Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally vessels exclusively solitary (over 90%). Tangential diameter of vessel lumina 150 to 200 micras (medium). Occasionally vessels with colored deposits. Brown-colored deposits in heartwood vessels. Occasionally white deposits in Paratracheal axial parenchyma scanty and/or vasicentric. Axial parenchyma aliform. Axial parenchyma confluent. Axial parenchyma storied. Prismatic crystals in chambered axial parenchyma cells and/or in fibers. Two cells per parenchyma strand. 4 to 10 rays per mm (medium). Rays storied. Rays 1 to 4 seriate. Homogeneous rays and/or sub-homogeneous rays (all ray cells procumbent). Non-septate fibers. Fibers with simple to minutely bordered pits.

General Wood Description
Color
The heartwood is reddish-brown, it is not clearly demarcated.
COLOR INDEX (1=Black, 7=Light yellow,white)

Grain
Slightly interlocked grain and variations of the slope are frequent, and could induce distortion during drying.
Texture
This species is usually reported to have a coarse texture.
Luster
The wood surface is low in luster.
Natural Durability
Durable to decay; this species can be utilized without preservative treatment for exterior joinery or similar uses. Sensible to termites attack.
Natural durability index (1= Very high durability, 7=Vey low durability)

Internal Growth Stresses
No growth stresses are reported in this species.
Resistance To Impregnation
Nearly impossible to treat with a too much low penetration of the preservative substances.

Drying Defects
Ease of Drying: Air seasoning is reported to be good but rather slow. Boards 15 mm thick take about 3.5 months to air dry from green condition to 15% moisture content. Drying Defects: Slight bowing, springing and splitting may occur. Kiln Schedules: Schedule proposed for Kedondong. Boards 25 mm thick take about 6 days to kiln dry from 50% to 10% moisture content.

Planing
Moderately easy; tools must be cautiously sharpened.
Moulding
Rather difficult; special tools are needed.
Turning
30
Boring
Rather difficult; special tools are needed.
Mortising
Rather difficult; special tools are needed.
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.
