Graph showing the density of venation in representative Portulaca species. For two species, P. amilis and P. biloba, vein density is shown for both sides of the leaf, adaxial and abaxial (ada and aba on graph). For P. oleracea, two accessions were studied: *, seeds from Pullman, WA, USA; and **, seeds from USDA PI 0121921. n≥10. Different letters indicate significant differences between species and leaf sides, P≤0.05.
