Stems: Solitary, erect stems, to 30 m tall (usually shorter in cultivation), up to 20 cm in diameter. Stems of younger individuals are covered with old leaf bases; older palms with smooth, columnar stems ringed by faint leaf scars. Leaves: Palmate, induplicate, with an elongated petiole, a more or less circular blade to 1 m across, and stiff leaf segments. The upper leaf surface is green; the undersurface, waxy gray to silver; leaftips, bifid. The petiole is armed with curved teeth and is not split at the base. Flowers and fruits: Inflorescence is longer than leaves and much branched. The flowers have both male and female parts. Fruits are up to 2 cm long and 9-17 mm in diameter, turning black when ripe.
Copernicia prunifera, the carnuba wax palm, but C. prunifera has spirally arranged leaf bases that persist around the stems, is usually no more than 12 m tall, and has leaf blades 1.5-2 m wide with heavy wax on both upper and lower surfaces.
