Other Common Names: honeyvine, climbing milkweed, sandvine

Synonyms: Cynanchum laeve, Ampelamus laevis, Gonolobus laevis

Leaves: Opposite, entire, heart-shaped, 3-7 inches long, 1.5-5 inches wide. Leaves do not have hairs and occur on petioles that are 1-4 inches long. Leaf surfaces have conspicuous white veins that arise from a common point (palmate venation).

Identifying Characteristics: A perennial with slender, twining stems that may reach 10 ft in length. Found throughout the southeastern United States. Although the name implies a secretion of milky sap as in other milkweed species (Asclepias spp.), this does not occur in the leaves or stems of honeyvine milkweed. A perennial twining vine with opposite leaves and relatively large fruit (follicle). This weed is often incorrectly identified as a morningglory (Ipomoea spp.) or Field Bindweed (<a href='../../weedimg/79'>Convolvulus arvensis</a>). However, the prominent white veins distinguishes this weed from any of the morningglories, and the heart-shaped leaf distinguishes this weed from field bindweed

Seed Fruit: A smooth, angled follicle that is 3.5-5.5 inches long, 1-2.5 inches wide.
