A large deciduous tree that grows up to 40m in height. Crown is dense, dome-shaped, wide-spreading, drooping. Leaves are simple pinnate compound. Flowers are yellow and occur in large bunches of 15-30 cm long. Fruits are flattened, disc-like pods with papery wings about 5cm in diameter, 1 or more seeds in each. A cultivated species in Singapore.
The floral buds of the Angsana develop high up on the crown, unnoticed by anyone, until the right stimulus triggers the buds on the crown to bloom in yellow simultaneously. This brilliant display of colour lasts only for a day, after which the tree lays a soft carpet of yellow flowers on the ground beneath it. On 5 June 2014, a few construction workers resting under this Tree were drawn to the sight of a heart-shaped tree stump, but what they found next, was nothing short of heart-pounding. Nestled within a crevice in the Tree within two branches was a war relic. The Explosive Ordnance Disposal (EOD) team from the Singapore Armed Forces (SAF) was called in to investigate & found the device to be a World War II hand grenade. With a police security cordon in place, they worked through the night to dispose of the bomb. The war relic was successfully disposed of at 12.45am, 6 June 2014. With this war relic time stamp on this Tree, it is probable that this Tree existed here since the 1940s, at least. This Heritage Tree had a girth of 6.3m when measured in Year 2001.
