In the present study, pollen and seed micromorphology of some Geranium L. species (G. asphodeloides, G. columbinum, G. dissectum, G. libanoticum, G. molle, G. purpureum, G. pyrenaicum, G. robertianum, and G. rotundifolium) distributed in Hatay was investigated using light and scanning electron microscope. Palynological analysis showed that the pollen grains were generally large, spheroidal and spheroidal-subprolate, radially symmetrical, tricolporate, and reticulate-clavate. The seeds ranged from circular-elliptical to ovate-elliptical in shape, with foveate, foveate-striate, reticulate, reticulate-faveolate, and rugose-foveate ornamentation. The results demonstrated that pollen and seed micromorphology was useful for the taxonomy of these species.
