Abstract: Pollen grains of 13 species of Phyllanthus Linn. (Euphorbiaceae) were examined by light microscope (LM) and scanning electron microscope (SEM). The result showed that five types of aperture can be divided, namely 3-colporate, 4,5-colporate, multi-colporate, pantocolpate and pantoporate, which are more of less related to the sections divided by Li in Flora of China (Vol.44),though they are not very identical with the sections. The aperture types have some values in the division of sections. All species have reticulate exine sculpture and there is no obvious sculpture difference among sections or species, although the sculptures can be divided into gross, middle and fine reticulations among species.
