Description Of The Tree
Botanical Description
The tree reaches a height of 50 m, with diameters from 100 to 1.3 m. The bole is straight, cylindrical up to 26 m in length, generally unbuttressed, with a swollen base.
Natural Habitat
Anopyxis klaineana is a timber species which occurs in some abundance especially in wetter evergreen rain forests and in montane forests.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 200 micras or more (large). Vessels per mm2 less than 6 (rare). Simple perforation plates. Occasionally multiple perforation plates. Scalariform perforation plate Paratracheal axial parenchyma scanty and/or vasicentric. Prismatic crystals in short chains in chambered axial parenchyma cells. 4 to 10 rays per mm (medium). Rays non-storied. Larger rays more than 4 seriate. Occasionally prismatic crystals in the ray cells. Body ray cells procumbent with over 4 rows of upright and/or square marginal cells (Kribs-I). Non-septate fibers. Fibers with distinctly bordered pits.

General Wood Description
Color
The sapwood is paler than heartwood. The heartwood is reddish brown or yellow-brown , it is clearly demarcated.

Grain
Straight; grain has no particular influence on drying, machining and finishing qualities.
Texture
This species is reported to have a medium to coarse texture.
Luster
This wood is frequently 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. Resistant to termites attack. Heartwood is sensible to Lyctus attacks.
Natural durability index (1= Very high durability, 7=Vey low durability)

Internal Growth Stresses
No residual growth stresses are found.
Silica Content
Silica Content: It is reported to have a negligible amount of silica. Contents over 0.05% may affect wood processing. Silica Value: 0.02
Resistance To Impregnation
Easy to treat with a full penetration of the preservative products using vacuum-pressure method.

Drying Defects
Ease of Drying: Boards 25 mm thick take about 3 months to air dry. Drying Defects: When seasoned with care, end-splitting and surface checking are not significant during drying. Kiln Schedules: The timber kiln dries rapidly but marked collapse may occur in early stages of seasoning. This can be remedied by reconditioning.

Workability
Sawing
Sawing of this species requires powerful equipment.
Rotary Veneer Cutting
Not suitable for veneering.
Sliced Veneer
Not suitable for veneering.
Blunting Effect
Moderate blunting effect; stellited blades for sawing and carbide tools for machining are advised.
Machining
It needs powerful tools for processing. Possible difficulties caused by interlocked grain are reported.
Planing
Moderately easy; tools must be cautiously sharpened.
Moulding
Moderately easy; tools must be cautiously sharpened.
Turning
30
Boring
Moderately easy; tools must be cautiously sharpened.
Mortising
Moderately easy; tools must be cautiously sharpened.
Nailing
Pre-boring is necessary.
Gluing
Difficult to glue because of high density.
Sanding
Easy to perform; it gives good results.
Polishing
Needs pre-coating.
Response To Hand Tools
Working with hand tools is difficult.
