Rumex hultenii Tzvelev, a species closely related to R. sibiricus (it differs from the latter mostly by inner tepals without tubercles), was reported from Alaska by N. N. Tzvelev (1987b, 1989b). Rumex hultenii is reported to differ from R. utahensis by its narrower leaves, and from R. subarcticus by its smaller inner tepals and erect or ascending (not prostrate) habit, as well as by smaller inner tepals. Records of R. utahensis 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.

Inflorescences terminal and axillary, terminal usually occupying distal 1/ 1/ 3 of stem, rather dense or occasionally interrupted in proximal 1/ 2, usually broadly paniculate (branches simple or with few 2d-order branches). Pedicels articulated in proximal 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. Flowers 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.
