The following images are from specimens found growing on moist soil...not in water. They would "key" most closely to the variety porteri but likely represent a form of var. diffusa (form taken when var. diffusa grows on soil...not in water???). The leaves are less dissected than those of typical variety diffusa, are laminate and the achenes little compressed.
