  • Description

    Species Description - Annual, branched from the base, prostrate to erect, 1–8 dm, the foliage and fls commonly tinged with red or becoming red at maturity; lvs commonly rhombic-ovate or oblong, with a conspicuous lateral tooth on each side, cuneate below the teeth, varying to entire or several- toothed, green on both sides; fls in ± numerous glomerules, these to ca 5 mm thick at maturity, in small plants chiefly axillary, in larger ones aggregated into terminal paniculiform infls; sep mostly 3; seeds erect, shiny dark brown, lenticular, 0.6–1 mm wide; 2n=36. Salt marshes and brackish soil, Nf. to N.J.; more abundant inland, from Ind. and Io. to Wash. and Calif., and occasionally adventive elsewhere. Tall, erect plants with lvs 4–10 cm and large infls are typical C. rubrum. Prostrate plants with small lvs and only axillary glomerules have been segregated on insufficient grounds as C. humile Hook. or C. rubrum var. humile (Hook.) S. Wats.
