Maximum likelihood phylogeny of tea plants with information of morphospecies assignments, information of collection sites, and delimited MOTUs. The branch colors represent the QS scores (QC/QD/QI). Red represents full or strong support (QC ≥ 0.5), purple represents moderate support (0.2 ≤ QC < 0.5), blue represents weak support (0 ≤ QC < 0.2), and green represents counter support (QC < 0), according to Pease et al. (2018). The geographical distribution of collection sites is marked on the voucher number (sample name) with different colors. Taxa names in red indicate monophyly and taxa names in black indicate non-monophyly. Red solid boxes besides taxa names indicate agreement between molecular species delimitation method and morphospecies assignment, while blue solid boxes indicate disagreement. Hollow boxes indicate the final MOTUs
