Cucurbitaceae is a large family, which includes many economic species such as melon, watermelons, various gourds, and pumpkins that are of particular importance for the inhabitants of SSA. Many Cucurbitaceous species are eaten in several different forms, as seeds, leaves, fruits and sometimes flowers, by villagers throughout Africa. IPGRI, with national and international partners, has been leading the work on the collection, characterization and conservation, as well as on ethno botany, of Cucurbitaceae in the region.
