This climbing vine occurs in open woods and roadsides, and twines other plants with long petioles. Leaves are ovate to oblong, often divide into 3-5 lobes deeply at underneath of the stem. They look like tomato's leaves. From August to September, sparsely cymes of small whitish flowers are seen on terminal stems or axils.
