Abstract: [Objectives] To discuss the relationship between left epidermis structures and drought resistance. [Methods] The leaf epidermis of Callisia repens was studied by optical microscope. [Results] The upper and lower epidermal cells of the leaves of Callisia repens arranged closely, and no cell gap was arranged. The morphology of the epidermal cells was hexagonal, few pentagon or heptagon, the equivalent elliptical aspect ratio was 1.20, the vertical wall was straight and there was no stomatal distribution. Compared with the epidermal cells, the morphology of the lower epidermal cells was irregular. The equivalent elliptic aspect ratio was 1.35, and the vertical wall was smooth and curved. The mean oval aspect ratio of the stomatal guard cells was 1.42, the average stomatal density was 11.79/mm2, and the average stomatal index was 17.21. [Conclusions] These characteristics provide the theoretical basis for the drought resistance of Callisia repens and the ornamental plants as roof greening.
