Table 1 Crown group ages (in million of years) estimated for the family Orchidaceae, the five orchid subfamilies, the 'Higher Epidendroids' and the subtribe Goodyerinae, as compared to previous estimates using Penalized Likelihood [4].

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)

Clade Ramirez et al.[4]: Penalized Likelihood This study: BEAST, same data set as Ramirez et al.[4] This study: BEAST, with additional taxa and calibration points
