The Microsporo genesis and the development of Male Gametophyte in Cinnamomum paueiflorurn were studied through the traditional paraffin section methods.The results show that the anther is tetrasporangiate and its mature wall belong to the basic type;the amoeboid tapetum is monotypic with binuclear cells,which flow into the anther sac during the meiosis of microporocyte;the cells are absorbed by the developing pollen at the early of male gametophyte;the endothecium develops U-and V-shaped thickenings on the inner tangential and radial walls;the epidermis degenerates;cytokinesis is of successive type and the isobilateral microspore tetrads are formed;pollen grains are mainly 2-celled.
