Reassessment of diversity and analysis of distribution in Tulipa (Liliaceae) in Uzbekistan

The diversity and distribution of the genus Tulipa in Uzbekistan are discussed; 34 taxa of Tulipa are recognized in Uzbekistan. The taxa were mapped using GIS software and their distributions were analyzed. Six species are endemic to the country. A national check‐list of Tulipa was created based on the classification developed by Zonneveld (2009). ‘Hot spot’ areas of tulip diversity in Uzbekistan are western Tien‐Shan (18 taxa), the western Pamir–Alay mountains (18 taxa) and the Turan lowland (5 taxa). An assessment of rare tulip species according to IUCN red list categories and criteria was performed for the first time for Uzbekistan. Evaluation of the latest classification of Tulipa clearly shows that further studies are required to arrive at a natural classification of the genus.
