Abstract

The epidermal structure of Gnetum gnemon leaf blade has been examined. Its description including estimation of the size and shape of epidermal cells, stomatal types, their spectrum and stomatal index is provided. A lot of aborted stomata that accounts for a quarter from the total number of ones in epidermis were detected. The comparison of definite parts of blade showed that they are similar in spectrum of stomatal types and ratio of differentiated and aborted stomata. It makes an assumption that a majority of aborted stomata develop from part of meristemoids, which emerge in epidermis in the period of mass initiation of paracytic stomata. Refs 25. Figs 4.
