--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, glabrous or nearly so, with short and relatively thin, horizontal or slightly oblique rootstock (usually not reaching deep into substrate) and ± crowded 2d-order roots. <b>Stems</b> erect or rarely ascending, 1 to several from base, branched in distal 1/2 (in inflorescence), (25–)30–90(–110) cm. <b>Leaves</b>: ocrea normally laciniate; blade oblong-ovate, ovate-lanceolate, to lanceolate, 4–10(–15) × 1–4(–6) cm, normally more than 2.5 times as long as wide, base sagittate (with acute lobes directed downward, ± parallel to petiole), margins entire, normally flat, apex acute or subacute. <b>Inflorescences</b> terminal, occupying distal 1/3 of stem, usually lax and interrupted especially in proximal part, narrowly paniculate, cylindric (with 1st-order branches simple, or with few 2d-order branches). <b>Pedicels</b> articulated near middle, filiform, 2–5(–6) mm, articulation distinct. <b>Flowers</b> (2–)4–8(–10) in whorls; inner tepals orbiculate, occasionally broadly ovate, 3–4(–5) × 3–4 mm, base rounded or cordate, apex obtuse; tubercles small or occasionally absent. <b>Achenes</b> black to dark brown, 1.8–2.5 × 1.2–1.5 mm, shiny, smooth. <b>2n</b> = 14 (pistillate plants), 15 (staminate plants).</span><!--

|discussion=<p><i>Rumex acetosa</i> is morphologically uniform in North America. It sometimes is misidentified as <i>R. hastatulus</i> orR. acetosella. Collections from North America are few in herbaria, and this species probably is not as common in the flora area as has been generally assumed. Some literature reports for <i>R. acetosa</i> may refer to other taxa of the species group.</p>
