Samanea saman is known under a wide range of common names, such as Saman, Rain Tree or Monkey Pod. It is often placed in the genus Samanea, which by yet other authors is subsumed in Albizia entirely. This legume tree is native to the mainland neotropics, from Mexico south to Peru and Brazil, but has been widely introduced to the Pacific islands, including Hawaiʻi.

Saman is a wide-canopied tree with a large symmetrical crown. It usually reaches a height of 25 meters and a diameter of 40 meters. The leaves fold in rainy weather and in the evening, hence the name Rain Tree and '5 o'clock Tree'(Pukul Lima) in Malay. Several lineages of this tree are available e.g. with reddish pink and creamish golden colored flowers.
