Question: In what region would you probably find both Beaucarnea and Cybistax?
Related documents: [0]  [DOC] Beaucarnea is a genus of flowering plants native to Mexico and Central America. In the APG III classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). "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. [END] 
[1]  [DOC] Cybistax is a genus containing a single species, Cybistax antisyphilitica (Mart.) Mart., a flowering and economic timber tree from tropical Central and South America. These semi-deciduous plants have greyish green, opposite, palmately compounded leaves and close-grained, light-colored wood good for furniture. In early spring, the plants bear showy clusters of bright yellow, funnel-shaped flowers 2-2.5 cm wide at branch ends. Pods are 25–50 cm long, straight, pendulous and brown with thin, flat seeds inside. The seeds have papery wings. [END]
