Identification. Leaves of A. cuprea are subtended by two marcescent reddish brown cataphylls. The leaf blades are distinctive with bullate between the main veins, adaxially glossy bronze-green but abaxially deep purple. Alocasia cuprea has long been considered as one of the most spectacular and bizarre foliage plants in the genus and is a parent of several interspecific horticultural hybrids ( Hay 1998).

Distribution and ecology. Endemic to Sabah. On slopes in rain forest, over a wide variety of substrates including ultramafics and sandstone, ca. 40–1500 m elev.
