If you find a tuber called coco-yam that would be Xanthsoma a very very large cousin of the Colocasia esculenta. I had someone send me what they thought was Xanthsoma, but it was actually an Colocasia. The leaf structure is different as the two back sections in Xanthosma are not connected (saggitate) where as the Colocasia's aren't. Was sad that it wasn't a Xanthsoma
