Abstract

The article presents the results of the study of the Tsagan-Khag cluster area flora of the Rostov State Nature Reserve in the southeast of the Rostov region. The flora of this area is represented by 233 species of covered plants from 151 genera of 38 families. As a result of this work, 57 species were identified, which are first listed for the Tsagan-Khag site. Eight species were identified for the first time for the entire territory of the Rostov State Nature Reserve and its protected zone: Allium regelianum A. K. Becker, Centaurium pulchellum (Swartz) Druce, Cerastium perfoliatum L., Eleocharis uniglumis (Link) Schult, Euphorbia falcata L., Heliotropium europeum L., Serratula cardunculus (Pall.) Schischk., Veronica barrelieri H. Schott ex Roem. et Schult. The rare flora complex of the Tsagan-Hag site is represented by 10 species of angiosperms: Allium regelianum, Althenia orientalis (Tzvelev) García-Mur. et Talavera, Bellevalia speciosa Woronow ex Grossh., Frankenia pulverulenta L., Iris pumila L., Stipa sareptana A. Beck., S. ucrainica P. Smirn., Tamarix gracilis Willd., Tulipa biflora Pall., T. suaveolens Roth, 3 species of which have federal conservation status (Allium regelianum, Bellevalia speciosa, Tulipa suaveolens).
