  1. Polyscias and Osmoxylon were excluded from this analysis because the mean and standard deviation could not be calculated from single samples. dS: synonymous substitution rate; dN: nonsynonymous substitution rate.
  2. *Each value represents the mean and standard deviation of the substitution (mean ± standard deviation), with the greatest value shown in bold.
