The article provides brief geobotanical characteristics of plant communities of three populations of R. iliensis Chrshan. found in the floodplains of the Ili and Sharyn rivers, as well as presents the morpho-anatomical struc-ture of vegetative organs (stem and leaf) of the species under study. R. iliensis Chrshan. is undoubtedly a rare, endangered species of the flora of Kazakhstan. Its distribution area is shrinking from year to year as a result of the anthropogenic pressure on the environment. The biometric indicators of vegetative organs in the samples collected from populations 1 and 2 were approximately the same. The indicators of the samples collected from population 3 differed substantially. This is a completely natural process, since there are substantial differences in the climatic conditions of the upper and lower parts of the basin where the Ili River flows: a sharp increase in temperature and a decrease in precipitation from high to low hypsometric levels of the basin. Moreover, there is a gradual aridiza-tion of the territory from east to west. Naturally, this entails a change in both soil and vegetation cover as well as leaves its mark on the morpho-anatomical structure of vegetative organs. With this in mind, the authors recom-mend continuous monitoring of the state of the populations at the three sites where R. iliensis Chrshan. was found.
