Niche-cluster membership of 604 data point localities itemized per species of Bulbophyllum clade C (sects. Bifalcula, Calamaria, Humblotiorchis), and outgroups, used as tip-states for the reconstruction of ancestral niche states A, B, and C (see Fig. 4). Note, two clade C species are not included in the present study (i.e., B. cryptostachium Schltr., B. sp. nov. ‘F’)
