Uvaria is a genus of flowering plants in the soursop family, Annonaceae. The generic name uvaria is derived from the Latin uva meaning grape, likely because the edible fruit of some species in the genus resemble grapes. Species are distributed throughout the Old World tropics. This large genus had about 150 species, but recent molecular analyses have revealed that several smaller genera belong within Uvaria, increasing its size. These are climbing shrubs or small trees. The flowers are borne singly, in pairs, or in small clusters. There are six petals in two whorls and many stamens.
