Pitted morningglory is a member of the Convolvulaceae or morningglory family. It is an annual climbing or trailing vine that is thought to be native to tropical or subtropical North America. This vine can grow to lengths of 6 feet. Pitted morningglory cotyledons are sharply indented, lack hairs (glabrous), may be green or purplish, and are pointed. Stems are highly branched, smooth to slightly hairy, and vining or climbing. The leaves are alternate and heart-shaped, tapering to a point. The leaves may be slightly hairy or smooth and they are on long petioles. Leaves may have purple margins. Flowers are white, funnel-shaped and close to an inch broad. Pitted morningglory has a taproot system. Fruit is enclosed in a capsule and the seeds are black and somewhat large. The deeply indented cotyledon lobes help distinguish this species from other morningglories. In addition, the white flowers set it apart from tall morningglory, which typically has large, showy, purple flowers.
