Alocasia brisbanensis, commonly known as cunjevoi or spoon lily, is a species of plant in the family Araceae native to rainforests of eastern Australia. The common name "cunjevoi" derives from the Bundjalung language of northern New South Wales.
Alocasia brisbanensis has very large, spade-shaped leaves on long, fleshy petioles, and grows to a height of . The perfumed, summer flowers are greenish-cream in colour, and similar to an arum lily. Red fruits follow the flowering.
The plant is poisonous, and contact with the sap can lead to skin and eye irritation due to the presence of needle-like crystals of Calcium oxalate. Eating any part of the plant causes immediate pain, a burning sensation and swelling of the lips, tongue and mouth. A small number of children have died as a result of eating parts of the plant.
