Taraxacum kok-saghyz L.E.Rodin is a promising natural rubber source and an alternative to Hevea brasiliensis (Willd. ex A. Juss.) Müll.Arg. At the same time, T. kok-saghyz is a narrow endemic and a rare species with decreasing population size due to degradation of its natural habitat. Therefore, it is listed in the Red Data Book of Kazakhstan. Despite a large number of studies addressed various characteristics of this plant, the data on the floristic composition of plant communities it is part of are limited. The aim of our studies was to assess the floristic composition of plant communities with the participation of T. kok-saghyz. The article presents the most complete, up-to-date list of the flora comprising 169 species belonging to 110 genera and 35 families. We present the results of an analysis including taxonomic, chorological and ecological data, identified the basic spectrum consisting of 29 species which are the most characteristic indicators of the plant communities studied. For the first time, the core of the flora was determined, consisting of 14 species. According to the habitat type, most of the basic spectrum was formed by mountain species (14) including one narrow endemic (Ketmentau), followed by Palaearctic species (8). According to ecological preferences, the following groups were distinguished: mesophytes (9 species), mesoxerophytes (7 species), and halophytes of various types (9 species). The share of species preferring saline habitats (halophytes) was 31.4 %. The most similar (Kochs index of biotal dispersity of 23.1 %) were communities at the western border of the surveyed area, and the value of the index gradually decreased towards the eastern border (from 22.7 % to 18.7 %). The results obtained can be important in the further studies on the populations of T. kok-saghyz, in searching for potential habitats and organizing population monitoring.
