Alocasia macrorrhizos

Alocasia macrorrhizos is a species of flowering plant in the arum family (Araceae) that is native to rainforests of Maritime Southeast Asia, New Guinea, and the Murray Islands group in the Torres Strait. It has long been cultivated in South Asia, the Philippines, many Pacific islands, and elsewhere in the tropics, in the order of tens of thousands of years. 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).
