Structural differences among the leaves of a single tree are well known and the literature on this subject is extensive. In most of these papers the tissue study was limited to transverse sections of the blade. Some of them included more or less critical analysis of various environmental factors. A limited number gave some measurements of venation but relatively little attention has been given to the inter-relations of the blade tissues, viewed as working unit. Reference is here limited to a few papers that are of interest in this connection and each of them carries a bibliography of related titles.
