Albizia saman

MEDICINAL PROPERTIES
Rain Tree is a wide-canopied tree with a large symmetrical crown. It usually reaches a height of 25 m (82 ft) and a diameter of 40 m (130 ft). The leaves fold in rainy weather and in the evening, hence the name “rain tree” and “five o’clock tree” (Pukul Lima) in Malay. Several lineages of this tree are available, e.g., with reddish pink and creamish golden colored flowers.
During his 1799–1804 travels in the Americas, Alexander von Humboldt encountered a giant saman tree near Maracay, Venezuela. He measured the circumference of the parasol-shaped crown at 576 ft (about 180.8 m ), its diameter was around 190 ft (about 59.6 m), on a trunk at 9 ft (about 2.8 m) in diameter and reaching just 60 ft (nearly 19 m) in height. Humboldt mentioned the tree was reported to have changed little since the Spanish colonization of Venezuela; he estimated it to be as old as the famous Canary Islands dragon tree(Dracaena draco) of Icod de los Vinos on Tenerife.
