Abstract: Pollen morphology of 25 species of 8 sections of the genus Arisaema was studied by means of scanning electron microscope.In the 25 species,12 species were examined for the first time,and 11are endemic to China.Pollen morphology of the species is basically uniform,i.e.spherical,inaperturate,intectate and spinulose.However,the diameters of pollen grains,the length and density of spinule and ornamentation among spinules are variable and significant in identification of species.

Key words: Arisaema
