Beaucarnea is a genus of flowering plants native to Mexico and Central America.[1] In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae[2]). Beaucarnea is sometimes treated as a synonym of the genus Nolina, with the species being then transferred to that genus. However, recent research shows that Beaucarnea should treated as an independent genus.[3]

The species are small tropical xerophytic trees growing to 6–10 m tall, with a trunk 20–40 cm diameter with a flared base; young plants are single-stemmed, branching only after flowering. The leaves are evergreen, linear, strap-shaped, 0.5-1.8 m long and 1.5–2 cm broad, leathery in texture, with a finely serrated margin. The flowers are produced only on old trees, forming on large panicles 75–110 cm long, the individual flowers numerous but very small (1.5 mm diameter), greenish-white, with six tepals.
