Abstract The pollen morphology of 9 species, 9 genera and 3 families (Rhoipteleaceae, Juglandaceae and Betulaceae) has been examined under light micro-scope. The 3 species (Rhoiptelea Chiliantha Diels et Hand.-Mazz., Juglans sigillate Dode. and Betula platyphylla Suk.) were observed under scanning electron microscope. The form of pollen grains on the Rhoipteaceae and Betula L. are all oblate. The polar view was observed. lt likes an obtuse triangle. The type of aperture are all composite aperture and the thickness of extine have arched hyperplasia between porus. The sculpture of extine show finely granulate. The form of Juglandaceae show polygon or triangle and the type of aperture show dispersive porus. The present article has discussed the palyno1ogical data main1y in relation to the classification and systematic position of Rhoipteaceae.
