Notes: FNA22: "The sago-pondweed is among the most important species as food for waterfowl (E. Moore 1913). The species reproduces vegetatively by underground tubers and is spread by various duck species, especially canvas backs. In a study of food for ducks, a population of canvas backs was observed feeding in aquatic vegetation comprised of several genera, including sago-pondweed. When the stomach contents were examined, they were found to contain essentially 100% tubers of sago-pondweed (E. Moore 1913).

Two hybrids with this species as a putative parent have been described under the genus Potamogeton. These are P. pectinatus x P. vaginatus (= P. x bottnicus Hagström) and P. filiformis x P. pectinatus (= P. x suecicus K. Richter)."
