This area habitat is located at the overlap of different floristic regions; on its northeast side, Central Asian desert flora is dominating, and on the eastern side, East Asian flora is observed. The comprehensive survey was carried out to find the floral diversity of the medicinal plants on the region. Methods: All recorded species in this study were based on the collected voucher specimens between June and August in the year 2017. Results: We recorded 23 families, 57 genera, and 78 species of vascular plants. The families Asteraceae (15 species), Fabaceae (10 species), and Amaranthaceae (10 species) were represented most in the study area, while Caragana (5 species), Salsola (4 species), and Arnebia (3 species) were the most common genera found. Conclusion: Conservation status for remarkable species was also reviewed based on the literature. Around the study area, 24 species as “sub-endemic,” 10 species as “very rare,” 4speciesas“rare,” 1speciesas“alien,” 13 species as “relict,” 10 species as “Red Book,” 2speciesas“endangered (EN),” 3speciesas“vulnerable (VU),” 3speciesas“near threatened (NT),” and 2 species as “least concern (LC)” plants are growing.
