The pollen morphology of 15species of Sanicula was observed by light microscopy（LM） and scanning electron microscopy（SEM）. The pollen size of 15 species of Sanicula was（28.51-54.29） μm-（12.23-28.98） μm， and the ratio of polar axis to equatorial axis（Polar axis/Equatorial axis） was 1.48-2.46 with a three-hole ditch. Views of pollen grains include near-rectangular， equatorial contraction， long ellipse etc. Among them， near-rectangular and equatorial contraction are the majority. Polar views are round or triangular. Under the scanning electron microscope， the outer wall surface is reticular. Our studies support that in the Saniculoideae（Apiaceae）， the pollen of the genus Sanicula has moderately evolved and relatively evolved morphological features. The pollen morphology can provide palynological evidence in the classifying individual species.
