География караганы гривастой (caragana jubata (pall.) poir.) и ее фитоценотическая роль в растительном покрове гор

The spatial distribution of Caragana jubata (Pall.) Poir. is analyzed on the basis of herbarium materials, literary data and online documents. The analysis of spatial distribution of Caragana jubata made it possible to reveal the heterogenic distribution of occurrence sites of the species, resulting from the history of species origin and resettlement, as well as its coenotic association. Caragana jubata has a disjunctive area. Moving northward from the center of origin in the Himalayas and the Tibetan Plateau through the mountain systems, the species found favorable habitats in the mountains of the Eastern Sayan and the Stanovoye Highlands,  where it is a relict of the Tertiary period. Basing on the map of the spatial distribution, the geographical aspects of Caragana jubata participation in vegetation cover of the different regions were revealed.
