Hygrophila costata

A widespread amphibious marsh plant from the southeastern United States through Central America and the Caribbean to Argentina, sold as an aquarium plant. It grows in mud and shallow water at edges of ditches, ponds and streams in full or partial sun; it is invasive in some countries, so never release it.
