--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial, glabrous, with vertical rootstock. <b>Stems</b> usually ascending, occasionally erect, usually producing axillary shoots below 1st-order inflorescence, especially at proximal nodes, 15–40(–70) cm. <b>Leaf</b> blades linear-lanceolate or narrowly linear-lanceolate, 6–15 × 1–2(–2.5) mm, usually ca. 6–10 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 occasionally interrupted in proximal 1/2, usually broadly paniculate (branches simple or with few 2d-order branches). <b>Pedicels</b> articulated in proximal 1/3, filiform (but thickened distally), 1.5–3.5(–4) mm, not more than 2–2.5 times as long as inner tepals, articulation indistinctly swollen. <b>Flowers</b> 10–20(–25) in whorls; inner tepals ovate or occasionally ovate-lanceolate, 2.5–3(–3.5) × 1.6–2.5 mm, base broadly cuneate or truncate, margins entire or indistinctly erose, apex obtuse or subacute; tubercles 3, equal or subequal, usually distinctly narrower and much shorter than inner tepals, smooth or weakly rugose. <b>Achenes</b> dark brown, occasionally dark reddish brown, 2–2.5 × 1–1.2 mm. <b>2n</b> = 20.</span><!--

|discussion=<p><i>Rumex</i> hultenii Tzvelev, a species closely related to <i>R. sibiricus</i> (it differs from the latter mostly by inner tepals without tubercles), was reported from Alaska by N. N. Tzvelev (1987b, 1989b). <i>Rumex</i> hultenii is reported to differ from <i>R. utahensis</i> by its narrower leaves, and from <i>R. subarcticus</i> by its smaller inner tepals and erect or ascending (not prostrate) habit, as well as by smaller inner tepals. Records of <i>R. utahensis</i> from Alaska may refer to R. hultenii. I have seen no reliable specimens from North America of R. hultenii and cannot confirm that it occurs in Alaska.</p>
