This member of the Araceae family was given this name by Heinrich Wilhelm Schott in 1832. It is found in Bismarck Archipelago, Borneo, Maluku, New Guinea, Philippines, Queensland; AU, Solomon Island and  Sulawesi; Indonesia, growing in a rich but well drained soil with lots of water and fertilizer. It doesn't need much sun, but can stand some. The rhizomes will get 20 centimetres in diameter, the stem will reach for up to two meters or more. The flowers are white to crème, and the plants can be reproduced both by seeds, offsets, cuttings of the rhizomes and stems.

The genera name is an anagram of Colocasia, which it resembles. The species name means 'big-rooted'.
