a name given to the tubers of several very different plants, but particularly to those of a plant belonging to the parsley family. These tubers or nuts are about four or six inches below the surface, at the termination of a long, slender root. They are brown, the size of chestnuts, of a sweetish taste, resembling the common chestnut. Swine are very fond of the nuts, and fatten rapidly where they are abundant. In some localities peanuts are called earthnuts.
