Best Life Stage for Proper Identification [-]
Plants with mature fruits are necessary for identification.

Similar Species [-]
R. persicarioides occupies similar habitats to R. fueginus and was historically known from New York, though there are no known extant records.The valves enclosing the achenes of Rumex persicarioides have much shorter (0.5-1.5 millimeters) wings, about as long as the width of the inner tepals, and the tubercle covering the achene is broad, rounded, and straw- colored. In contrast R. fueginus has valves with wings 1.5 to 2.5 times as long as the width of the inner tepals, and brown or reddish, narrow, lanceolate tubercles.
