Solanum mammosum is commonly known as nipplefruit, titty fruit, cow's udder, or, ambiguously, "Apple of Sodom". It is an annual or tender perennial plant in the Solanaceae family, part of the Solanum or nightshade genus, and a relative of the tomato and potato. This poisonous fruit is native to South America, but has been naturalized in the Greater Antilles, Central America and Caribbean.
