rain treerain tree
A tropical American tree (Albizia saman) , widely planted in warm climates as a landscaping and shade tree for its wide, spreading, even canopy.
Origin of rain treeTranslation of Peruvian Quechua tamya kaspi tamya rain kapsi wood, stick, tree ( the tree being so called because insects feeding on the tree, as well as the nectaries on its leaf stems, secrete large amounts of fluid moistening the earth beneath the tree and sometimes creating a fine rain as it drops; the designation rain tree ) ( perhaps becoming popular in English because the continual dampness under the tree allows green vegetation to flourish near the tree when the surroundings are dry, and because its leaves close on overcast days and at night, allowing rain to fall through the dense canopy, and release accumulated water when they open )
(plural rain trees)
- an ornamental tropical American tree (of uncertain taxonomy) having bipinnate leaves, globose clusters of flowers with crimson stamens, and sweet-pulp pods eaten by cattle
so called from the belief that it exudes water from its leaflets
