A Leaf Epidermis Study on Seven Species of Scleria in Fujian

Micromorphological characters of leaf epidermis of 7species of Scleria in Fujian were examined by LM and SEM.Under SEM,itwas described such as cuticularmembrane,wax ornamenta- tion and epidermal hairs.The stomatal size,stomatal density and stomatal index were measured and counted under L M.The results show thatthe characters such as shape and pattern of anticlinal walls of epidermis cells,culticular membrane,wax ornamentation and silica bodies are less important be- tween species.The featuresof stomatal density,stomatal index,stomatal size stomatal distribution and epidermal hairs possess the classific value of species.
