Obeche

Triplochiton scleroxylon is native to the tropical forests of West and Central Africa.

• Distributed from Guinea and Sierra Leone eastward through Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, and into the Republic of Congo and Democratic Republic of Congo
• Found in semi-deciduous and deciduous tropical forests, from sea level to approximately 700 m elevation
• Common in both primary and secondary forests, and often one of the first large trees to colonize abandoned farmland
• Prefers regions with annual rainfall of 1,200-2,000 mm and a distinct dry season
• A gregarious species that can form nearly pure stands in favorable conditions
• First described by the German botanist Karl Moritz Schumann
• The species is the source of the famous "African whitewood" exported to Europe for over a century

A large, buttressed, deciduous tropical tree.

Trunk and Crown:
• Height: 30-45 m (occasionally reaching 55 m) with a massive, cylindrical bole
• Trunk diameter: 80-150 cm (up to 200 cm in exceptional specimens)
• Buttresses: very large, prominent, thin, extending 2-4 m up the trunk
• Bark: pale gray to yellowish-gray, smooth to slightly rough, peeling in thin scales
• Crown: large, spreading, with massive ascending branches
• Deciduous, shedding leaves during the dry season

Leaves:
• Simple, alternate, palmately lobed (3-5 lobes), resembling maple leaves
• Large, 15-30 cm across, with serrated margins
• Dark green above, paler and sometimes stellate-pubescent beneath
• Petioles 5-15 cm long

Flowers:
• Small, creamy-white, with 5 petals, approximately 1 cm in diameter
• Arranged in large, showy, terminal panicles 15-30 cm long
• Flowering occurs at the beginning of the dry season when the tree is leafless
• Insect-pollinated, particularly by bees and butterflies

Fruit:
• A distinctive, 5-winged samara 5-8 cm long
• Wings are membranous, enabling wind dispersal
• Profuse fruit production occurs during the dry season

Obeche is a light-demanding pioneer species in West African forest ecosystems.

• A classic pioneer species that rapidly colonizes forest gaps and abandoned agricultural land
• Produces enormous quantities of winged seeds that disperse widely on wind currents
• One of the most abundant large tree species in semi-deciduous forests of West Africa
• Flowers profusely during the dry season, providing nectar when few other trees are flowering
• Can form almost pure stands in secondary forest regrowth
• Roots help stabilize soil in forest regeneration areas
• Plays an important role in forest succession, preparing conditions for shade-tolerant climax species
• Supports populations of birds, insects, and mammals that feed on its seeds

Obeche is relatively easy to cultivate in tropical environments.

• Requires tropical conditions with annual rainfall of 1,200-2,000 mm and a distinct dry season
• Prefers well-drained, deep, fertile loamy or sandy-loam soils
• Propagation is by seed; winged fruits should be collected during the dry season
• Seeds germinate within 7-21 days under warm conditions
• Seedlings grow rapidly, often reaching 2-3 m in the first year
• Requires full sun for optimal growth; intolerant of shade after the seedling stage
• Planting densities of 200-400 trees per hectare for timber plantations
• Rotation cycles of 20-30 years produce commercial-grade timber
• Coppices readily from cut stumps
