Fig. 1

The maximum clade credibility tree for Encyclia sensu stricto and related genera, obtained for a combined dataset (nuclear: ITS, Xdh, PhyC and plastid markers: ycf1, rpl32, and trnL-trnF) using Bayesian inference. Numbers above branches indicate posterior probability and bootstrap support values from maximum likelihood analysis (PP/BS). The scale at the base of the tree indicates divergence times in millions of years ago (Mya), estimated by uncorrelated relaxed molecular clock analysis using the Yule model of speciation. Calibration points follow Givnish et al. [28]. The major clades were indicated by capital letters (A-C) or capital letters and numbers (C1, C2). The smaller subclades were indicated by lowercase letters and numbers
