BILINGA

Bilinga is a tropical species native to West and Central Africa. The tree gives a golden yellow to yellow-orange wood that is naturally very durable. Bilinga is therefore particularly adapted to uses requiring solid materials that are resistant to external aggressions, such as shipbuilding or hydraulic works in marine environment. The exotic species Bilinga naturally covers class 5: it can be used in marine environment and brackish water.

The tropical tree Bilinga is a large tree of the forests of West and Central Africa. It is between 30 and 40 m high, with a diameter up to 1.20 m. The bole is cylindrical, generally slender, very straight, without buttresses. It sometimes has small bases. It is covered with a grey-brown scaly bark, sometimes turning to orange-yellow, often cracked.

We recognize the Bilinga in forest thanks to its inflorescences and its spherical fruits. The fruits, with pulpy and fragrant flesh, are considered edible.
