Stuckenia striata is widespread, although not common, in the western United States, extending southward into Argentina and Chile. Potamogeton latifolius [no combination in Stuckenia has been proposed] was accepted by R. F. Thorne (1993b). After examining specimens throughout the range and studying dozens of populations in the field, we have determined that the two names represent the same taxon. We are placing P. latifolius in synonymy.
