'''Arachis hypogaea ''' is an annual plant with erect or prostrate stems up to 70cm long. The root system consists of a well-developed taproot with many lateral roots, up to 135cm deep, but generally restricted to the upper layers of the soil. The peanut is a very commonly used food plant, valued mainly for its edible seed and oil, but also having medicinal and other uses. It is widely cultivated throughout the tropics and sub-tropics for its seed, there are many named varieties.

{{Flower|Bisexual|Axillary|Yellow||Flowers pea-like, enclosed between two bracts, one simple, subtending a very short peduncle, the other bifid, subtending the pedicel; sessile, but appear to be stalked after growth of a tubular hypanthium just before anthesis. Petals, orange, yellow, cream or rarely white; Stamens 10, sterile filaments usually 2, anthers 8 (sometimes 9, rarely 10), 4 globose, uniloculate, alternating with 4 oblong, 3 of which are biloculate and 1, opposite the standard, uniloculate. The tip of the ovary, bearing from 1–5 ovules, grows out from between the floral bracts, bearing with it the dried petals, calyx lobes and hypanthium; creating a unique floral stucture—the peg. The peg quickly turns down toward the soil and thrusts its tip with its ovules several centimeters into the soil where the tip turns horizontally and develops into the pod. }}
