Beaucarnea is a genus of flowering plants native to Mexico and Central America. [2] In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae [3] ). 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 be treated as an independent genus. [4]

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.

<span class="mw-page-title-main">Families of Asparagales</span>

The Asparagales are an order of plants, and on this page the structure of the order is used according to the APG III system. The order takes its name from the family Asparagaceae and is placed in the monocots. The order is clearly circumscribed on the basis of DNA sequence analysis, but is difficult to define morphologically, since its members are structurally diverse. The APG III system is used in World Checklist of Selected Plant Families from the Royal Botanical Gardens at Kew. With this circumscription, the order consists of 14 families with approximately 1120 genera and 26000 species.
