Ultrametric chronograms showing divergence time dating and biogeographic results based on the combined plastid DNA phylogeny. Scale bar at bottom indicating branch length of 2 Mya. Mean divergence age given on nodes. Bars on nodes indicate the 95 % HPD for divergence ages. Pie charts show probabilities of ancestral area reconstructions, colors of pie slices defined in legend. The bottom chart summarized the biogeographic event through time. The Sinomartagon I clade was highlighted for its conflict position compared to the ITS result in Additional file 1: Figure S1
