|discussion=<p>The name <i>Rumex graminifolius</i> was commonly misapplied to this species in northwestern North America and northeastern Eurasia.</p><!--
--><p><i>Rumex krausei</i> is closely related to <i>R. beringensis</i> and probably represents the latter’s triploid race. <i>Rumex krausei</i> differs from <i>R. beringensis</i> in having larger flowers, fruiting inner tepals, and fruits, and shorter and less-branched or unbranched inflorescences. <i>Rumex krausei</i> occurs in eastern Chukotka, Russia, together with <i>R. beringensis</i>; however, it is believed to be confined mostly to clay soils and limestones. It has been reported from the Ogotoruk River on the northwestern coast of Alaska (B. A. Jurtzev et al. 1975) and some other Alaskan regions (western Seward Peninsula, capes Dyer and Thompson, and the Squirrel River). It may be expected anywhere within the range of <i>R. beringensis</i>.</p><!--
