Abstract: Pollens of 5 species of Magnolia were observed and screened with light microscope(LM) and scanning electron microscope(SEM) respectively; pollen size were measured under LM; and the metrical results were analyzed. The results show that under the LM all pollen appear as oval or close to rotundity, but these species are different in size and shape, and also the distinctions exist in different trees of same species; while under SEM, all the pollens appear as boats, every pollen has a closed sprout channel whose length almost equal to the longer axis of pollen, the characters of pollen surfaces are steadily in same species, but there are some visible differences among pollen of different species and these differences can provide important morphologic basis for classification of species of Magnolia L..

Key words: Magnolia wufengensis L. Y. Ma et L. R. Wang, pollen morphology, taxonomy
