Observing on epidermal morphology of Gynostemma mature leaf including 6 species (maleand female plants of 4 species of them) under SEM and on the cross section of 4 species matureleaf under LM show that the shap of epidermal cell, the thickness of cuticle, the amount of wax,the density and the location of the stomatal apparatus, the shape of the outer stomatal ledge are alldifferent accrocding to the different species and its growing range. The foliar structure of thespecies in the dry environment developed much better in water-retaining capacity. Contrary tothese species, the others can only grow in limited range. All these evolve into peculiar shape andstructure that have relative stability in heredity.
