Colocasia esculenta
A survey of the pits that have previously been used to grow Swamp taro ("Cyrtosperma chamissonis"), (known in Tuvalu as "Pulaka") established that the pits were either too saline or very marginal for swamp taro production, even though a more salt-tolerant species of taro ("Colocasia esculenta") is grown on Fongafale.
