Have a look at Wikipedia: For people who don't know anything but call specialists.

The peanut, or groundnut (Arachis hypogaea), is a species in the legume "bean" family (Fabaceae). The cultivated peanut was probably first domesticated in the valleys of the Paraguay and Parana rivers in the Chaco region of Paraguay and Bolivia.[1]  It is an annual herbaceous plant growing 30 to 50 cm (0.98 to 1.6 ft) tall. The leaves are opposite, pinnate with four leaflets (two opposite pairs; no terminal leaflet), each leaflet 1 to 7 cm (⅜ to 2¾ in) long and 1 to 3 cm (⅜ to 1 inch) broad. The flowers are a typical peaflower in shape, 2 to 4 cm (¾ to 1½ in) across, yellow with reddish veining. After pollination, the fruit develops into a legume 3 to 7 cm (1.2 to 2.8 in) long, containing 1 to 4 seeds, which forces its way underground to mature. Hypogaea means "under the earth."
