Farm. In moist clayey maize field. MASS COLLECTION: v0239054WIS-v0239074WIS. Aggressively weedy annual, 6 (depauperate)-17 dm tall with 1-6 or more stems from one base. Inflorescences (11-)17-55 cm long to (5-)10-42 cm wide, now beginning to shed the black seeds, though many yet green and not quite out of sheath yet, the former heavy with seed and nodding, the latter, esp. in smaller infls. erect and stiffer. (Species, according to Dr. R. G. Harvey, U.W. Agronomist, a bad weed on many farms in Southern Wisconsin, present here for ca. 8 years (!!?), this doubtful, as this is the first collection from state.)
