A taxonomic monograph of Ipomoea integrated across phylogenetic scales.

Taxonomic monographs have the potential to make a unique contribution to understanding global biodiversity. In this talk, I will describe a global-scale monographic study of the genus Ipomoea that integrates DNA barcodes and high-throughput sequencing with the morphological study of herbarium specimens. Our approach overhauled the taxonomy of this megadiverse group, described many new species and uncovered significant increases in net diversification rates comparable to the most iconic evolutionary radiations in the plant kingdom. It also contributed important information about the origin and evolution of the sweet potato, Ipomoea batatas, and its close wild relatives. Our results demonstrate how the world’s natural history collections can contribute to global challenges in the Anthropocene.
