Description Of The Tree
Botanical Description
The tree may reach up to 30 m, with a diameter up to 120 cm. The bole is straight and slender, from 8 to 15 m long.
Natural Habitat
Musanga cecropioides is typical of secondary forests, common on old farms in closed forests.
Natural Distribution
West, Central and East Africa, from Sierra Leone to Uganda.
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). Tyloses thin walled. Non-vestured pits. Vessels per mm2 less than 6 (rare). Simple perforation plates. Vessel-ray pits lar Paratracheal axial parenchyma thin 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 non-storied. Rays 1 to 4 seriate. Prismatic crystals in radial alignment in procumbent ray cells (chambered cells). Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Body ray cells procumbent with mostl Non-septate fibers. Fibers with simple to minutely bordered pits.

General Wood Description
Color
The heartwood is pale yellow, pale brown or white, turning to a pale yellow-white with age, it is not clearly demarcated.
COLOR INDEX (1=Black, 7=Light yellow,white)

Grain
Straight; grain has no particular influence on drying, machining and finishing qualities.
Texture
The texture of the wood is frequently coarse.
Luster
The surface of the wood is naturally low in luster.
Natural Durability
Not durable; important risks of decay attacks at any processing step, from logs up to final products. It must receive preservative treatment. Sensible to termites attack. The heartwood is sensible to Lyctus attacks.
Natural durability index (1= Very high durability, 7=Vey low durability)

Internal Growth Stresses
For this species no growth stresses are reported.
Silica Content
Silica Content: Negligible contents of silica are found in timber of this species. Amounts over 0.05% may affect the wood processing. Silica Value: 0
Resistance To Impregnation
Easy to treat with a full penetration of the preservative products using vacuum-pressure method.
