Wild Buckwheat is an annual twining or trailing vine that may reach as much as 3 1/2 feet in length. Wild buckwheat is found throughout the United States. The cotyledons are linear, approximately 20 mm long and 3 mm wide, without hairs. Stems are without hairs. First leaves occur on petioles and are without hairs. Wild Buckwheat's stems are erect at first, then become twining or creeping and branched at the base. A membranous sheath (ocrea) surrounds the stem at the base of each leaf petiole. Flowers are clustered in racemes from the leaf axils (the position between the stem and a leaf), are inconspicuous and greenish-white in color. Leaves are alternate, triangular to heart-shaped with a pointed tip. Basal lobes point inward toward the petiole. Leaves have a continuous, untoothed margin.
