Abstract: Leaf epidermis of 2 species in genus Sauromatum Schott were examined under light microscope and scanning electron microscope (SEM) and compared with that of 13 species in genera Typhonium,Pinellia and Arisaema in the same tribe Area of Araceae.The result reveals that the characters of leaf epidermis between the several genera generally are very similar.However,some of the characters in the species of the same genus are variable and can be used to identify its species.The characters of leaf epidermis support to merge Typhonium kunmingense into Typhonium calcicolum. The stomata apparatus of 15 species are all brachyparacytic types with 2 subsidiary cells. This type of stomata apparatus is considered more evolutional than that with more than 2 subsidiary cells which existed in majority tribes of Araceae. This also verify some taxonomists' viewpoint that tribe Area is more evolutional in family Araceae.
