Century Dictionary and Cyclopedia
    • n teosinte A grass, Euchlœna luxurians, native in Mexico and Central America, introduced into cultivation in various parts of the world. It is closely allied to the Indian corn, having the male flowers in a tassel at the top, the seed, however, borne not on a cob, but on slender stems from the joints, inclosed in a loose husk. It is an annual, reaching the height of 12 feet, suitable for forage and perhaps the most prolific of forage-plants, sending up sometimes sixty or eighty shoots, and springing up again when cut. It endures drought fairly well, though preferring humid soil. Its success in the southern United States is hindered by its not ripening its seed; it is found to do so, however, in some subtropical localities. Also called Guatemala grass.
