Fig. 4 a in Species tree phylogeny, character evolution, and biogeography of the Patagonian genus Anarthrophyllum Benth. (Fabaceae)

Fig. 4 a Calibrated species tree of Anarthrophyllum. Values on the and pie graphs on nodes report probabilities after BBM analysis for rebranches represent statistical support (PP). Numbers given for each constructions. The map shows the biogeographic regions. Vertical bars node are the estimated (median) divergence time in million years; black indicate major clades explained in the text. b Posterior density plots of bars indicate 95% highest posterior densities over the median value. divergence times for the estimated origin of Anarthrophyllum and main Current distributions are indicated by the circles before the species names, clades. QU: Quaternary. PLI: Pliocene
