Ecology : Cultivated extensively in tropical Africa at 400-2400 m alt. in wet places for its starch-rich tubers ground to give a kind of flour, taro. Frequently naturalized near streams, on river banks or waterfalls. In Togo a member of the Marantochloo purpureae-Anubiadetum giganteae association (Acta Bot. Gall. 158: 413, 2011).
