Occurrences of Oxytropis species on the territory of Asian Russia

The dataset providing information on the geographic distribution of Oxytropis species on the territory of Asian Russia is discussed. Different sources (prominent floras and compendia, modern papers, Red Data books, and field data) have been used to describe diversity and distribution of the one of the richest genera in Northern and Central Asia. Presented species distribution data cover purely studied regions of Russia and reveal different geographic patterns on species and supraspecific levels of organization. Presented dataset will be helpful in understanding ecological features and main determinants limiting distribution of Oxytropis species.
