The leaf structure of Gnetum montanum Markgraf (Gnetaceae)
The structure of leaves of G. montanum has been investigated. The variability and the correlations between its characteristics have been estimated. There were detected: low level of the variability and high relatedness with other characteristics of the leaf of number of cell proliferations in epidermis, fixity and low isolation of stomatal index, flexibility and isolation of water balance characteristics, conservatism of mesophyll characteristic. The structure of this liana has been compared with G. gnemon, which is a tree. The ones are similar according to their structure and level of variability. Using principal component analysis have shown that differences between leaves of these species are quantitative. Refs 31. Figs 4. Tables 3.
