A list of vascular plant species present in the Tuvinian depression but absent in depressions of South Tuva and West Mongolia has been compiled. It is shown that Tannu-Ola mountain range is a boundary for southenly distribution of some steppe species. The range also forms a barrier for moisture carrying air masses. As a result the flora of the Tuvinian depression is enriched by forest and meadow species.
