--><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, usually producing axillary shoots below 1st-order inflorescence or at proximal nodes, (30–)40–100 cm. <b>Leaf</b> blades light or yellowish green, veins scarcely prominent abaxially, linear-lanceolate, 6–17 × 1–4(–5) cm, usually ca. 5–6 times as long as wide, widest near middle, thin, not coriaceous, base cuneate, margins entire, flat or 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, broadly to narrowly paniculate (branches usually with 2d-order branches, rarely simple). <b>Pedicels</b> articulated in proximal 1/3 or almost near base, filiform (but slightly thickened distally), 4–8 mm, usually ca. 1.5 times as long as inner tepals, articulation indistinctly swollen. <b>Flowers</b> 10–25 in whorls; inner tepals broadly triangular, (2–)2.5–3.5(–3.8) × (2–)2.5–3(–3.5) mm, base truncate or rounded, margins entire or indistinctly erose only near base, apex acute, occasionally subobtuse-triangular; tubercles usually 3, (1 in some forms, then large, occupying at least 0.5 width of inner tepal), equal or subequal, much narrower than inner tepals glabrous or minutely verrucose. <b>Achenes</b> brown or dark reddish brown, 1.7–2.2 × 1–1.5 mm. <b>2n</b> = 20.</span><!--

|discussion=<p><i>Rumex triangulivalvis</i> is the most common and widespread species of the <i>R. salicifolius</i> group. It often occurs in ruderal habitats and may be expected outside its present range.</p><!--
--><p>The names <i>Rumex salicifolius</i> and <i>R. mexicanus</i> (in the broad sense) were commonly applied to this species by many North American and European authors.</p>
