The Influence of Branch Order on Optimal Leaf Vein Geometries: Murray’s Law and Area Preserving Branching
Figure 3
Frequency distribution of the area ratio for 1,514,771 individual vein junctions across all leaves.
The mean and median are equal to the expectation for Murray’s law when daughter branches are symmetric. The distribution spans the range of expected values from 0 to 2, which includes area-preserving branching as well.
