--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>not developing basal rosette of leaves, sometimes with long-creeping rhizomes. <b>Stems</b> erect, ascending, procumbent, or decumbent, normally with regular, leafy axillary shoots that tend to develop 2d-order axillary inflorescences (often overtopping 1st-order ones). <b>Leaf</b> blades mostly lanceolate, elliptic, ovate-lanceolate, or ovate-elliptic, base cuneate, or in some species broadly cuneate, rounded, truncate-cuneate, or indistinctly cordate. <b>Inner</b> tepals with margins entire, rarely minutely erose-denticulate.</span><!--

--><p>North american representatives of this section (except <i>Rumex venosus</i>, a distinctive species) form a polymorphic complex consisting of often interfertile races (N. M. Sarkar 1958). In most cases those races are separated morphologically and restricted geographically. They may be arranged into at least three aggregates (groups) that approximate the subsections described by K. H. Rechinger (1937): <i>R. verticillatus</i> aggr. (subsect. Verticillati Rechinger f.), <i>R. altissimus</i> aggr. (subsect. Salicifolii Rechinger f., in part), and <i>R. salicifolius</i> aggr. (subsect. Salicifolii, in part). In case of difficulty with identification, inevitable with immature or intermediate specimens, determination to the aggregate level is recommended. Those preferring more broadly circumscribed species may use existing infrageneric combinations (see J. C. Hickman 1984). Attempts have been made to submerge various “microspecies” (especially in the <i>R. salicifolius</i> group) into more broadly circumscribed taxa, usually <i>R. salicifolius</i> and <i>R. mexicanus</i>, and various combinations at subspecific and varietal ranks have been proposed (see Hickman). In my opinion, results of this approach are inconsistent (e.g., some taxa are treated as varieties while others, not less distinct, are accepted as species or subspecies) and in most cases less convincing than the original treatment by Rechinger and the thorough study by Sarkar. I agree with Sarkar (p. 993) that “any drastic taxonomic revision of the species of the Axillares section of <i>Rumex</i> should be postponed until more complete cytogenetic data have accumulated concerning the interrelationships of all the taxa in this section.”</p>
