Psoraleeae_Chronogram_Fig1

Chronogram representing the maximum clade credibility tree estimated in BEAST based on total evidence across eight DNA regions using mixed models. Mean divergence dates shown for key nodes. Gray bars represent the 95% high posterior density credibility interval for node age. * nodes used as calibration points. Arrow denotes shift from/to mesic (m) or xeric (x) habitat hypothesized along the lineage shown. Ingroup: P = Pediomelum; Ps. = Psoralidium; R. = Rupertia; O. = Orbexilum; H. = Hoita. Outgroup: C. = Cullen; Ot. = Otholobium; B. = Bituminaria; G. = Glycine; Ph. = Phaseolus; D. = Desmodium. Numbers following taxon names represent accession numbers with reference to previous work
