Introduction Centaurea L. is the fourth largest genus of the family Asteraceae, comprising between 400 and 700 species with predominantly old world distribution ranges (Dittrich, 1977; Bremer, 1994; Wagenitz and Hellwig, 1996; Bancheva et al., 2014). It is distributed in the Mediterranean region and the Near East with a few species reaching northern Eurasia, north and east Africa, North America, and Australia (Wagenitz, 1986). The genus Centaurea L. has traditionally been considered a problematic genus in Astraceae (Ranjbar et al., 2013). Turkey is the most important center of speciation of Centaurea, with many narrow endemic species. The first thorough arrangement of the genus Centaurea was given by Wagenitz (1975), who recognized 172 species and six imperfectly known species. In the Flora of Turkey and the East Aegean Islands 34 sections of Centaurea were presented (Wagenitz, 1975). Recently Centaurea was revised for Türkiye Bitkileri Listesi by Uysal (2012a). The number of known Centaurea species in Turkey is 162 [(excluding 56 species .
