Results of TreeMix analysis of the phylogenic relationships among the seven clusters defined by sNMF analysis. C. myrtifolia (MYR) and C. bernardiniana (BER) served as outgroup populations. E eastern cluster, NE north-eastern cluster, SE south-eastern cluster, C central cluster, SW south-western cluster, W western cluster, NW north-western cluster. a Maximum-likelihood tree of 323 C. mauritiana divided into the seven population groups included in the analysis. Horizontal branch lengths are proportional to the amount of genetic drift that has occurred in each branch. b Residual heatmap from the tree in a. Pairs with high residual values are candidates for migration events. c Maximum- likelihood tree that best fits the data and its associated residual heatmap d. The migration weight indicates the proportion of ancestry deriving from the migration edge
