--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, glabrous or very indistinctly papillose normally only on veins of leaf blades abaxially, with fusiform, vertical rootstock. <b>Stems</b> erect, branched distal to middle, 40–80(–130) cm. <b>Leaves</b>: ocreae usually deciduous, rarely partially persistent at maturity; blade oblong-lanceolate, lanceolate, or narrowly lanceolate, normally 15–25(–30) × 2–7 cm, base cuneate or truncate, margins entire or irregularly denticulate, usually crisped and undulate, or, occasionally, flat, apex acute or subobtuse. <b>Inflorescences</b> terminal, occupying distal 1/2 of stem, dense or interrupted at base, narrowly paniculate, branches usually straight or occasionally arcuate. <b>Pedicels</b> articulated in proximal 1/3, filiform, 3–8 mm, articulation distinctly swollen. <b>Flowers</b> 20–25 in whorls; inner tepals orbiculate-ovate or occasionally ovate-deltoid, 3.5–5 × 3–5 mm, base truncate or slightly cordate, margins denticulate, apex acute or subacute, teeth 4–10 at each side, 0.2–1.5 mm; tubercles normally 3, equal or subequal, less than 2 times as wide as inner tepals. <b>Achenes</b> usually reddish brown or dark brown, 2–2.5(–3) × 1–1.5 mm. <b>2n</b> = 60.</span><!--

|discussion=<p>Within its native range <i>Rumex stenophyllus</i> is mostly confined to slightly saline coastal and alluvial (riparian) habitats. It has successfully colonized a wide range of ruderal and segetal habitats in both Europe and North America. Further spread of this species in the central and southwestern United States and southern Canada may be expected (D. Löve and J.-P. Bernard 1958). It was placed by K. H. Rechinger (1949) in subsect. Stenophylli Rechinger f.</p><!--
--><p>According to J. K. Morton and J. M. Venn (1990), reports of <i>Rumex stenophyllus</i> from Ontario refer to the hybrid <i>R. crispus</i> × <i>R. obtusifolius</i>, but <i>R. stenophyllus</i> may be found in the province in the future. <i>Rumex stenophyllus</i> may be distinguished from that hybrid by its fertile fruits and more uniform inner tepals.</p>
