Abstract

An earlier paper gave a brief account of experiments dealing with the conductive efficiency of certain types of vein systems in foliage leaves. By cutting the blade in various ways it was possible to show some of the advantages and also the disadvantages of different types of venation. The results indicated that larger veins, while highly efficient for conduction along their length, may constitute real barriers to movement across them, especially when interrupted by breaks in the veins, which cuts doubtless lead to leakage. On the other hand, regions free from larger veins showed marked capacity for conduction in all directions. The relatively small veins constituting the islet-borders were found to be capable not only of ready conduction in any direction in the blade but were demonstrably capable of carrying a very great overload.
