largest of the Ceratozamias, this one is from Mexico and also from several areas of central America south of Mexico (Belize and Guatemala). Caudex/trunk up to 6' tall and leaves up to 9' long... large curved leathery deep green, somewhat pendant leaflets. Some feel this is just a huge version of C mexicana.
