Foliar micromorphological study of plants describes the distinct structure and functions of foliar tissues. The structural analysis of G. superba epidermal tissues and leaf architecture revealed the stomatal type, morphology and their orientation, cuticular wax deposition, crystal arrangement and venation pattern. The stomatal density was observed maximum on abaxial epidermis. The epidermis contained ordered stomatal pattern with anomocytic stomata. The stomatal density and stomatal index was 12.0 and 29.0 respectively. The parallel lower order veins and perpendicular higher order veins form a grid-like network of venation pattern in G. superba. Con-vallaria type of cuticular wax was observed. The results of the foliar features could be applied in systematic studies and also to predict the environmental factors responsible for the development of certain leaf parameters.
