Natural Habitat
Aningeria trees are reported to be widespread in tropical and subtropical forests of Africa.
Natural Distribution
The genus is widespread in tropical Africa, particularly common in parts of East Africa.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 100 to 150 micras (small). Non-vestured pits. Vessels per mm2 10 to 20 (abundant). Simple perforation plates. Vessel-ray pits coarse in marginal rows Axial parenchyma in continuous tangential lines or fine bands. Non-crystals in axial parenchyma cells. Prismatic crystals in short chains in chambered axial parenchyma cells. 5 to 8 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to Rays more than 10 per mm (abundant). Rays non-storied. Rays 1 to 4 seriate. Silica bodies in the ray cells. Heterogeneous rays and/or multiseriate heterogeneous rays. Non-septate fibers. Fibers with simple to minutely bordered pits.

General Wood Description
Odor
Light and pleasant odor.
Color
The heartwood is yellowish white to pale brown or pinkish brown, it is not clearly demarcated.
COLOR INDEX (1=Black, 7=Light yellow,white)
6
Grain
Straight or slightly interlocked, sometimes with an influence on further processing operations.
Texture
Texture is mostly fine to medium.
Luster
The wood surface is moderate in luster.
Natural Durability
Slightly durable to decay. This species needs preservative treatment for uses with risks of occasional re-humidification. It is not suited for uses with risks of permanent or long-lasting humidification. Heartwood is sensible to termites and Lyctus attack
Natural durability index (1= Very high durability, 7=Vey low durability)

Internal Growth Stresses
No residual growth stresses are found.
Resistance To Impregnation
Easy to treat with a full penetration of the preservative products using vacuum-pressure method.
