The Khorumnug-Taiga Range is situated on the South-East of the Tyva Republic. It is a link in the mountain chain separating the arid landscapes of Southern Tuva and Mongolia and the boreal landscapes of Southern Siberia. Such position of the range determines the contrast ecological conditions, a variety of plant communities and habitats, as well as a diversity of vascular plant species on its territory. The study of the flora of the range is of interest in the framework of the inventory and conservation of plants in the Tyva Pepublic. The flora of the Khorumnug-Taiga Range comprises 655 species of vascular plants belonging to 260 genera and 64 families. The 10 biggest families of the flora are Asteraceae (78 species), Poaceae (73), Rosaceae (42), Ranunculaceae (41), Cyperaceae (40), Caryophyllaceae (38), Fabaceae (33), Brassicaceae (24), Salicaceae (24), Lamiaceae (17). The eight largest families are the same as the eight largest families of the floras of the other mountain structures in the South Tuva: massif Mongun-Taiga, ranges Tsagan-Shibetu, Western and Eastern Tannu-Ola. By the first three largest families (Poaceae, Asteraceae, Rosaceae), the flora of the Khorumnug-Taiga Range, as well as the flora of nearly situated Eastern Tannu-Ola Range, belongs to Central-European Rosaceae-type. Nine species of the flora included into the Red Data Book of the Tyva Republic, two species - into the Red Data Book of the Russian Federation: Cypripedium calceolus L. and C. × ventricosum Sw.
