A new halophytic species, Scorzonera tuzgoluensis A. Duran, B. Doan & S. Makbul sp. nov. (Asteraceae), is described and illustrated from Tuz Lake, central Anatolia, Turkey. The new species grows in salt marshes, is endemic (confined to central Anatolia) and closely related to Scorzonera parviflora Jacq. and S. elata Boiss. The diagnostic morphological characters of these similar taxa are discussed. The ecology, biogeography and conservation status of the new species are also presented. The geographic distribution of the new species and related species is mapped.
