from The Century Dictionary and Cyclopedia
- n. A giant cactus with simple columnar stems, Cereus marginatus, much used for hedges in Mexico, especially in the states of San Luis Potosí, Hidalgo, and Guanajuato. It takes its common name from the resemblance of its rows of parallel stems to the pipes of an organ. Its flowers are inconspicuous and its fruit, unlike the pitahayas of many other species of Cereus, are not edible.
- n. A name given to other columnar cacti, including Cereus eburneus of southern Mexico, which bears edible fruit and is also planted in hedges, and the giant saguaro of the south-western United States, Cereus giganteus. See saguaro and pitahaya.
