The umbrella. Grows in swampy and wet areas of the islands. The tree is of a tuber nature. I keep thinking of giant white carrots. A basic foodstuff in my grandparents days, when imported rice and flour were difficult to come by. Nowadays the islanders don't favour this tree much... for some reason. About the umbrella? I have seen people using this leaf during thunder showers, a few times..., but almost always in urgent cases.
