Microberlinia is a small genus of tropical African timber trees in the legume family Fabaceae (order Fabales). The genus contains only two species — Microberlinia bisulcata and Microberlinia brazzavillensis — both native to the rainforests of Cameroon and Gabon in west-central Africa. These large canopy trees are highly prized for their distinctive wood, which is commercially known as zebrawood or zingana, named for the striking dark-brown streaks on a pale cream background that resemble a zebra's markings. The timber is hard, heavy, and durable, making it a sought-after material for high-end furniture, flooring, veneers, and decorative woodwork. Microberlinia bisulcata in particular is one of the most economically important timber species of the Congo Basin forests. Both species are characteristic of lowland tropical rainforest and are notable emergent trees that can reach large dimensions. Due to intensive logging pressure, both species are considered threatened in their native range.
Distribution
Microberlinia is native to the lowland tropical rainforests of Cameroon and Gabon in west-central Africa. Both species occur within the Congo Basin forest zone, one of the largest tropical forest blocks on Earth.
Ecology
Both species are large emergent canopy trees of lowland tropical rainforest. They are characteristic of the Guineo-Congolian rainforest region and tend to occur in moist, humid lowland forest habitats in Cameroon and Gabon.
Conservation
Both Microberlinia bisulcata and Microberlinia brazzavillensis have been subjected to heavy commercial logging pressure for their prized zebrawood timber. This has led to significant population declines, and both species are considered threatened. Microberlinia bisulcata is listed as Endangered on the IUCN Red List due to ongoing habitat loss and overexploitation.
Taxonomy Notes
Microberlinia belongs to the subfamily Detarioideae (formerly placed in Caesalpinioideae) within Fabaceae. The genus was erected to accommodate African species previously associated with Berlinia, reflected in the name micro- + Berlinia. The genus is monotypically small, with only two recognised species.
