Theobroma Cacao Linn. is a handsome tree, from twelve to twenty feet in height, growing in Mexico, the West Indies, and South America. [...] The fruit is an oblong-ovate capsule or berry, six or eight inches in length, with a thick, coriaceous, somewhat ligneous rind, enclosing a whitish pulp, in which numerous seeds are embedded. These are ovate, somewhat compressed, about as large as an almond, and consist of an exterior thin shell and a brown oily kernel. Separated from the matter in which they are enveloped, they constitute the cacao, or chocolate nuts, of commerce.
