Description
Morning glories generally exhibit low levels of hybridization between species. An exception to this notion is the monophyletic syngameon Ipomoea section Batatas. Strict molecular phylogenetic analyses have left the evolutionary relationships of this system unresolved. Thus a population geographic approach may be more appropriate. Statistical phylogeographic methods can be used to elucidate hybrid zones, introgression, and geographic reasons for isolation. These implications can further invoke complex patterns of species distributions and speciation. Hence our intent is to parameterize the evolutionary relationships among population samples of the named species in I. sect. Batatas, such that we might reconstruct their evolutionary history.
