Phylogeny based on the majority-rule consensus tree derived from Bayesian analysis of our tribe-wide nrITS dataset. Figures following the binomials are our DNA extraction numbers. Support values displayed on the branches follow the order BPMP/BPML/PPBI (“-” indicates support values of less than 50 and “*” indicates a support value of 100). The scale bar denotes the expected number of substitutions per site in Bayesian analysis. Arrows indicate the weakly supported deep nodes. Colour blocks denote the monophyletic, narrowly delimited (s.s.) genera in the East Asia Clade of subtribe Orchidinae plus selected Eurasian species of subtribe Orchidinae and of subtribe Habenariinae (stippled grey). Only the Eurasian Orchidinae have been subjected to genus-level re-circumscription according to monophyly
