Leaves not clustered; stipules filiform, 2–5 mm; petiole 0.5–6 cm, glands absent at apex; blade ovate to lanceolate-elliptic, 3–8(–15) × 1–4 cm, base rounded to cuneate, margins entire, apex obtuse to acute or rounded, abaxial surface light green, not appearing brown-dotted, no stellate hairs with brown centers, adaxial surface darker green, both appressed stellate-hairy. Inflorescences bisexual, racemes or capitate, 1.5–3 cm, staminate flowers 5–15, pistillate flowers 3–6. Pedicels: staminate 0.5–1.5 mm, pistillate 0–1.5 mm. Staminate flowers: sepals 5, 0.8–1 mm, abaxial surface stellate-hairy; petals 5, linear-oblong-lanceolate, 0.8–1 mm, abaxial surface stellate-hairy; stamens 7–12. Pistillate flowers: sepals 6–9, equal, 7–10 mm to 15 mm in fruit, opening broadly and persistent after capsule dehiscence, margins entire, apex recurved, abaxial surface stellate-hairy; petals 0; ovary 3-locular; styles 3, 2–3 mm, 2–3 times 2-fid, terminal segments 12–18(–24).

"Annual, to 1 m, sparingly and somewhat umbellately branched above; lvs narrowly triangular to oblong, lanceolate, or ovate-oblong, 4–10 cm, the principal ones with the blade rounded at base and less than twice as long as the petiole; fls in dense terminal infls 1–3 cm; staminate fls with 5 sep, 5 pet, and 10–14 stamens; pistillate fls apetalous, the 6–10 sep accrescent to 1 cm; styles 3, each 2–3 times dichotomous, the stigmas thus 12–24; 2n=20. Dry, usually sandy soil and waste places; O. to Ind. and Neb., s. to Fla. and Tex. Ours are var. capitatus."
