FIGURE 1. Phylogenetic relationships within Marattiaceae resulting from the BI (50% majority-rule consensus tree) and MP analyses (strict consensus tree) based on the plastid region trnSGG. Values above and below branches indicate the support values for the BI and MP analyses (PP/BS, respectively), with thick branches for the most robustly supported (PP>0.95 and BS>80%). Dotted lines are not retrieved in MP tree. Names of the six marattioids genera are reported on the right. Bold taxa are from the Western Indian Ocean area and were sequenced for the purpose of this study.
