Resumo

Two rare species of indigenous flora were for the first time recorded on the territory of the Republic of Tyva: Astragalus consanguineus Bong. et C.A. Mey., and Allium udinicum Antsup. Astragalus consanguineus was previously known on the territory of Russia only in the steppe zone of the West Siberian Plain from the border areas of the Omsk Region adjacent to Kazakhstan. Allium udinicum was considered endemic to the flora of Buryatia. Exact geographical coordinates of the new localities of these species, their main morphological differences from similar species, accompanied by photographs, are given in the paper.
