Abstract: The leaf epidermis structures of seven species in the genus Euphorbia from Anhui province in China , have been examined with LM and SEM . The shapes of leaf epidermal cells are usually irregular or polygonal and the anticlinal walls are straight , arched , sinuolate, sinuous or sinuate . The stomata apparatus is anomocytic type and some species have simple or multicellular hairs which have neoplasitic process under SEM . And the cuticular membrane of leaf epidermis is scaly or granular under SEM . The result shows significant micromorphological differences of leaf epidermis of the seven species and it is taxonomically helpful for the identification of some species with similar leaf morphology .
