Maximum Likelihood phylogenetic tree reconstructed from plastome sequences of the tribe Arundinarieae. Numbers along branches indicate the Maximum Likelihood bootstrap values (MLBP) and Bayesian posterior probabilities (BI). * means MLBP/BI=100/1.00. The Roman numbers on the right of this tree correspond to those lineages recovered in previous studies (Yang et al. 2013). The branch in red (MLBP/BI = 88/1.00) denotes the clade containing Yushania dezhui and its relatives.
