A Localities of the 39 Magnoliaceae species selected from the whole distribution area of the genus. B Localities of the 29 Neotropical species included in the analysis and the subregion delimited for this study. Markers indicate the section to which each species belongs. Colors in B) represent the operational areas defined for the ancestral range reconstruction based on the biogeographical provinces of Morrone and Löwenberg-Neto. In addition to the Neotropical areas, the Nearctic region and Asia were also considered as operational areas for the analysis.
