Beaucarnea recurvata or Nolina recurvata

It is an evergreen perennial growing to 15 feet 6 inches (4.72 m) with a noticeable expanded caudex, for the purpose of storing water inside. The single palm-like stem produces terminal tufts of strap-shaped, recurved leathery leaves, sometimes hair lock-shaped in the ends, and with occasional panicles of small white flowers once the plant reaches over 10 years of age. There are 10 different species of this plant, according to the Institute of Ecology in Xalapa, state of Veracruz, which runs the Jardín Botánico Francisco Javier Clavijero botanical garden, where over 400 Beaucarneas are exhibited and more are grown in greenhouses for conservation purposes, in the "Colección Nacional de Beaucarneas" (Beaucarneas National Collection)
