Additional file 2: of Unidirectional transitions in nectar gain and loss suggest food deception is a stable evolutionary strategy in Epidendrum (Orchidaceae): insights from anatomical and molecular evidence

Figure S2. Time-calibrated tree of the Orchidaceae, focusing on the subfamilies Orchidoideae and Epidendroideae, based on matK and rbcL plastid regions, estimated using BEAST software. Thin branches indicate posterior probabilities below 0.9. Circles indicate age-constrained nodes. The yellow circle indicates the calibration point for subtribe Goodyerinae (Pachyplectron–Dossinia), the blue circle indicates the calibration point for Epidendroideae, and the green circle indicates the calibration point for the Higher Epidendroids. Numbers at nodes represent median ages in millions of years (Ma). (PDF 665 kb
