Alocasia macrorrhizos is a species of flowering plant in the arum family (Araceae) that it is native to rainforests of Maritime Southeast Asia, New Guinea, and Queensland and has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics. Common names include giant taro, giant alocasia, ʻape, biga, and pia. In Australia it is known as the cunjevoi (a term which also refers to a marine animal).
