The Yellow Flame is a medium-sized tree that can grow up to 20 m or more in height. It has a wide-spreading umbrella-shaped crown, and slightly rough light grey bark. Its leaves are bipinnate with many tiny leaflets. The Yellow Flame has bright yellow blooms which are about 3 cm in size and occur in bunches. Its fruit is a pod that is 5–10 cm long and purplish brown in colour.
This species is native to Southeast Asia, including Singapore, where it is Critically Endangered in the wild according to the Singapore Red Data Book (2nd Edition). It is, however, widely planted along roadsides for its wide beautiful crown and bright yellow, full blooms which occasionally cover the entire tree.
