Diagnostics:

Averrhoea bilimbi is a small tree commonly cultivated for its fruits. It is very easy to identify from its clustering compound leaves and its often drooping leaflets. The leaflets are covered with fine hairs making them very smooth and pleasant to touch. A close relative to the Star Fruit (Averrhoa carambola), their flowers are also borne on the stem and branches.


Interesting Facts:

The fruit is very sour due to its high oxalic acid (Ken & Robert, 2011). They are used to make chutneys and prickled relishes (Ng, 2010).
