Abstract :Pollen morphology of 23 species of taxonomically difficult genus Aethionema W.T.Aiton was examined by light microscopy insert ignore into journalissuearticles values(LM); and scanning electron microscopy insert ignore into journalissuearticles values(SEM);. Pollen grains have showed significant variation in aperture number and type. Generally pollen is tricolpate, but tricolpate-syncolpate, tetracolpate, or merely syncolpate apertures also occur and make a heteromorphic assemblage. Pollen shape is prolate, prolate-spheroidal, subprolate, spheroidal or suboblate, and pollen ranges from 9.4 to 29 µm insert ignore into journalissuearticles values(P);, 6.2 to 23.9 µm insert ignore into journalissuearticles values(E);. Five main pollen types were identified based on the sculpturing of the exine. The pollen shape, size, surface ornamentation, muri and lumina shape and size are found as important and useful features for distiguishing of the taxa
