Divergence depends on the strength of selection and frequency of gene flow between taxa, while reproductive isolation relies on mating barriers and geographic distance. Less is known about how these processes interact at early stages of speciation. Here, we compared population‐level differentiation in floral phenotype and genetic sequence variation among recently diverged
Using target enrichment enabled by the Angiosperms353 probe set, we assessed genetic distance among 50 populations of four
We document that
Patterns of genetic distance in
