Fig. 3.

Spatiotemporal evolution of Equisetum as inferred by the stratified DEC model (M1) (results for mode M0 are shown in Supplementary Data Fig. S2). Pie charts at nodes indicate the relative probabilities of ancestral ranges. Vertical dashed grey lines separate the four time slices (TSI to TSIV). Inset maps represent the palaeogeographic configuration of land masses at each time slice, with the main inferred dispersal events represented with arrows. Inferred dispersal (x→y), vicariance (x/x) and peripheral isolate speciation (x\xy) events are represented. RL, relative likelihood.
