Scaling of xylem vessels and veins within oak leaves

An examination of the scaling of the leaf xylem in ten temperate oak species to test general models of plant vascular architecture, based on scaling of pipe diameters in order to minimize hydraulic resistance within the xylem, which have neglected to consider the variations in leaf hydraulic properties.
