Map of the transect. The color of the localities within the map corresponds to the crossing groups of populations determined by the crossing experiment (Figure 2). The colored bars outside the map refer to the genetic clusters inferred by STRUCTURE with no-admixture. The pie charts outside the map indicate the proportion of normal (blue) and androecium-mutant (red) flowers per population. The names of populations follow those given in Table 1.
