Millsp., syn. Cajanus indicus) is a member of the Fabaceae family and has many wild relatives. These include Cajanus scarabaeoides (L.) Thouars, C. sericeus (Benth. ex Baker) Maesen, C. acutifolius (F. Muell.) Maesen, C. albicans (Wight & Arn.) Maesen, Rhynchosia aurea, R. bracteata Benth. ex Bak and Flemingia bracteata (Roxb.) Wight (van der Maesen 1985). The pigeonpea plant is an erect annual or short-lived perennial reaching a height of 1–3 m. Because the coarse bush is deeply rooted, it has wide adaptability and grows well in semi-arid areas. It has slender, pointed trifoliate leaves and yellow or yellow and red flowers. Pods are green and pointed with some reddish mottling. Several pods are produced in clusters on an upright stem. %Z These guidelines have been peer reviewed by Kameswara Rao, International Center for Biosaline Agriculture (ICBA), Dubai, UAE.
