| Abstract: | In this paper,the leaf epidermal features of Rorippa and two representive species of two related genera are sfudied under light microscope and scanning electron microscope.The stomata types of Rorippa are mostly tricyic type,Anomocytic type in the minority.there are stomata in upper and lower epoidermis in random.The lower epidermal wall is more curved than that of the upper epidermal.There are striations on upper and lower epidermal cutical.Stomata index may be regarded as taxonomic foundation among species.By means of comparative investigat tion,the stonata type of Nasturtium is more evolutional Tetracytic type,Corsamine is similar to Rorippa in leaf epidermal features. |
