In this study, plant morphology and palynology of 40 populations belonging to 17 species from 3 sections of the genus Onobrychis, namely Afghanichae, Heliobrychis and Lophobrychis, were investigated. In morphological study, 59 quantitative and qualitative characters comprising vegetative and reproductive structures were investigated and 3 groups were distinguished. In spite of the comparatively homogenous morphological features including, 3-colpate and reticulate ornamentation, a considerable variation was observed in the quantitative morphological characters of the pollen grains. However, among the studied pollen morphological characters, equatorial and polar diameters were more significant than others and based on these data, the members of the studied sections could be divided into 3 groups. This confirmed the results obtained from morphological survey.
