Holosteum marginatum Fisch. & C. A. Mey. in Bull. Soc. Imp. Naturalistes Moscou 11: 402. 1838. Holosteum marginatum was reported for Turkey and the Caucasus by Coode (1967: 860), for the Caucasus and Iran by Murav'eva (1936: 361), and recently, it has been regarded as an Irano- Turanian floristic element by Heller & Heyn (1994: 67). The species was neither reported from Crimea by Greuter & al. (1984: 214) nor by Jalas & Suominen (1983: 85) and Produkin & al. (1987). Its first report from Crimea was published by Golubev (1995: 49), who found it on Chatyrdah, but the voucher supporting this record has not been located. The occurrence of the species was later confirmed by Fedoronchuk & Didukh (2002: 113). We add here a second record of the species from Karadag (Fig. 1). Our specimens have small glandular hairs on the always erect pedicels; the flowers open one by one, the petals have a ciliate claw and are 1-1.5 times longer than the sepals. CRIMEA: Karadag Zapovidnyk, between Kurortne and Koktebel, 200-450 m, foothills, dry grasslands and cliffs, 5.6.2001, Boratynski, Didukh, Romaschenko, Romo 10307 & Susanna (BC).
