Pneumatophores
Flowers with numerous white stamens and tiny, white petals. Fruit somewhat pear-shaped, crowned by the persistent sepals whose tips bend back to the stalk. Seeds white, flattened, tiny, buoyant.

Found at the front of the mangrove belt and usually on sandy soil. Use as firewood, house building and clogs. The fruits, when ripe, are eaten by Malays.
The leaves can be eaten both raw and cooked. One of the most frequently encounted mangrove species in Singapore.

For a comparison of the fruit forms of the different Sonneratia species.
