V. longifolia tetraploid vs. V. spicata tetraploid	0.40	0.81 ± 0.04	<0.01
V. longifolia diploid vs. V. spicata tetraploid	0.41	0.78 ± 0.05	<0.01
V. longifolia diploid vs. V. spicata diploid (west)	0.46	0.78 ± 0.06	<0.01
V. longifolia tetraploid vs. V. spicata diploid (west)	0.40	0.77 ± 0.04	<0.01

The mean, the standard deviation (SD) of the D value, and the p-values were derived from the distribution of D values from 100× pseudoreplicates.
