Parinari curatellifolia

Parinari curatellifolia (Bambara: Tutu; Yoruba: Ìdòfún) is an evergreen tropical tree of Africa, found in various types of deciduous woodland most frequently in poorly drained areas and inland at moderate altitudes. It is also known as mmupudu (by Tswana-speaking South Africans), mupundu or mobola plum after the fruit, which is considered tasty and causes the tree to be spared when woodland is cleared for cultivation. It grows in the Guinea Savanna region of West Africa, from Senegal across to Chad, then in seasonal woodland across the equator through Kenya and the eastern side of the continent, and from there in deciduous Miombo woodland inland to Zambia and Zimbabwe. Its southernmost reach is just outside the tropics in South Africa, at about 25°S....read more on Wikipedia.
