Leaves nonaromatic; petiole 1-2.5 cm; blade triangular, ovate, or rhombic-ovate, 0.8-4(-8) × 0.4-3(-5) cm, base cuneate to rounded, margins irregularly dentate, apex acute to acuminate, glabrous (rarely indistinctly farinose when young). Inflorescences glomerules in terminal and lateral panicles, 6-7 × 4-5 cm; glomerules subglobose, 2-4 mm diam., or some flowers not in glomerules; bracts absent. Flowers: perianth segments 5, distinct nearly to base; lobes ovate, 0.5-0.8 × 0.6-0.7 mm, apex acute to obtuse, keeled abaxially, farinose, covering fruit at maturity; stamens 5; stigmas 2, 0.2 mm.

Hojas deltoides a rómbicas o rómbico-ovadas, 1–7.7 cm de largo y 0.7–5.1 cm de ancho, obtusas a atenuadas en el ápice, agudas a truncadas en la base, irregularmente dentadas a profundamente serradas, generalmente glabras en la haz, glabras a densamente farinosas en el envés, eglandulares; pecíolo 4–27 (–70) mm de largo. Glomérulos sésiles a lo largo de los raquis ramificados; cáliz de 5 segmentos connados sólo en la base, aquillados, 1–1.3 mm de largo, farinosos, eglandulares; estambres 5, filamentos sobrepasando ligeramente a los lobos del cáliz; estigmas 2 ó 3, subulados, patentes. Utrículo parcialmente envuelto por el cáliz, pericarpo adherido a la semilla; semilla horizontal, 1.3–1.5 mm de largo y 1.2–1.4 mm de ancho, ligeramente tuberculada, opaca, café-rojiza, embrión envolviendo completamente al perisperma.

    Conocida en Nicaragua por una sola colección (Stevens 10105) del basurero de la ciudad de Jinotega; ca 1200 m; fl y fr probablemente todo el año; indígena de Europa, Asia y Africa, ampliamente naturalizada como maleza en América.

    Erect or ascending annuals to as much as 6 dm. tall, the branches ascending, often deeply sulcate, occasionally farinose, especially toward the extremities. Leaves somewhat lustrous and occasionally bullate above, glabrous to rather densely farinose below, deltoid to rhomb-ovate, marginally irregularly and acutely dentate, apically acuminate to attenuate and often mucronate, basally acute to truncate, 2.5-8 cm. long, 2-5 cm. broad, the petioles mostly 3-70 mm. long, sometimes quite as long as the blades. Flowers irregularly disposed in glomerules, the glomerules sessile along the dichotomously branching rhachises, these axillary and terminal, distally farinose. Sepals 5, subequal, ovate, obtuse, cucullate, 1-ribbed, slightly if at all carinate, farinose, basally connate, 1-1.5 mm. long; stamens 5, caducous, the filaments flattened, the anthers orbicular, exserted; ovary subglobose, the style quite short, the 2 (-3) stigmata ca. twice as long, spreading, irregularly glandular. Utricle partially enclosed by the sepals, the seed lenticular-cochleate, minutely tuberculate, dull reddish-brown, 1.2-1.5 mm. broad, horizontal, the pericarp adherent.
