Description Of The Tree

Botanical Description

The tree reaches a height of more than 50 m. The bole is usually straight, clear and cylindrical to 30 m in length, buttressed. The trunk diameter is up to 120 cm. Log is banned for international trading.(Cameroon)

Natural Habitat

Khaya anthotheca occurs in the intermediate zone between moist coastal and drier interior zones. It grows best in deep fertile soils on riverbanks. National conservation status in Cote d`Ivoire V, Liberia E, Uganda V/nt.

Natural Distribution

From Sierra Leone and Liberia to Gabon, it extends eastward to Uganda.

Plantations Available?

Tested and planted in some African countries. In most cases, mixed plantations with other species (Niangon, Okoume, Bilinga). The duration of the rotation is 40 years, to reach 60 cm in diameter.

Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Brown-colored deposits in heartwood vessels. Non-vestured pits. Vessels per mm2 6 to 10 (medium). Simple perforation plat Occasionally axial parenchyma in marginal or in seemingly marginal bands. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally prismatic crystals in non-chambered axial parenchyma cells. 3 to 4 cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays of two distinct sizes. Occasionally rays storied. Rays 1 to 2 seriate. Larger rays more than 4 seriate. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Septate fibers present. Fibers with simple to minutely bordered pits.

General Wood Description


Light and pleasant odor.


The sapwood is creamy white to yellowish white, it has a thickness of 5 cm. The heartwood is pink to light red brown, it is clearly demarcated. The silver figure is fine.

COLOR INDEX (1=Black, 7=Light yellow,white)



The grain is slightly but systematically interlocked.


The wood is typically medium in texture.


This wood is frequently low in luster.

Natural Durability

Moderately durable to decay. Without preservative treatment, this species can be used only under risk of occasional re-humidification. It is not suited for uses with risks of permanent or long-lasting humidification. Sensible to termites attack. The heart
