Studies on Leaf Epidermis Micromorphology of uphorbia from Anhui Province

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.
