Figure 5.

(A) Natural logarithm of area (cm²) vs. natural logarithm of vein to blade ratio. (B) Residuals from the model of natural logarithm of area (cm²) vs. natural logarithm of vein to blade ratio, as indicated in panel A, vs. distal lobing. In both panels, each leaf (n = 2632) is plotted with the color of the point indicating the distal lobing value. The natural logarithm of leaf area varies significantly as a function of the natural logarithm of vein to blade ratio, and residuals from that model vary significantly as a function of distal lobing. The adjusted R ² for each model is indicated on the plots.
