Type: article
Abstract: Chromosome numbers (2n) are given for 12 species from the families Asteraceae and Fabaceae from Southern Siberia and Mongolia, including 10 diploids and 2 octoploids, with base numbers ranging from 8 to 14. For 3 species, the chromosome number was studied for the first time: Astragalus arkalycensis (2n = 64) for the Republic of Altai, Astragalus consanguineus (2n = 16) for the Republic of Tuva and Caragana buriatica (2n = 16) for Mongolia. For the first time in the Altai Territory, the chromosome numbers for Astragalus follicularis (2n = 16) and Oxytropis setosa (2n = 16) were determined. For the first time for the Republic of Tuva – Oxytropis martjanovii (2n = 64), Oxytropis saposhnikovii (2n = 16). For the first time for the Republic of Altai – Saussurea daurica (2n = 28). For all studied species, photographs of metaphase plates and plants in natural conditions in the places where the studied material was collected are provided, brief information on the general distribution and literary data on chromosome numbers are given.
