Abstract: The anatomical structure of leaves of Emmenopterys henryi Oliv. was investigated by wax-slides and photo-microscopy. The observed results indicate that the leaf belongs to typical bifacial leaf. Each epidermis consists of a row of irregular epidermic cells which are arranged closely and the horny layers of the cells are thin.The stomata only exist in lower epidermis covered by sparse cellulous epidermal hairs, and their type is paracytic. The mesophyll is very rich. Its palisade tissue is composed of 1~2 layers of cylindrical cells. The ratio of the palisade tissue to the spongy parenchyma is 1:2.2.The midrib is conspicuous.The characters mentioned above shows that it is adapted to the environments in which they live.

Key words: Emmenopterys henryi Oliv., leaf, anatomical structure
