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. The Building at No. 10 Pender Road was built in 1909. It was called the 'Golden Bell' and was built as the home of Mr Tan Boo Liat, a grandson of Mr Tan Tock Seng, the philanthropist whose name the famous Hospital was named after. Mr Tan B L sold the 'Golden Bell' some time after it was built. It is recorded that Dr Sun Yat Sen spent a night in the "Golden Bell" during a visit to Singapore. It is likely that this Angsana Heritage Tree had withstood the ravages of time since the early half of the 20th Century.
