    Plants moderately pubescent distally, becoming glabrescent at maturity. Stems erect, usually green, moderately branched, rarely nearly simple, 0.5-1.5(-2.5) m. Leaves: petiole shorter than to equaling blade; blade rhombic-ovate, ovate, or elliptic to broadly lanceolate, 5-15(-20) × 2-10 cm, base cuneate, margins entire, apex acute to subobtuse, with mucro. Inflorescences terminal, drooping or nodding, usually red, purple, or white, less commonly green, silvery green, or yellow, usually much-branched at base, leafless at least distally, very large and robust. Bracts narrowly lanceolate to linear, equaling or subequal to tepals, not exceeding style branches, apex acuminate with excurrent midrib. Pistillate flowers: tepals 5, spatulate-obovate or lanceolate-obovate, not clawed, subequal, (1-)1.5-2(-2.5) mm, membranaceous, apex obtuse, slightly emarginate, or subacute with mucro; style branches spreading or reflexed; stigmas 3. Staminate flowers mostly at tips of inflorescences; tepals (4-)5; stamens 5. Utricles broadly ovoid to subglobose, 1.5-2(-2.5) mm, ± equaling tepals, dehiscence regularly circumscissile. Seeds dark brown to brownish black or reddish brown, yellowish white, or ivory, lenticular to subglobose, 1-1.2(-1.5) mm diam., smooth or indistinctly punctate.

    "Cult. ornamental and grain-amaranth, apparently derived from the S. Amer. A. quitensis Kunth; monoecious, stout, erect, to 2 m; lvs long-petioled, elliptic to rhombic-ovate, to 2 dm; infl large and showy, generally bright red in life, composed of several to many drooping, spike-like thyrses, the terminal one 1–3 dm, much longer than the lateral; bract of the pistillate fls with slender midrib, not surpassing the fr; sep 5, outcurved above, the inner spatulate and obtuse or emarginate, all over 2 mm and nearly equaling the fr; style-branches slender, spreading from the base; seed most commonly pale ivory, and when fresh flushed with red around the rim, less commonly dark brown; 2n=32, 34. Amer. cultigen, originally cult. for grain, now relictual as a grain-plant, but widely cult. as an ornamental, occasionally escaping or persistent, but scarcely established in our range."

    Annual herb, erect, up to c. 1.5 m in height, commonly reddish or purplish throughout. Stem rather stout, not or sparingly branched, glabrous or thinly furnished with rather long, multicellular hairs which are increasingly numerous upwards. Leaves glabrous, or ± sparingly pilose along the margins and lower surface of the primary venation, long-petiolate (petiole to c. 8 cm but not longer than the lamina), lamina broadly ovate to rhomboid-ovate or ovate-elliptic, 2.5-15 x 1-8 cm, obtuse to subacute at the mucronulate tip, shortly cuneate to attenuate below. Flowers in axillary and terminal spikes formed of increasingly approximated cymose clusters, the terminal inflorescence varying from a single, elongate, tail-like, pendulous spike, to 30 cm or more long and c. 1.5 cm wide, to a panicle with the ultimate spike so formed; male and female flowers intermixed throughout the spikes. Bracts and bracteoles deltoid-ovate, pale-membranous, acuminate and with a long, pale or reddish, rigid, erect arista formed by the yellow-green or reddish stout, excurrent midrib, the longest up to twice as long as the perianth. Perianth segments 5; those of the male flowers oblong-elliptic, 2.5-3.5 mm, acute, aristate; those of the female flowers 1.75-2.5 mm, broadly obovate to spathulate, distinctly imbricate, abruptly narrowed to a blunt or sometimes faintly emarginate, mucronate tip. Stigmas 3, c. 0.75 mm, erect or flexuose. Capsule 2-2.5 mm, ovoid-globose, circumscissile, slightly urceolate, the lid smooth or furrowed below, abruptly narrowed to a short, thick neck. Seeds shining, compressed, black, almost smooth, or commonly subspherical with a thick yellowish margin and a translucent centre, c. 0.75-1.25 mm.
