Systematics Fuller, Daniel [1], Hughes, Mark [2], Moonlight, Peter [2]. Phylogenetic Incongruence in Begonia L. The increased availability of DNA sequences has revolutionized the field of molecular phylogenetics. However, the increase in available data also increases the opportunity for statistically significant incongruence to affect multigenic phylogenies. The source of incongruence between phylogenies can vary from sampling error to systematic error to different evolutionary histories. Begonia is a mega-diverse genus of approximately 1800 species most of which are narrow endemics. Originating in Africa, Begonia has since dispersed throughout the tropics and undergone several rapid radiations making it an ideal study group for evolutionary botany. A previous framework phylogenetic study of Begonia has shown significant levels of incongruence between the mitochondrial and chloroplast datasets. Using Bayesian Inference methods, phylogenies of Begonia mitochondrial and chloroplast DNA were created using representative species from all major clades covering the entire pantropical range. The resulting phylogenies were compared and instances of well supported incongruence noted.
