Stems without hairs. First leaves petioled, round, without hairs. Erect at first, then become twining or creeping and branched at the base. Alternate, triangular to heart-shaped with a pointed tip. Basal lobes point inward toward the petiole.
Leaves have a continuous, untoothed margin.
Ocrea at base of each petiole, triangular leaves with basal lobes that point inward. Additionally, the ocrea present in wild buckwheat and not in field bindweed is a distinguishing characteristic.
