Lagrange optimisations and beast minimum age estimates for key nodes in the Convolvuleae analysis. Node numbers are labelled in Fig. 1b. Lagrange splits refer to areas shown in Fig. 1a in the format x/y where x relates to the top branch, and y relates to the bottom branch exiting the labelled node. Log likelihoods (lnL) and relative probabilities (Rel. Prob.) are given for each Lagrange optimisation within two lnL of the most likely split optimisation. Bayesian Posterior Probabilities (BPP), mean node ages and 95 % highest posterior density (HPD) estimates inferred in beast are given for each node
