Morinda citrifolia is a tree in the coffee family, Rubiaceae. Its native range extends through Southeast Asia and Australasia, and the species is now cultivated throughout the tropics and widely naturalised.
English common names include great morinda, Indian mulberry, noni, beach mulberry, and cheese fruit.
Despite its strong smell and bitter taste, the fruit is nevertheless eaten as a famine food and, in some Pacific islands, even a staple food, either raw or cooked.
