Cybistax is a genus of trees in the family Bignoniaceae. It contains a single species, Cybistax antisyphilitica, a tree from tropical North and South America.[1]
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.
