Results showed that all leaves consisted of epidermis, chlorenchyma, aquiferous tissue and vascular bundles. The leaves had the xeromorphic characteristics, including thickened epidermal cell wall, thickened cuticle, sunken stomata and well_developed aquiferous tissue. With the exception of this, there were remarkable differences in leaf structure among the six species.
