Geographical distribution of the 13 Handroanthus impetiginosus populations sampled for genetic analyses and the respective Bayesian clustering of individuals based on 200 putatively neutral SNP loci. Each colour represents the inferred cluster (K = 4) following the figure legends. The size of cluster chart section represents population coancestry for each cluster. Details on the sampled populations are provided in Supplementary File S1 and Table S1
