Abstract: Pollen grains from 6 species of Stipa L.in Inner Mongolia were collected and observed by scanning electron microscope.The results showed that there were differences among the pollen grains in terms of size, diameter of pore, protuberace of pores, annulus and suface ornamentation.The divergence of pollen morphology were correlated to regional distribution of the plants.

Key words: Pollen grains, Pollen morphology, Stipa L
