Herbs annual, to 1 m tall. Stem erect, usually stout, terete, ribbed, green striate, subglabrous; branches cylindric, obliquely spreading. Leaves alternate or subopposite; petiole 1-3 cm; leaf blade triangular-hastate, 5-10 × 4-10 cm, abaxially slightly furfuraceous, adaxially glabrous, base slightly cordate or subtruncate, margin irregularly serrate or with 1-3 pairs of unequal, serrate lobes below middle, apex acute or acuminate. Inflorescences spikelike or paniculate on upper part of stem and branches. Male flower: perianth yellow, subglobose, 5-parted; stamens 5. Fruiting bracts connate only at base, rhombic to ovate-triangular, densely furfuraceous, margins usually entire. Utricle ca. 1.2 mm; pericarp yellow-white, adnate to seed. Seed black, sublustrous, compressed globose. Fl. Jul-Aug, fr. Sep-Oct.

Herbs, monoecious, erect, decumbent or procumbent, branching, 1-10 dm; stems subangular to angular, green or striped. Leaves opposite or subopposite at least proximally; petiole (0-)1-3(-4) cm; blade triangular-hastate, lobes spreading, 20-100 mm and almost as wide, base truncate or subcordate, margin entire, serrate, dentate, or irregularly toothed, apex acute to obtuse. Flowers in spiciform naked spikes 2-9 cm, sometimes forming terminal panicles; glomerules tight, contiguous or irregularly spaced. Fruiting bracteoles green, becoming brown to black at maturity, triangular-hastate to triangular-ovate, veined or veins obscure, 3-5 mm, thin to thickened, spongy, base truncate to obtuse, margin united at base, lateral angles mostly entire, apex acute, faces smooth or with 2 tubercles. Seeds dimorphic: brown, flattened, disc-shaped, 1-2.5 mm wide, or black, 1-1.5 mm wide; radicle subbasal, obliquely antrorse to spreading. 2n = 18.
