I think this is wild ginger. No flowers that I can see. It's growing amid a pile of water chestnut (Trapa natrans) seed pods on a part of the land that's quite hard to get to. Bladdernut pods are also visible in the second photo. If so, it's yet another plant with elaiosomes whose seeds are distributed by ants that's living on the island.
