Bayesian factor species delimitation for Musa itinerans varieties using 1201 unlinked loci. (a) the five taxa species tree determined by the most marginal likelihood estimates of different species models. Bayesian posterior probability, ancestral population size, divergence time are separated by two slashes; the 95% highest posterior density (HPD) for divergence times are highlighted using horizontal grey bars; (b) DensiTree shown for all trees of the Markov chain Monte Carlo method with a burn-in of 5000 trees, and higher levels of uncertainty are represented by lower densities
