Effects of two anatomical parameters related to vertical distance between veins and the epidermis on Kox: the ratio of the distance between the BS and the upper epidermis to the distance to the lower epidermis (A); and total leaf thickness (B). Solid lines are mechanistic relationships obtained by varying the parameters shown on the x axes in the model while holding all other parameters constant. White circles are values for each of 14 species, and dashed lines are the cross-species correlations between the parameters on the x axes and each conductance. r2 and P values shown are for the cross-species correlations.
