Plants green, heterophyllous (often lacking larger proximal stem leaves at maturity). Stems 1–3, ascending or erect, sometimes decumbent, basal branches divaricate, (10–)25–75(–100) cm. Leaves: ocrea (5.5–)6–10(–14) mm, proximal part cylindric, distal part silvery, hyaline, soon lacerate and disintegrating into fibers; petiole 1–6(–8) mm; blade green, lateral veins visible but not raised abaxially, elliptic to oblanceolate, 18–50(–60) × (6–)10–20 mm, 2–4.5 times as long as wide, apex acute or obtuse; stem leaves 1.4–4 times as long as branch leaves. Cymes aggregated at tips of stems and branches, 3–8-flowered. Pedicels mostly exserted from ocreae, 2–5 mm. Flowers: perianth (2.3–)2.8–4.7(–5) mm, 1.8–2.8 times as long as wide; tube (15–)20–37% of perianth length; tepals overlapping, green with pink, red, or white margins, oblong, flat (cucullate in fruit), outer tepals not pouched at base; veins branched, thickened; stamens 7–8. Achenes enclosed in or barely exserted from perianth, brown to dark brown, ovate, 3-gonous, (2.1–)2.7–3.7 mm, faces subequal, concave, apex straight, striate-tubercled; late-season achenes uncommon, 3.5–5 mm. 2n = 40, 60.
Phenology: Flowering May–Oct.
Habitat: Fields, uncultivated areas, waste places, roadsides
