Known in Latin as Albizia saman, the Raintree is a species of flowering tree in
the pea family, Fabaceae, that is native to the Neotropics. Its range extends from Mexico south
to Peru and Brazil, but it has been widely introduced to South and Southeast Asia, as well as
the Pacific Islands, including Hawaii. Common names include saman, rain tree and monkeypod.
The name "rain tree" was coined in India, especially Bengal.
