The synopsis includes 62 species, 51 of them are endemic to Mountain Middle Asian floristic province, including 16 endemics of Western Tian Shan and 17 endemics of Pamir-Alay; eight species are national endemics, six are listed in the Red Data Book of Uzbekistan. Three species (O. baldshuanica, O. ovczinnikovii and O. trajectorum) are reported as new for Uzbekistan, O. submutica is a novelty for the flora of Kyrgyzstan. Distribution maps, species richness and collection density map based on all known records are provided; distribution patterns of Oxytropis species in Uzbekistan within phytochoria, mountain ranges and vertical zones are analyzed. Hissar Range in Pamir-Alay and Chatkal Range in Western Tian Shan are identified as “hot spots” of Oxytropis diversity in Uzbekistan.
