Abstract :Pollen morphology of seven endemic Onosma L. taxa (Boraginaceae) from Turkey was investigated by using light (LM) and scanning electron microscopy (SEM). As a result of LM and SEM observations, it was found that the pollen types are generally syncolporate, anisopolar, and circular in polar view and the thickness of pertectate exine is 0.93-1.15 μm. Exine ornamentation was found as generally granulate-perforate, psilate, verrucate in polar area, mostly granulate and verrucate in equatorial area. While pollen shape is prolate-spheroid in O. circinnatum H. Riedl, subprolate in the rest of the examined taxa. The results also indicated that pollen characters are effective in separating the examined taxa.Keywords : Işık Mikroskobu, Onosma, Palinoloji, Taramalı Elektron Mikroskobu, Türkiye
