A new project, 'Flora of Uzbekistan', is announced to start with publication in 2017. It aims at publishing a multi-volume taxonomic treatment of vascular plants of Uzbekistan, with complete synonymy, nomenclature, distribution data, descriptions and identification keys. The taxonomic treatment is supported by an extensive database of distribution records, used to generate distribution maps. The background information for the Flora is provided, and the structure and the format of the work are outlined.

A check-list of endemic vascular plants of the Tian-Shan Mountains, including plant distribution along mountain ranges and in Central Asian countries, has been compiled for the first time in this study. The list of Tian-Shan flora consists of 871 endemic species and subspecies. One subspecies belongs to Pinaceae (Pinopsida) and 870 taxa belong to Magnoliidae (dicots, 732 taxa, and monocots, 138 taxa). The endemic flora belongs to 39 families and 187 genera. The largest number of endemics is concentrated in the mountain ranges of Kyrgyzstan (225 national endemics, 507 taxa in total) and Kazakhstan (205 national endemics, 485 taxa in total). Uzbekistan occupies the third position (69 national endemics, 320 taxa in total). Tajikistan has fewer endemics: 82 taxa, of which only 16 taxa are national endemics. The most represented families and genera are: Asteraceae, Fabaceae, Apiaceae, Lamiaceae, and Amaryllidaceae; and Astragalus, Allium, Cousinia, Oxytropis, and Gagea, respectively.

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.

The article is devoted to the 80th anniversary of the Institute of Botany of the Academy of Sciences of the Republic of Uzbekistan and the 130th anniversary of one of its founders and leaders, prominent botanist and academician Yevgeniy Petrovich Korovin. A brief essay of the history of the Institute of Botany and a list of the most important publications for 80 years (1940–2020) are given.
