Based on the analysis of the author's surveys of the studied areas, a conclusion is made about the floristic composition of vegetation on the right Bank of the Yessil river. The list of species was identified, the generic and species composition of the studied plants growing in the floodplain of the river was studied. Based on our research, 122 species from 102 genera (35.6 %) and 44 families were identified. Among angiosperms (Magnoliophyta), with 119 species (97.5 %), Dicotyledoneae predominate - 99 species (81.01%) from 81 genera (85.3%) and 32 families (72.7%). The class Liliopsida includes 20 plant species (16.4%) from 9 families (20.5%) and 18 genera. The largest family of the studied local flora includes 7, among them: Asteraceae, Rosaceae, Poaceae, Fabaceae, Salicaceae and Lamiaceae.
