Phylogenetic trees constructed by Maximum Likelihood (ML) and Bayesian Inference (BI). The bootstrap values (BS) of ML and posterior probabilities (PP) of BI are listed at each node. (*) represents the node with PP = 1.00/BS = 100. “–“ means the values < 0.50/50. Red background indicates the newly-sequenced unknown Impatiens species A plastomes-based tree B ITS-based tree.
