Phylogenetic tree inferred by MP A and BI B analyses based on the combined matrix of two plastid loci (rpL16 intron and ndhA intron) and nuclear ITS. Maximum parsimony bootstrap A and Bayesian inference posterior probability values B are labelled on the branches; when the number is below 80 and 0.80 in maximum parsimony bootstrap and Bayesian inference posterior probability, respectively, the branches are labelled—.
