--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual or short-lived perennial, glabrous, with vertical rootstock. <b>Stems</b> solitary or several from base, erect or ascending, branched in distal 2/3 (in inflorescence), 10–40(–45) cm. <b>Leaves</b>: blade obovate-oblong, ovate-lanceolate, oblong-lanceolate, or lanceolate; 2–6(–10) × 0.5–2 cm, base hastate (with spreading lobes), auriculate, or occasionally without evident lobes, margins entire, flat, apex obtuse or subacute. <b>Inflorescences</b> terminal, occupying distal 2/3 of stem, usually lax and interrupted, narrowly paniculate. <b>Pedicels</b> articulated in proximal part, filiform, 1.5–2.5(–3) mm, articulation indistinct or slightly swollen. <b>Flowers</b> 3–6(–8) in whorls; inner tepals orbiculate or broadly ovate, 2.5–3.2 × 2.7–3.2 mm, base broadly cordate or rounded, apex obtuse or subacute; tubercles absent or some inner tepals with slightly swollen central veins. <b>Achenes</b> brown or dark brown, 0.9–1.2 × 0.6–0.8 mm. <b>2n</b> = 8 (pistillate plants), 9 (staminate plants), 10 (both sexes).</span><!--

|discussion=<p><i>Rumex hastatulus</i> is distinct in subg. Acetosa and belongs to the monotypic subsect. Americanae Á. Löve & N. Sarkar. It is represented by at least two chromosome races: populations occurring from North Carolina to Florida and Mississippi normally have 2n = 8 in pistillate plants and 2n = 9 in staminate plants; populations from Louisiana to Texas and Oklahoma predominantly have 2n = 10 in both sexes. <i>Rumex hastatulus</i> has been reported from New Mexico (W. C. Martin and C. R. Hutchins 1980, vol. 1), but those records need confirmation. When fruiting, <i>R. hastatulus</i> has large inner tepals that distinguish it from <i>R. acetosella</i>, with which it is occasionally confused.</p>
