(Boraginaceae-Lithospermeae) includes about 150 species distributed in Asia and Europe (ElShazly et al. 2003). The genus has been divided into 3 sections: Onosma, Protonosma, and Podonosma (Riedl, 1978). Section Onosma was separated into 2 subsections according to indumentum type: Asterotricha (Boiss.) Gürke and Haplotricha (Boiss.) Gürke (Riedl, 1978). Based on the current knowledge, in Turkey there are 97 species, 4 varieties, 1 hybrid species, 50 endemic species, and 1 endemic variety in the genus Onosma and the degree of endemism for the genus in Turkey is 50% (Yıldırımlı, 2000; Riedl et al., 2004; Akçin, 2007; Binzet & Orcan, 2009). In this paper, the new species Onosma beyazoglui Kandemir & Z. Türkmen from eastern Anatolia is described. It has setae on leaves arising from glabrous tubercles and belongs to sect. Onosma subsect.
