--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, glabrous or slightly papillose-pubescent especially on leaf blades abaxially, with long-creeping rhizomes and/or stolons. <b>Stems</b> and axillary shoots ascending or erect, branching in distal 2/3, (5–)10–30(–40) cm. <b>Leaf</b> blades distinctly obovate or obovate-elliptic, 5–8(–12) × (2–)3–5(–7) cm, widest in distal 1/2, rather fleshy, coriaceous, base cuneate, margins entire to obscurely repand, crisped or occasionally flat, apex obtuse, rounded. <b>Inflorescences</b> terminal and axillary, occupying distal 1/2–2/3 of shoots, usually dense at least in distal part, narrowly to broadly paniculate (but branches in most cases simple or nearly so). <b>Pedicels</b> articulated near middle or in proximal 1/3, thickened (especially distally), 3–5 mm, not more than 2–2.5 times as long as inner tepals, articulation distinct, swollen. <b>Flowers</b> 5–20 in whorls; inner tepals ovate-deltoid or ovate-triangular, 4–5 × (2.5–)3–3.5 mm, base broadly cuneate or truncate, margins entire, apex obtuse or subacute; tubercles 3, equal or unequal, finely punctate. <b>Achenes</b> glossy brown or dark reddish brown, 2.5–3 × 1.8–2.5 mm. <b>2n</b> = 40.</span><!--

|discussion=<p><i>Rumex cuneifolius</i>, a representative of the predominantly South American subsection Cuneifolii Rechinger f., is an uncommon alien known from a few localities in North America. It may have become naturalized in the southwestern part of the United States, especially in coastal regions. The species is known definitely from Portland, Oregon, and was reported as “apparently well established in s.c. Oregon” (C. L. Hitchcock et al. 1955–1969, vol. 2).</p><!--
--><p>This species may have been reported from Provo, Utah, by Á. Löve (1986), as <i>Rumex</i> frutescens. However, it is not mentioned by S. L.Welsh et al. (1993).</p><!--
--><p>The name <i>Rumex</i> frutescens Thouars has been misapplied to <i>R. cuneifolius</i> in both Europe and North America. According to K. H. Rechinger (1990), R. frutescens in the narrow sense is an endemic species of the remote South Atlantic islands Tristan de Cuhna and Gough; it differs from <i>R. cuneifolius</i> in having thinner rhizomes, shorter petioles and leaf blades, and smaller inner tepals. <i>Rumex cuneifolius</i> can hybridize with some other species (J. E. Lousley 1953).</p>
