Knowing the geographic origin of certain plant groups is important for genetic improvement and conservation. We address the history of the economically important gourd family, Cucurbitaceae, using a multi-gene phylogeny for 114 of the 115 genera and 25% of the 960 species.
Our results reveal an Asian origin in the Late Cretaceous, followed by the repeated spread to Africa, America, and Australia via transoceanic long distance dispersal (LDD).
North American cucurbits stem from at least seven range expansions of Central and South American lineages; Madagascar was colonized 13 times from Africa; Australia was reached twelve times from Southeast Asia.
