This tree can be seen at several of our mangrove forests, including Pulau Tekong, Pulau Ubin, Pulau Semakau, Pasir Ris, Sungei Buloh Wetland Reserve, Kranji, Mandai and Woodlands Town Garden.
It occurs on the landward fringe of mangrove forests. The bark is fissured and reddish-brown. It relies on its roots to exclude salt from entering the plant through a process called ultrafiltration.
It has simple, alternate, obovate leaves with a rounded tip. There is a small notch at the tip.
The flowers are white and occur in clusters. They are rich in nectar with a weak scent, and are pollinated by insects.
The small fruits are fibrous and compressed sideways, with a prominent persistent style. They are buoyant and dispersed by water.
Fruits may turn brown with age.
The wood is hard and durable, and is used for the building of bridges, ships and furniture. The bark is sometimes used for tanning purposes. It is also used for firewood.
