摘      要：Pollen grains from 15 species(18 taxa) of the genus Filipendula were examined with light and scan-ning electron *** was revealed that the pollen grains are isopolar,tricolporate,with scabrate or scabrate-microechinate *** pollen morphology was compared with the conventional classification sys-tems of the genus by different authors,and supported Shimizu’s system(1961),in which the genus was divided into three *** monotypic *** is characterized by pollen lacking fastigium and thickened costae *** other monotypic *** differs from others by pollen having larger grain,larger pore size,longitudinally elliptic fastigium and thickened costae *** largest *** is distinguished by pollen having rounded or latitudinally elliptic fastigium and thickened costae *** classification was not supported by the pollen morphology due to insufficient variability.
