FIGURE 1A. Phylogeny of more taxa reconstructed using maximum likelihood based on the analysis of rbcL sequence, basal part. Branch length corresponds to the estimated number of substitutions (see bar). Values above branches correspond to the maximum likelihood bootstrap values. Only bootstrap values>50% are shown. Species marked with an oval are focus in this study. Abbreviations (clade names following Windham & al. (2009): B, bommeriid clade; M, myriopterid clade; N, notholaenid clade; P, pellaeid clade; H, hemionitid clade. The inlay figure shows the entire phylogram; the arrow indicates where it has been split into Fig. 1A and Fig. 1B.
