Anahtar sözcükler: Apocynaceae, Vinca, Kemaliye, Erzincan, Türkiye florası Introduction The genus Vinca L. (Apocynaceae) is native to Europe, north-west Africa, and south-west Asia and comprises 6 species: Vinca difformis Pouret, V. erecta Regel & Schmalh, V. pubescens d’Urv., V. herbacea Waldst. & Kit., V. major L., and V. minor L.; the last 3 occur in Turkey (Stearn, 1972, 1973, 1978). However, during a botanical excursion to Sarıkonaklar village in Kemaliye District in 1992 Dr. Pharm. Osman SONER and I found a species yet unknown, forming a large population on stony dry slopes. It is an erect subshrub with dark green leaves and blue-whitish flowers, which differs from the 3 species of Vinca recorded in Turkey (Stearn, 1978). We took coloured pictures of the plant and collected herbarium specimens. Voucher specimens are stored in Ankara University Faculty of Pharmacy Herbarium (AEF). As a result, I described this new species of Vinca and provided a key to distinguish it from the other Vinca species from Turkey. In Turkey it is always .
