Peanuts belong to the pulses – i.e. they are not really nuts but more related to peas and beans. The name peanuts shows that relation, and their other name “ground nuts” indicates that they grow near the ground. Initially, the peanut plant was at home in the Andes in South America, today they are grown in tropical and subtropical climates all over the world. The pericarp is oblong, slightly bent, with a net-wise surface structure, it contains two to three almost egg-shaped light-brown seeds.
