Phylogenetic tree constructed based on 38 complete chloroplast genomes. The BI tree and the ML tree are shown together, and posterior probabilities (PP) and bootstrap searches (BS) are displayed on the branch and are indicated by "-" for PP < 0.50 or BS < 50. The different background colors indicate the three main branches, which correspond to Clade B, Clade C, and Clade D in the study by Kong et al. 13. The chloroplast genomic data added in this study are shown in red font.
