Abstract: The present paper deals with pollen morphology of 19 species belonging to Cyclobalanopsis and of 31 species belonging to Quercus from China. All pollen grains were examined under light microscope and scanning electron microscope, and those of 4 species of Cyclobalanopsis and of 8 species of Quercus were examined under transmission electron microscope. Pollen grains of Cyclobalanopsis are spheroidal or subspheroidal, 25.2(18.9-31.5) ×23.1 (16.8-27.3) μm in size. Mostly 3-colporoidate, rarely 3-colpate or 3-colporate. The exine is 2-layered, 1.1-1.9 μm thick, sexine thicker than nexine, finely granulate under LM, granulate, spinulate, verrucate under SEM. Pollen grains of Cyclobalanopsis and of evergreen members of Quercus are very similar to each other in size, aperture and ornamentation of exine, but there are some differences in pollen grains between Cyclobalanopsis and deciduous members of Quercus. Therefore, Pollenmorphology supports the treatment of Cyclobalanopsis as a subgenus of Querc
