Wood Identification

Anatomic Description Of Wood

Wood diffuse porous. Occasionally tangential diameter of vessel lumina 200 micras or more. Vessels per mm2 5 to 20. Vessels per mm2 more than 20 (very abundant). Simple perforation plates. Occasionally intervessel pits small, 7 micras or less. Intervessel pits Axial parenchyma absent or extremely rare, non visible with magnifying glass (8x). Occasionally apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Paratracheal axial parenchyma scanty and/or vasicentric. Occasionally paratracheal axial parenc 4 to 10 rays per mm (medium). Occasionally rays more than 10 per mm (abundant). Ray height more than 1 mm. Occasionally larger rays more than 4 seriate. Occasionally sheath cells. Body ray cells procumbent with over 4 rows of upright and/or square marginal cel Septate fibers present. Fibers very thin walled. Fibers with simple to minutely bordered pits.


Cites Status


General Wood Description


The wood has a leathery or lemon odor and greasy nature.


The sapwood varies in color from straw to yellow. The heartwood is yellow-brown.


This species is reported to have straight grain.


The wood is typically fine in texture.


It is reported to be moderate in luster.

Natural Durability

This timber is durable and can be used for exterior purposes. It is also reported to be resistant to termites but the sapwood is susceptible to Lyctus.

Natural durability index (1= Very high durability, 7=Vey low durability)


Resistance To Impregnation

The heartwood is reported to be extremely resistant to preservative treatment.

Total shrinkage Radial (Saturated to 0%MC) (%)


Drying Defects

Ease of Drying: Drying is slow. Air drying of 25 mm thick boards about 2 months. Drying Defects: Some tendency to warp and end split is reported. Kiln Schedules: Schedule recommended for Nyatoh.

Stiffness (MOE) 12%MC (kgf/cm²)


Compression parallel to fiber 12%MC (kgf/cm²)


Shear strength radial 12%MC (kgf/cm²)




Machining operations are rather difficult.




It is very difficult to nail, rendering pre-boring essential.


The wood is difficult to work but with care finishes smoothly to a lustrous surface.
