Arachis hypogaea (peanut)
Overview
Arachis hypogaea, commonly called peanut or groundnut, is unusual in that its flowers are pollinated above ground, but the flower stalk and ovary then extend down into the ground to produce fruits below ground. The peanut was domesticated in South America, perhaps around Paraguay, Bolivia, or Peru. Cultivated peanuts are tetraploid, with parental genomes probably contributed from the diploid species A. duranensis and A. ipaensis, which occur in Argentina, Bolivia, and Paraguay.
