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. |
Fruit | 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 | 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. |
