Sub-canopy tree up to 26(-45) m tall and 61(-150) cm dbh. Stipules absent. Leaves oposite to
slightly alternate, simple, penni-veined, glabrous. Flowers ca. 45 mm diameter, blue-purple, placed
in erect panicles. Fruits ca. 22 mm long, green-yellow-brown, dehiscent capsules
splitting in six elongate parts. Seeds small, winged.
A deciduous or semi-deciduous small to medium-sized or rarely large tree up to 40(45) m tall;
bole fairly straight to crooked, branchless for up to 18 m, up to 100(-150) cm in diameter, often
fluted and sometimes with small buttresses, bark surface smooth or with
small papery flakes, grey to light fawn-brown mottled, inner bark fibrous,
grey-fawn to yellow, turning dirty mauve or purple upon exposure; crown
usually bushy and spreading. Leaves opposite, distichous, simple, entire, stipules minute or absent.
Flowers in a large, axillary or terminal panicle, often showy, calyx funnel or
bell shaped, 6(9) lobed, petals often 6, inserted near the mouth of the
calyx tube, white to pink or purple, clawed, wrinkled, stamens many, in
several rows, ovary superior, 3-6 locular with many ovules in each cell,
style 1. Fruit a large woody capsule on the persistent calyx. Seed with an apical wing.
In open vegetation types, often coastal areas, in regrowth or in swamps,
also planted a lot. Usually on alluvial sites and along
rivers with sandy to clay soils at medium altitudes. Trees shed leaves in the dry season. Saplings
flower when only a few years old but viable seed production begins at 15 years old.
Flowering is frequent, usually annually or even twice a year. Each flower lasts for only
2-3 days. In the Philippines, the tree flowers in April-June, in Java in July-
October, and in Papua New Guinea in May-July, although flowers and
fruits may be found throughout the year. Pollination is by large bees and
seeds are dispersed by wind.
Ornamental. Also used for fire wood. The timber is resistant to termites. Roots, stems and leaves
contain hydrocyanic acid (poisenous). A decoction of the bark is used against diarrhoea and
abdominal pains. A leaf poultice is used to relief malarial fever and is applied on cracked
feet. A preparation from dried leaves, known as banaba, is widely used in the Philippines
to treat diabetes and urinary problems. Due to the tree¡¯s dense and widespreading root system,
it is used in erosion control.
Pan-tropical. Originally from India and southern China to New Guinea and Australia.
