Where seen? This tree with hanging garlands of pretty pink
fluffy flowers is now rare in the wild. It is, however, being planted
in some of our coastal parks and reserves. Wild trees are found in
damp places near mangroves, tidal rivers, sandy or rocky shores, freshwater
swamps, peat swamp forests. And even banks of tidal creeks and muddy
ditches in rice-fields in Malaya.

bats. Flowering occurs year round.
Fruit (3-8cm long) egg- or pear-shaped, sometimes weakly angled or

Attacus atlas (Atlas Moth), Gnathmocerodes tonsoria,

concentrated mainly in the seeds but also found in other parts of
the plant. According to Burkill, the leaves are used in a poultice

young leaves are eaten raw in Eastern Malaysia, and in the Philippines
the fruits are used to poison wild pigs.
