The pigeon pea (Cajanus cajan), also known as pigeonpea, red gram, tur,pwa kongo in Haiti,, guandú and frijol de palo in Ibero-America, or as gungo peas in Jamaica, is a perennial legume from the family Fabaceae. Since its domestication in the Indian subcontinent at least 3,500 years ago, its seeds have become a common food in Asia, Africa, and Latin America. It is consumed on a large scale in South Asia and is a major source of protein for the population of the Indian subcontinent. It is the primary accompaniment to rice or roti (flat bread) and has the status of staple diet throughout the length and breadth of India.
