Source: Magness et al. 1971
This bean, known under many names, is a tall viner, up to 20 feet, with broad, ovate leaves. In the U.S., it is cultivated mainly as an ornamental, but in the tropics the pods and seeds are eaten.
The pods are small, 2 to 3 inches long, flat and smooth. Seeds are from 1/4 to 1/2 inch long, nearly as wide, and flattened. Exposure of plant parts is similar to that of pole snap beans. No data are available on U.S. production, but it is insignificant in continental U.S.
