From: Unidirectional transitions in nectar gain and loss suggest food deception is a stable evolutionary strategy in Epidendrum (Orchidaceae): insights from anatomical and molecular evidence

Fig. 3

Time-calibrated tree of Epidendrum based on one nuclear and five plastid regions estimated with BEAST. Arpophyllum, Cattleya, Encyclia, and Meiracyllium species were used as outgroups. Thin branches indicate posterior probabilities lower than 0.9. Numbers at nodes indicate median ages in millions of years (Ma). Node bars indicate the 95% HPD lower and upper bounds in Ma. Circles indicate age-constrained nodes; the purple circle indicates the calibration point for Laeliinae, and the red circle indicates the calibration point at the Cattleya + Epidendrum + Meiracyllium clade. GenBank accession numbers of nuclear (ITS) and plastid (matK, rbcL, trnL–trnF, trnT–trnL, and rpl32–trnL) regions are provided in the Additional file 4: Table S1
