Phylogenetic tree of the Monodoreae specimens, as pruned from the maximum credibility clade tree estimated from 8601 posterior trees inferred based on 32 nuclear loci with uncorrelated molecular clock and fossil calibration in BEAST. Values at nodes indicate the mean age from the posterior probability density, and the blue bar indicates the 95 % highest posterior density interval of the age. All nodes received a posterior probability of 1 except for those indicated by a grey circle. The colour square at the tip indicates the geographical origin of the specimen. Colours follow Fig. 1.
