FIGURE 4. The phylogenetic tree using MrBayes based on the sequences of rbcL, the intergenic spacer regions of trnL(UAA)-trnF(GAA), psbC-trnS(UGA), trnW(CCA)-trnP(UGG), and rbcL-atpB. Numbers on branches are support values PPBI/ML (Bayesian inference posterior probabilities / maximum likelihood). Dash (-) indicates nodes with PPBI or ML <50%. "//" indicates that the branch length of the outgroups is shortened.
