Fig. 4.

Plastid haplotype networks and distribution of those haplotypes along the transect for I. bourgonii (A), I. alata (B), I. ruiziana (C), I. alba (D), I. umbellifera (E), I. marginata (F), I. sapindoides (G), and I. edulis (H). In the networks, each circle represents a unique haplotype, and each line represents a single mutation (insertion-deletion or substitution). Black circles represent unsampled haplotypes. Haplotypes are not shared between species and are color-coded separately for each species. On the maps, a hollow circle indicates that the species was not found at a given site, and a gray circle indicates the species was present at that site, but DNA sequences were not obtained.
