Trends in allopolyploid versus diploid floral divergence. Trends in evolution for extant allopolyploid floral limb shape (a), extant allopolyploid tube length and width (b), reconstructed allopolyploid floral limb shape (c), reconstructed allopolyploid tube length and width (d), diploid floral limb shape (e), and diploid tube length and width (f). Lines represent vector from the progenitor midpoint to the allopolyploid mean in (a-d) and the origin represents the progenitor midpoint. Young allopolyploids (0–0.7 myo) shown in red; older allopolyploids (1.4–4.3 myo) shown in light blue. In (e-f), lines represent the difference in reconstructed values between successive nodes on the tree and the origin represents the older node. Labels in the quadrants denote the phenotype toward which the vectors in that quadrant are evolving
