Description and Ethnobotany

Growth Form It is a tree up to 30 m tall, with a round crown of shiny, large, dark green leaves.
Trunk The unbuttressed trunk has pinkish-grey bark.
Foliage Its spirally arranged, stalkless leaves possess leathery leaf blades that are shiny dark green, drop-shaped, and 15–52 by 7–21 cm. Its fresh leaves are pinkish-olive with distinct pink veins, and wither yellow to pale orange.
Flowers Its flowering stalk is 2 - 20 cm long,, found at the ends of the branches and more or less upright, unlike the hanging ones typical of other Barringtonia species. Each stalk contains 3 - 20 flowers. Its stalked flowers are bisexual, 15-cm wide, and appear fluffy because of the presence of numerous, white, pink-tipped stamens. Its strongly fragrant flowers also open around sunset in ones or two, in readiness for the nocturnal animal pollinators.
Fruits Its 1–2-seeded fruits are 7–10 cm wide, with a broad square base tapering to two rounded sepals. The fruits mature from green to brown. They hang from branches, and have a tough, corky-fibrous husk that aids in their dispersal by water. Its seeds are oblong, and 4–5 cm long.
Habitat It grows along sandy coasts and seashores. It occurs locally in Labrador Park.
Associated Fauna It is the food plant for moth larvae of Dasychira spp. and Thyas honesta. Fruit bats and night-flying moths are attracted to its flowers and act as pollinators.
Cultivation It can be propagated by seed.
Etymology Latin Barringtonia, after Hon. Daines Barrington (1727–1800), English naturalist; Latin asiatica, asian; referring to the natural distribution of the plant.
Ethnobotanical Uses Edible Plant Parts (Edible Fruits)
Food (Herb and Spice;Fruit & Vegetable : The cooked fruits (to remove the saponins) are edible.)
Medicinal ( Backaches and sore joints can be treated using the bark, leaves, and fruits. Rheumatism can be treated using the fresh leaves, while their juices are used to treat diarrhoea. Intestinal worms can also be expelled by ingesting the seeds.)
Timber & Products ( The wood is used to construct boats and huts. )
Cultural / Religious ( Heritage Tree: There is currently one individual of Barringtonia asiatica listed as Heritage Tree in Singapore. It can be found at Singapore Botanic Gardens. To find out more about this tree, please visit the Heritage Tree Register. )
[Others]: Oil extracts from the seeds are used as an illuminant. The fruits and seeds are used as fish poisons as they contain toxic saponins.
