Pink-eyed
pong pong tree
Cerbera manghas
Family Apocynaceae
updated Aug 09
Where seen? This beautiful tree with pretty pink-eyed white
flowers is rare. Even in the past it was rare, among the locations
where it was found were Pasir Panjang and Katong, shores now already
reclaimed. It now found in the wild on Chek Jawa, with a large stand
at Pulau Semakau. They are also planted at St. John's Island. According
to Giesen, it is found in coastal swamp forests or on beaches, preferring
well drained sandy soils, exposure to sea breezes but not regularly
inundated by tides.
Features: Tree up to 15m tall,
but in Singapore usually shorter. Leaves (12-30cm long) oval, dark
green and glossy, held in dense spirals at the tips of the twigs.
Leaves generally smaller than that of the more common Yellow-eyed
Pong pong tree (Cerbera odollam). Flowers (about 5cm) white
with pink centre, first orange pink then reddish pink. The flowers
appear at the tips of the twigs. Produces a white sap. Fruits (5-7cm)
often paired and mango-shaped or oblong. First green then pink, rosy
purple and finally black. The fruits float are dispersed by water.
When they wash up, often only the fibrous husk is left, around a hard
stone. Bark fissured, flaky, grey to brown with lenticels.
Human
uses: See the fact sheets on Cerbera
species in general for more about their uses.
Status and threats: The tree
is listed as 'Critically Endangered' on the Red List of threatened
plants of Singapore.
