I have a pond weed that I have not been able to identify and it is not shown on the TAMU site. It was probably brought by ducks or geese last year and I thought it was a common pond weed but the flowering structure looks nothing like any I have seen. The stems are thick and the leaves 5-7” long I have included two pictures, one of the plant in the water and one of a detached leaf and flowering structure, which I picked to keep it from going to seed. There is a single leaf per stem with no branching. The pond is in NY. Any idea what this is?
