Tragopogon turcicus Coşkunç., M.Gultepe & Makbul, a new diploid species (2n = 2x = 12), is described and illustrated from Kızıldağ National Park (Isparta), southwest Anatolia. It is morphologically similar to T. oligolepis Hartvig & Strid which is also endemic to Turkey. Diagnostic characters, description, conservation status together with micro- and macro-morphological properties of achenes and pollen grains are given. A phylogenetic analysis based on nrDNA ITS sequence data indicated that T. oligolepis is the sister species of the new taxon.
