Fig. 6

Phylogenetic trees inferred from maximum likelihood (ML) and Bayesian inference (BI) analyses based on the complete chloroplast genomes. Numbers near the nodes are ML bootstrap support values (BS, left of the slashes) and Bayesian posterior probabilities (PP, right of the slashes). 100% BS or 1.00 PP are indicated by asterisks. Incongruences between the BI and ML trees are indicated by dashes. Hu’s classification is illustrated by color graphic pattern. Recognized groups (major clades) were also marked by the right-hand black bar
