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 3

Time-calibrated tree of the 'Higher Epidendroids', focusing on the South American orchid genus Hoffmannseggella , based on nuclear ribosomal DNA sequences (nrITS), estimated with BEAST. Thin branches indicate posterior probabilities below 0.9. Numbers at nodes are median ages in million of years (Ma). Node bars indicate the 95% HPD lower and upper bounds in Ma. Inset: Hoffmannseggella endsfeldzii, showing the racemose inflorescence typical to the genus, and brightly yellow-coloured flowers. Photo: ALSG.
