The pigeon pea 樹豆 (shù dòu) Cajanus cajan is a perennial legume in the Fabaceae family which has been cultivated on the Indian subcontinent for at least 3,500 years ago. The seeds are an important source of protein in Asia, Africa, and Latin America. The bean is also central to many of Taiwan's indigenous peoples. It is called fata'an by the Amis, singut by the Tayal and qalidang by the Bunun.
