The winged bean (Psophocarpus tetragonolobus), also known as the Goa bean, four-angled bean, four-cornered bean, Manila bean, Mauritius bean, Dragon bean, is a tropical legume plant native to New Guinea.
It grows abundantly in the hot, humid equatorial countries of South and Southeast Asia. In Southeast Asia and Papua New Guinea it is widely known, but only cultivated on a small scale. Winged bean is widely recognised by farmers and consumers in southern Asia for its variety of uses and disease resistance. Winged bean is nutrient-rich, and all parts of the plant are edible. Leaves can be eaten like spinach, flowers can be used in salads, tubers can be eaten raw or cooked, seeds can be used in similar ways as the soybean. The winged bean is an underutilised species but has the potential to become a major multi-use food crop in the tropics of Asia, Africa, and Latin America.
The winged bean species belongs to the genus Psophocarpus, which is part of the legume family, Fabaceae. Species in the Psophocarpus genus are perennial herbs grown as annuals.Psophocarpus species have tuberous roots and pods with wings. They can climb by twining their stems around a support.
The winged bean plant grows as a vine with climbing stems and leaves, 3–4 m in height. It is an herbaceous perennial, but can be grown as an annual. It is generally taller and notably larger than the Common bean. The bean pod is typically 15–22 cm (6–8.5 in) long and has four wings with frilly edges running lengthwise. The skin is waxy and the flesh partially translucent in the young pods. When the pod is fully ripe, it turns an ash-brown color and splits open to release the seeds. The large flower is a pale blue. The beans themselves are similar to soybeans in both use and nutritional content (being 29.8% to 39% protein).
