Phylogeny of Convolvuleae. a) Map depicting the areas of endemism for Convolvuleae delimited using UPGMA analysis. b) Dated phylogeny of Convolvuleae inferred in beast from analysis of the concatenated ITS, matK and rbcL dataset. Node bars represent 95 % HPD estimates. Scale bar represent millions of years before present. Coloured branches and taxon names indicate the distribution area inferred in Lagrange, as shown in Fig. 1a. Black branches indicate ambiguous areas (less than 0.2 lnL difference between first and second most likely distribution). Grey branches indicate a multiple area distribution. Numbers at the top-left of nodes are referred to in Table 1. * indicate the location of calibrated nodes. Black circles on nodes indicate nodes with Bayesian Posterior Probabilities of at least 0.95
