The Saga can grow up to 25 m in height, with brown-grey bark and a spreading, rounded crown. The tree is naturally found from India, Sri Lanka through to Southeast Asia and Queensland, Australia. In its natural habitat, the tree is deciduous, shedding its fine bipinnate leaves annually although it does so briefly every 6-8 months in Singapore.

Its small creamy yellow, inconspicuous star-shaped flowers give way to dark brown fruits pods, which then twist and open to expel small, hard scarlet seeds. The attractive seeds are eagerly gathered by children to play with and for playing games, such as congkak. Despite being a common shade tree in our landscape, the Saga is not a native species to Singapore.

The introduction of the Saga first came about as an experiment of suppressing Lalang (Imperata cylindrica) (opens in new tab) between 1883 to 1885 by Nathaniel Cantley, the then-superintendent of Singapore Botanic Gardens. Henry Nicholas Ridley later planted this species to provide shade to nutmegs trees and shade out the Lalang grass. It was only in the 1970s and 1980s that the species became a common roadside tree. The earliest recorded Herbarium specimen taken from this tree was dated in 1900, so this tree would well be over 100 years old.
