Figure S1. Chronogram of Lamiales with 95% highest posterior density bars, based on BEAST analyses using four fossils and two secondary calibration points (letters A–F; see Table 1). Bayesian posterior probabilities are indicated above branches when higher than 0.5. The portion of the tree corresponding to Gesneriaceae is shown in Figure 2.

FigureS2. Chronogram showing all the accessions analysed with 95% highest posterior density bars, based on BEAST analyses using four fossils and two secondary calibration points listed in Table 1. Bayesian posterior probabilities are indicated above branches when higher than 0.5. Geological time scale is shown at the bottom. The basal portion of the tree, including all other taxa of Lamiales, is available in Figure S1.

Figure S3. Palaeogeographical model used in the Lagrange analysis, with two time slices reflecting the probability of area connectivity through time. The area codes correspond to A, Tropical Andes (> 1000 m); B, Brazilian Atlantic forest; C, Central America; E, Cerrado; T, Temperate Andes; Z, Amazonian rainforest including lowland Amazonia, Sub-Andes, Guiana shield and northern Venezuela-Colombia; and W, West Indies. Taxa ranging outside America were assigned to either (O) Old World (Africa, Europe and tropical Asia) or (P) south-west Pacific (Australia, New Caledonia, New Zealand and Lord Howe Island).

Figure S4. Cross-validation procedure for the fossil calibrations used in this study. Letters refer to the calibration points defined in Table 1. The orange density plots represent the prior distribution used and the blue density plots give the posterior density obtained when the fossil was not used in the analyses. The large overlap between the prior and posterior densities observed for each calibration point indicates that the fossil calibrations are congruent.
