Aningeria spp.

Aningeria

Family: Sapotaceae

Other Common Names: Agnegre, Anegre (Ivory Coast), Landosan (Nigeria), Mukali, Kali (Angola), Osan, Mutoke (Uganda), Mukangu, Muna (Kenya).

Distribution: The genus is widespread in tropical Africa, particularly common in parts of East Africa.

The Tree: May reach a height of 180 ft with a clear cylindrical bole to 80 ft; trunk diameters above tall symmetrical buttresses 3 to 4 ft.

The Wood:

General Characteristics: Heartwood yellowish white, pale brown, or pinkish brown, darkening slightly after exposure; sapwood not well demarcated. Texture medium to coarse; grain usually straight, sometimes wavy; lustrous; faint cedarlike odor.

Weight: Basic specific gravity (ovendry weight/green volume) 0.40 to 0.48; air- dry density 30 to 36 pcf.

Mechanical Properties: (First two sets of data based on the 2-in. standard, the third set on the 2-cm standard.)

Janka side hardness 740 to 1,250 lb for dry material. Amsler toughness 204 in.-lb. for dry material (2-cm specimen).

Drying and Shrinkage: Seasons well without degrade. Kiln schedule T6-D2 is suggested for 4/4 stock and T3-D1 for 8/4. Shrinkage green to ovendry: radial 3.8%; tangential 7.0%; volumetric 11.8%.

Working Properties: Generally reported to saw and machine well, but some species are silicious and have a blunting effect on cutters; rather difficult to finish; cuts well on rotary lathe or slicer.

Durability: The wood is perishable, little resistance to attack by decay fungi and termites, liable to blue stain.

Preservation: Reported to have good treatability.

Uses: General carpentry, joinery, veneer and plywood, furniture components.
