Abstract:By using light microscope and scanning electronic Microseope, in the present study, the characters of leaf epidermis of Gymnotheca Decne. and its affinite genera, Saururus Linn., Houttuynia Thunb. (Saururaceae) and Zippelia Blame (Piperaceae) , totally 4 genera 5 species, have been observed and compared. It shows that there are differences in the features, such as the types, the size, the frequen- cy and the index of stomata, the types and the distributions of trichomes, the shapes and the arrangements of epidermal cells, and so on. It was found that there is a kind of multicellular structure which like hydropoten.Its occurrence shows that there are certain relationships between Piperales (including Saururaceae and Piperaceae) and Nymphaeales and Ranunculales.
Keywords:Characters of leaf epidermis  Hydropoten  Cymnotheca  Houttuynia  Saururus  Zippelia
