Arachis hypogea.

Botanical name: 

ARACHIS HYPOGEA, L. Ground Nut, Pea Nut. Cultivated from Maryland to Florida. Erroneously called Pistachoe Nut in Carolina, the name belongs to the Pistacia of Sicily and Syria. Called Pindars in the West Indies. Cultivated by the Indians from Florida to Brazil before Columbus, by the name of Mani. Yet by the Creek tribes, who raise large crops in pure sand. The seeds or beans are oily, they produce much oil fit for all uses; commonly eaten roasted in the shell or pod; nutritive, demulcent and pectoral. A kind of chocolate can be made with them, quite inferior, though taste similar.

Medical Flora, or Manual of the Medical Botany of the United States of North America, Vol. 2, 1830, was written by C. S. Rafinesque.
