It looks like arrow arum (Peltandra virginica), but may be a related
species. Good shallow water plant (U.S. native) that can tolerate a
lot of shade. It produces a spathe flower, similar to that of calla
lilies. The bulb like thingy is the fruit, which contains large seeds
and somewhat resembles a short ear of corn when peeled back (hence a
second common name, duck corn).
