Maximum Likelihood phylogenetic tree of Gastrochilus, including 50 taxa, based on the combined nrITS and four-plastid (matK, psbA–trnH, psbM–trnD, and trnL–F) marker dataset. Values before slash indicate Bayesian posterior probabilities and numbers after slash indicate ML bootstrap supports for major lineages. An asterisk (*) indicates that a node is not supported in the analysis. The two accessions of the inferred new species are highlighted in red, and colors of terminal nodes correspond to the six sections of Gastrochilus defined in Zhang et al. (2024).
