Abstract
Floras of mountain territories are of interest due to species richness and а large number of endemic and rare species. However plant checklists published in the second half of the last century turned out to be unsuitable for usage due to modern taxonomic treatments, reidentification of herbarium specimens and results of additional field investigations. The purpose of this work was to compile an actual checklist of the flora of the Eastern Tannu-Ola Range, in which takes into account literary data, the current taxonomic and nomenclature points of view, the results of field researches of the author and other botanists, as well as reidentification of specimens, stored in the herbaria of the Central Siberian Botanical Garden SB RAS (NS, NSK). The actual checklist comprises 1028 species and subspecies of vascular plants which belong to 373 genera and 86 families. Of these, 119 species are listed for the Eastern Tannu-Ola Range for the first time. The 10 biggest families are Poaceae (124 species and subspecies), Asteraceae (121), Rosaceae (66), Fabaceae (62), Ranunculaceae (59), Cyperaceae (55), Caryophyllaceae (43), Brassicaceae (41), Lamiaceae (33) and Scrophulariaceae (31). All the ten largest families are the same as the ten largest families of the Boreal Region and neighbouring Western Tannu-Ola Range and Tsagan-Shibetu Range. However the flora of the Eastern Tannu-Ola Range belongs to Rosaceae-type (Central-European) by the first three largest families (Poaceae, Asteraceae, Rosaceae), while floras of Western Tannu-Ola and Tsagan-Shibetu Ranges belong to Fabaceae-type (Mediterranian-Mongolian) by the first three largest families (Asteraceae, Poaceae, Fabaceae), this points out on the position of the ranges of the Southern Tuva on the world watershed and the proximity of their floras to both North Asian and Central Asian floras. Twenty six species of the flora included into the Red Data Book of the Russian Federation and/or the Red Data Book of the Tyva Republic.
