It is endemic to the islands of Luzon, Mindanao, and Polillo in the Philippines.

The leaves, like its specific name implies, are highly variable in shape, even in one individual.

Both A. ramosii and A. boyceana are also always non-peltate, while A. heterophylla can sometimes have peltate leaves in mature specimens.

[2] Alocasia heterophylla are restricted to limestone-rich areas of the islands of Luzon, Mindanao, and Polillo.

They are usually found near beaches at elevations of 29 to 200 metres (95 to 656 ft) above sea level.
