Taro (Colocasia esculenta), tannia (Xanthosoma violaceum), giant taro (Alocasia macrorrhizos), giant swamp taro (Cyrtosperma chammissonis) and elephant foot yam (Amorphophallus paeoniifolius) have been shown to contain varying amounts of cyanide in their leaves and stems. The amounts of cyanide in Xanthosoma and Colocasia are only about 1-5% of that found in cassava leaves and tubers, and are not a cause for concern for human nutrition. There are much larger amounts present in giant taro, eaten in Java and Tonga, but consumption of leaves is not common.
