Bitterwood Tree
Picrasma
A genus of deciduous trees and shrubs known for their extremely bitter bark and medicinal …
Growing tall within the tropical rainforests of West and Central Africa, Odyendyea klaineana produces lightweight timber and medicinal extracts utilized by local communities. This canopy-level species thrives in humid forest environments and plays a key structural role in its native ecosystems.
Also known by its synonym Hannoa chlorantha, the tree is adapted to high rainfall and acidic soils. It remains a wild species harvested mainly from natural forest stands.
This medium-to-large tree can reach heights of 25 to 35 meters, featuring a straight, cylindrical trunk that can measure up to 100 cm in diameter. The bark is smooth and ranges in colour from greyish to pale brown.
The compound, pinnate leaves are composed of 5 to 11 oblong-elliptic leaflets. Small, yellowish-white or greenish-yellow flowers bloom in large panicles, developing into ovoid drupes that turn dark purple or black at maturity.
The lightweight, soft wood is harvested under local names and used for interior joinery, light construction, crates, and plywood. Traditional herbalists prepare decoctions from the bark and roots to treat high fevers, malaria, and digestive complaints.
The tree's bitter compounds also make its bark extracts useful as a natural deterrent against household and agricultural pests. Due to its soft nature, the wood is easily worked with manual and machine tools.
The species contains specialized bitter substances that defend the living tree against herbivorous insects. A historical botanical specimen of this tree was collected in Angola by the noted German botanist Hugo Baum during his south-central African expedition.
