This study provides the palynological literature for morphologic features of almost all pollen types of Euphorbiaceae, including 33 species in 21 genera. Size, shape and surface ornamentation of pollen types in subfamilies were analysed and compared. Pollen of each subfamily have distinctive morphological features that can be used for identification. Some genera (e.g., Mallotus, Alchornea, Phyllanthus) have unique pollen types, which can be identified to genus or even species level. This study provides classification of pollen types of Euphorbiaceae subfamilies and new references for the database.
