From: Reassessing the temporal evolution of orchids with new fossils and a Bayesian relaxed clock, with implications for the diversification of the rare South American genus Hoffmannseggella(Orchidaceae: Epidendroideae)

Figure 2

Time-calibrated tree of the Orchidaceae based on plastid DNA sequences ( mat K and rbc L) obtained with BEAST, including two new calibration points ( Dendrobium and Earina ), and with the root calibration on the stem node of Asparagales. Numbers at nodes are median ages in million of years (Ma). Dashed branches indicate nodes with Bayesian posterior probabilities below 0.90. Circles indicate age-constrained nodes; the yellow circle indicates the root node, the purple circle indicates the internal calibration point for subtribe Goodyerinae (Pachyplectron - Dossinia), the blue circle indicates the new internal calibration point for Dendrobium and the green circle indicates the new internal calibration point for Earina.
