Artocarpus (ca. 70+ species) is the third largest genus in the Moraceae family. Species are distributed from South Asia east into Oceania, with the greatest species diversity in Malesia. The genus contains numerous economically important species that are grown in their native regions for timber or fruit. While a few species are grown to some extent outside the native range of the genus, there are two species that are cultivated widely throughout the tropics: jackfruit (A. heterophyllus) and breadfruit (A. altilis). Phylogenetically informed revisionary work of the genus is ongoing. Given the great diversity of inflorescence types and pollination modes within the Moraceae family and the many cultivated Artocarpus species, a phylogenetically informed revision will allow for in depth research on pollination shifts and identification of underutilized crop wild relatives to help conserve diversity and advance crop development.
