For each genus divergence values were calculated as base pair substitution differences between species pairs. The highest divergence value for each species pair across the nine plastid regions is indicated in boldface. Values for ITS are included for comparison. Missing values are the result of poor amplification success. For the list of species sampled, voucher data, and GenBank accession numbers see Table 3.
