Abstract: Leaf epidermis of 6 species and 13 populations of Sanicula were observed under light microscope and some quantity index was measured by analyses system of microphotograph. The results revealed that the epidermal structure is the same type: Almost adaxial epidermis are polygonal shapes and their anticlinalwalls are mainly straight-arched, abaxial epidermis are irregular and their anticlinalwalls undulate to sinuate. The stomata are scattered and anisocytic. But the types of anticlinalwall and the proportionment of length to width of stomatal aperture ect. are different among species. Leaf epidermal morphology may verify the systematic relationships and classification of Sanicula.

Key words: Sanicula L., leaf epidermis micro-morphology, taxonomical significance
