Family Sapotaceae

Where seen? Among our favourite fruits, the Chiku tree
is often planted in gardens. Those seen growing wild often mark the
locations of 'kampongs' or villages that have long since been cleared.
It is a native of tropical America and is believed to have been first
brought by the Spaniards to the Philippines. It was previously known
as Achras zapota.
Features: A small tree (to about
10m). Leaves oval with pointed tips (6-15cm long) arranged in a spiral
at the branch tips. Flowers small, white with brownish or greyish
woolly calyx. The fruit is oval or round (6-7cm). The sweet flesh
is pinkish white to reddish brown and encloses about 10 black seeds.
Bark light grey becoming shallowly fissured.
The fruits are relished by bats. I've observed a steady stream of
Common fruit
bat (Cynopterus brachyotis) feasting on a fruiting Chiku
tree. Each bat clings onto the fruit that is almost as large as itself,
and gorges it.
Human uses: According to Burkill, while in Asia it is valued
for its fruits, in its native tropical America it is valued for its
timber and latex. The gummy latex called 'chicle' was used as an ingredient
in chewing gum. Burkill says it 'becomes plastic at the temperature
of the mouth'. It has since been replaced by synthetic gums. |
