|discussion=<p>Most records of <i>Rumex longifolius</i> from the Great Plains (Great Plains Flora Association 1977; R. B. Kaul 1986) refer to <i>R. pseudonatronatus</i> (J. E. Dawson 1979), which can be distinguished from <i>R. longifolius</i> by its narrower leaves, smaller and more distinctly triangular inner tepals, and purplish or reddish brown stems at maturity. The two species are closely related; they were placed by K. H. Rechinger (1949) in subsect. Longifolii Rechinger f.</p>
