Abstract: The pollen grains of 13 species representing 9 genera of Flacourtiaceae were examined by light microscopy and scanning electron microscopy.These related genera have fairly similar in pollen shape (prolatespheroidal) and tricolporate,though Hydnocarpus with indistinctly tricolporate.The pollen exine sculptures can be divided into 4 types:foveolate,finely reticulate,coarsely reticulate and perforate.Pollen morphology plays a certain role in the circumscription of among related families and different genera.
