--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, glabrous, with vertical rootstock, occasionally with short-creeping rhizomes. <b>Stems</b> ascending or erect occasionally almost procumbent, usually producing axillary shoots below 1st-order inflorescence or at proximal nodes, 30–60(–80) cm. <b>Leaf</b> blades linear-lanceolate, 10–20(–22) × 1–3.5(–4.5) mm, usually ca. 7–10 times as long as wide, widest near middle, thick, coriaceous, base cuneate, margins entire, flat or slightly undulate, apex acute. <b>Inflorescences</b> terminal and axillary, terminal usually occupying distal 1/5–1/3 of stem, rather dense or interrupted in proximal 1/2, usually broadly paniculate (distal branches simple, proximal ones usually with few 2d-order branches). <b>Pedicels</b> articulated in proximal 1/3 or almost near base, filiform, 4–6 mm, not more than 2–2.5 times as long as inner tepals, articulation indistinctly swollen. <b>Flowers</b> 10–20 in whorls; inner tepals, broadly ovate-triangular or almost deltoid, occasionally broadly triangular, (2.5–)3–4 × 2–3.5 mm, base truncate or round, occasionally indistinctly cordate, margins entire or indistinctly erose, apex obtuse or subacute; tubercles 3, equal or subequal, all tubercles, or at least largest tubercle pale, subequal to inner tepals or slightly narrower than inner tepals, often minutely verrucose. <b>Achenes</b> brown or dark reddish brown, 2–3 × 1–1.5 mm. <b>2n</b> = 20.</span><!--

|discussion=<p><i>Rumex pallidus</i> is restricted to northeastern North America. Specimens with more “strict habit, larger leaves, and more erect fruiting branches” reported by K. H. Rechinger (1937) from Alaska and Yukon as this species belong instead to <i>R. sibiricus</i> (E. Hultén 1941–1950, vol. 4). Those species, as well as <i>R. subarcticus</i> and R. hultenii Tzvelev, represent a rather natural northern group of the <i>R. salicifolius</i> aggregate. The hybrid <i>R. pallidus</i> × <i>R. triangulivalvis</i> was reported from the western part of New York (R. S. Mitchell 1986).</p>
