Three types of cuticular thickening at the polar region of the guard cells are observed: slight cuticular thickening; rod-shaped culicular thickening and rarely T-shaped thickening.With data obtained from the former research and personal observation, the cladistic methods were employed for the phylogenetic analysis of data and trees were rooted byout-group comparison using, the related genus Kadsura. as result, a new system of the genusSchisamdra Michaux was reconstructed, and Schisandra Michaux was subdivided into 2 subgenus, 3 section, 2 series 10 species in this dissertation.
