Description and Ethnobotany
Growth Form | It is a small or medium-sized tree up to 20 m tall. |
---|---|
Foliage | Its alternate, shortly-stalked to stalkless leaves possess thinly leathery leaf blades that are green, drop-shaped-oblong to narrowly drop-shaped, 5–42 by 2–16 cm, slightly toothed at the margins, with short tips and yellow veins. |
Flowers | Its hanging flowering shoots are 20–100 cm long. Its large, shortly-stalked flowers are fragrant, 7.6–10 cm wide, with red sepals, white petals (sometimes tinged pink), and white, pink or red stamens. |
Fruit | Its fruits are usually 1-seeded, oblong or rather pear-shaped, green or flushed reddish when ripe, and 3–9 by 2–6.4 cm, with four, faint grooves. Its seed is 2–4 cm long. |
Habitat | It grows in the landward side of mangrove forest, primary and secondary forests on the banks of tidal creeks, rivers and swampy areas, and on sandy or rocky shores, up to 900 m altitude. It occurs locally in Western Catchment Area, and in the vicinity of MacRitchie Reservoir. |
Associated Fauna | It is the food plant for caterpillars of the moths Attacus atlas (Atlas Moth), Gnathmocerodes tonsoria, and Thosea andamanica. Its flowers are pollinated by bats and moths. |
Cultivation | Grows well in slightly saline, heavy soils. It can be propagated by seed, or stem cuttings. |
Etymology | Latin Barringtonia, after Hon. Daines Barrington (1727–1800), English naturalist; Latin racemosa, flowers growing in racemes, referring to the plant’s racemous flowering shoot consisting of a central axis with stalked flowers along it with the youngest at the tip and the older ones progressively lower |
Ethnobotanical Uses | Timber & Products: The wood is utilized as firewood, and for construction. The bark provides a source of fibre. Others: The powdered bark and all other parts of the plant were exploited as a fish poison, while their extracts may be used as an insecticide. The bark and roots are used as tanning agents as they contain high levels of tannin. It is occasionally cultivated as an ornamental tree along roadsides. |
Landscaping Features
Landscaping | This tree is cultivated in parks, large gardens and and is suitable for roadsides. It has attractive red and white flowers on long, hanging flowering shoots, and large reddish fruits. It can tolerate a wide range of soil conditions, so making it suitable for most sites, including beaches to edges of ponds and reservoirs. |
