are widely distributed in the north of Eurasia in the Postglacial period. A very large influence on the development of this flora had Ancient Mediterranean species survived the Ice Age in the more southern regions, in the Ancient Mediterranean. These species by their bio-ecological characteristics belong to hydro- and hygrophilous groups which are growing in wetlands in arid regions of the Earth. As for the features of the floras of separate river basins, they reflect the correct distribution of the territory of Armenia between Caucasian and Armeno-Iranian floristic province (between Circumboreal and Ancient Mediterranean subkingdoms of Holarctic floristic kingdom.
