Groundnut-or peanut as it is also called-is a four-foliate legume with yellow sessile flowers and subterranean fruits. Native to South America, it originated between southern Bolivia and northern Argentina from where it spread throughout the New World as Spanish explorers discovered its versatility. Today, farmers in Asia and Africa also cultivate it. It is grown under a wide range of environmental conditions in areas between 40 degrees South and 40 degrees North of the equator.
