Abstract: In order to explore the systematic and taxonomic significance of leaf epidermal micromorphological characteristics in Sanicula, the leaf epidermal micromorphological characteristics of 11 species(13 populations) of Sanicula were studied by scanning electron microscopy. The micromorphological characteristics of leaf epidermis of 11 species of Sanicula were stable, the adaxial epidermal cell comour were mostly unclear, dense stripes or sparse stripes in primary waxy ornamentation, and the granula were adhered to the epidermis. All the abaxial epidermis have stomata, the ornamentation is uniformly distributed around stomata, and almost stomatal outside ornamentation have granular. There are some differences in the micromorphological characteristics of the leaf epidermis such as the secondary ornamentation, the stomatal ornamentation, and the inside ornamentation of the stomata. The above research results can provide important data for exploring the definition and interspecific relationship of Sanicula.

Key words: Sanicula, leaf epidermis, taxonomy, micromorphological feature
