Abstract: The leaf epidermis of 5 species of ferns of different families were observed and studied by optical microscope.The results showed that there were different appendages on the surface of their leaves,and some species had no appendages;the 5 kinds of ferns had 8 kinds of stomatal types,and they had a multi type phenomenon in the stomatal apparatus,and the stomata were all lower species.The distribution pattern and size are varied,and the micromorphology of the epidermis in the leaf epidermis shows certain differences between families and genera,mainly irregular polygons or regular bars,and the vertical wavy or wavy wavy or wavy shape of the epidermal cells of the epidermis can provide the basis for the systematic classification and evolution of the ferns.

Key words: pteridophyte, leaf epidermis, micromorphology, blotting
