Psophocarpus tetragonolobus

The winged bean (Psophocarpus tetragonolobus), also known as cigarillas, Goa bean, four-angled bean, four-cornered bean, manila bean, princess bean, star bean, kamrangi bean, pea, or dragon bean, is a tropical herbaceous legume plant. Winged bean is widely recognised by consumers and farmers in South Asia and South East Asia for its variety of uses and disease resistance. Winged bean is nutrient-rich and all parts of the plant are edible. The leaves can be eaten like spinach, flowers can be used in salads, tubers can be eaten raw or cooked, and 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....read more on Wikipedia.
