--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>short-lived perennial or annual, pubescent in distal parts of plant or becoming glabrescent at maturity. <b>Stems</b> ascending or prostrate, profusely branched basally, radiating from rootstock, mostly 0.2–0.5 m. <b>Leaves</b>: petiole 1/2 as long as to equaling blade; blade rhombic-ovate or ovate to lanceolate, 1–2 × 0.5–1 cm, base tapering or cuneate, margins entire, plane or slightly undulate, apex subacute, obtuse, or retuse or shallowly emarginate, mucronulate. <b>Inflorescences</b> terminal, erect, compact, pyramidal panicles and also some axillary clusters, green or silvery green, occasionally tinged with red, leafless at least distally. <b>Bracts</b> of pistillate flowers linear, 0.5–1 mm, 1/2 as long as tepals. <b>Pistillate</b> flowers: tepals 2–3, narrowly elliptic or oblanceolate, not clawed, equal or subequal, 1.2–2 mm, apex broadly acute; style branches erect; stigmas 3. <b>Staminate</b> flowers clustered at tips of inflorescences; tepals 2–3; stamens 2–3. <b>Utricles</b> marked with 2(–3) green lines that intersect at apex and divide fruit into halves or quarters, slightly to distinctly inflated, ellipsoid, 2–3 mm, distinctly longer than tepals, smooth (in dry plants wrinkled or rugose), indehiscent. <b>Seeds</b> very dark brown to black, 1–1.2 mm diam., shiny, filling only proximal portion of fruit.</span><!--

|discussion=<p>The hybrid between <i>Amaranthus deflexus</i> and <i>A. muricatus</i> was described from Europe as A. ×tarraconensis Sennen & Pau (see J. L. Carretero 1979) and may be expected in North America in the future in places of possible co-occurrence of the parental species.</p>
