--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>annual, pubescent in distal parts or becoming glabrescent at maturity. <b>Stems</b> erect to ascending or decumbent, branched at or distal to base, 0.1–0.9 m. <b>Leaves</b>: petiole variable in length; blade lanceolate to nearly linear or rhombic-ovate to elliptic-ovate, (1.5–)2–4(–5) × 1–3 cm, base cuneate to broadly cuneate, margins entire, plane, rarely indistinctly undulate, apex subacute to obtuse or emarginate, mucronulate. <b>Inflorescences</b> axillary glomerules, green. <b>Bracts</b> lanceolate, subspinescent, 1.5–2 mm, shorter or slightly longer than tepals. <b>Pistillate</b> flowers: tepals 3, erect, elliptic to lanceolate-elliptic, equal or subequal, 1.5–2 mm, apex short-acuminate; style branches slightly spreading; stigmas (2–)3. <b>Staminate</b> flowers intermixed with pistillate; tepals 3, equal or subequal; stamens 3. <b>Utricles</b> subglobose to broadly elliptic, 2–2.5 mm, slightly rugose, dehiscence regularly circumscissile, rarely irregularly dehiscent. <b>Seeds</b> black, lenticular, 1–1.3(–1.6) mm diam., smooth or indistinctly punctate.</span><!--

|discussion=<p>In North America the name <i>Amaranthus graecizans</i> has been constantly misapplied to the common North American taxa <i>A. albus</i> and <i>A. blitoides</i>. Consequently, <i>A. graecizans</i> has been excluded from lists of North American plants. Recently, herbarium specimens (casual aliens collected in 1879 on ballast in Camden, New Jersey) of <i>A. graecizans</i> subsp. sylvestris were discovered (M. Costea et al. 2001b). Probably, the species disappeared in North America long ago, but, considering the long history of misidentification and confusion, there is also some chance that it may occur locally as an introduced species.</p><!--
--><p>Three subspecies are usually recognized within <i>Amaranthus graecizans</i> in the Old World: subsp. graecizans, subsp. sylvestris (Villars) Brenan, and subsp. thellungianus (Nevski) Gusev. Only subsp. sylvestris, characterized by rhombic-ovate to elliptic-ovate leaves (as compared to lanceolate to almost linear leaves in subsp. graecizans) and comparatively large seeds has so far been reported from North America.</p><!--
--><p>Despite its superficial similarity to <i>Amaranthus albus</i> and <i>A. blitoides</i>, <i>A. graecizans</i> seems to be more closely related to other Old World taxa with trimerous flowers.</p>
