Abstract: 

The genus of Onosma (Boraginaceae) contain almost 150 species in worldwide and distributed in Mediterranean and Iran- Tourane region and 37 species of that distributed in Iran. The main purpose of this study was to analyze palynological characters of the members of the genus and evaluating the efficiency of these features in systematics of it. Palynology scanning electron microscopy studies of eight species of the genus of Onosma such as: O.araraticum Riedl, O.bulbotrichum DC., O.cardiostegium Bornm, O. dichroanthum Boiss., O.elwendicum Wettst., Bgc. O.longilobum, O.microcarpum Steven O.sericeum Willd. ex DC. indicated that structure and shape of pollens are important characters for identification among species. All of the species pollen had opposite pole, oval shape and almost triplate and tricolporate and surface of pollen was granulated.
