Vigna aconitifolia

Vigna aconitifolia is a drought-resistant legume, commonly grown in arid and semi-arid regions of India. It is commonly called mat bean, moth bean, matki or dew bean.

Moth bean is a creeping annual herbaceous plant which grows to approximately 40 centimetres (16 in) high. Yellow flowers on its hairy and densely packed branches develop into yellow-brown pods, 2 to 3 inches in length. The beans of these pods contain approximately 22–24% protein.

The pods, sprouts, and protein-rich seeds of this crop are commonly consumed in India. Moth bean can be grown on many soil types, and can also act as a pasture legume. Due to its drought-resistant qualities, its ability to combat soil erosion and its high protein content, moth bean has been identified as possibly a more significant food source in the future. It has been suggested that its suitability as a grain legume in semi-arid Africa should be further investigated.
