Abstract:: Taking Cypripedium macranthum,Cypripedium guttatum,Cypripedium calceolus,Cypripedium shanxiense, Cypripedium ventricosum, Cypripedium macranthum Sw.f of 6 Cypripedium species which distributed in Changbai mountains as test materials,the characters of leaf epidermis from them were studied.The results showed that the leaf epidermis cells of 6 Cypripedium were irregular shapes，the anticlinal walls were waving undular，but the waveforms were different.Stomatas were randomly distributed on the lower epidermis.The stomata of Cypripedium shanxiense was oval，the rest species were round or nearly round.All of the leaf epidermis were pubescent,the pubescences of Cypripedium macranthum and Cypripedium macranthum Sw.f.had 4 sections，the rest 3 sections.The blade grain of Cypripedium guttatum were wavy，the rest ditch lines.Different characters of leaf epidermis could be the basis classifications of inside.
