Calibrated multispecies coalescent of the diploid Hordeum species as calculated with *Beast from all loci excluding NUC. Numbers along the branches are posterior probability values/concordance factors of the clades. Ages (in millions of years) were inferred from the crown clade age of B. distachyon + Triticeae at 44.4 Ma and from the divergence between Hordeum and Triticum lineages at 15.32 Ma (Marcussen et al. 2014); calibration points are depicted by asterisks, divergence dates are reported in Table 4.
