High climbing vine, adhering to its support by numerous adhesive disks developing at the ends of the much branched tendrils; lvs long-petioled, the lfls dull green above, paler and slightly glaucous beneath, elliptic to obovate, 6–12 cm, abruptly acuminate, sharply serrate chiefly beyond the middle, cuneate to the base, sessile or on petiolules to 15 mm; infls terminal and from the upper axils, forming panicles usually longer than wide, with a well marked zigzag sympodial axis and divergent branches, the fls in terminal umbelliform clusters; frs nearly black, 6 mm; 2n=40. Moist soil; Me. to O., Io., and Nebr., s. to Fla. and Tex. June. (Psedera q.; P. hirsuta)
