Annual, sometimes bushy herb to  c. 75 cm tall, glabrous except for farina, non-aromatic, often tinged dark red.  Stems strongly ascending to erect, rarely decumbent, branched, ridged.  Lvs very variable in size, generally with petiole 1–2× lamina;  lamina mostly 1–7–(12.5) × 0.5–6–(8) cm, rhombic-ovate, broad-triangular, sometimes farinose, usually dark green, but often distinctly reddish purple where exposed, never glaucous, coarsely and irregularly dentate-serrate;  base narrow- to broad-cuneate;  apex usually acute, sometimes obtuse;  upper infl. lvs smaller and narrower, less deeply toothed.  Infls paniculate, much-branched, terminal and axillary;  branches to nearly 5 cm long, leafy nearly to apex, ± farinose;  fls in rather densely crowded glomerules, farinose.  Perianth segments  c. 1 mm long, imbricate, bluntly keeled on back, green or reddish purple;  margins hyaline.  Fr. surrounded by perianth except near apex;  pericarp tightly adherent.  Seed horizontal, 1.1–1.5 mm diam., flattened vertically, orbicular;  margin acute;  testa black, minutely pitted.
