Description Of The Tree
Botanical Description
It is a medium-sized tree up to 35 m tall, occasionally only small trees. The bole is straight, fairly cylindrical, up to 60 cm in diameter, buttresses present.
Natural Habitat
Monocarpia occurs scattered in primary, lowland evergreen rain forest, up to 1,200 m of altitude.
Wood Identification
Anatomic Description Of Wood
Wood diffuse porous. Occasionally tangential diameter of vessel lumina 100 micras or less. Vessels per mm2 5 to 20. Helical thickenings in vessel elements present. Simple perforation plates. Vessel-ray pits similar to intervessel pits in size and shape. Interve Apotracheal axial parenchyma diffuse and/or diffuse in aggregates. Occasionally paratracheal axial parenchyma scanty and/or vasicentric. 3 to 4 cells per parenchyma strand. 5 to 8 cells per parenchyma strand. Axial parenchyma in narrow bands on lines up to 3 4 to 10 rays per mm (medium). Rays of two distinct sizes. Ray height more than 1 mm. Larger rays more than 4 seriate. Occasionally sheath cells. Body ray cells procumbent with mostly 2 to 4 rows of upright and/or square marginal cells (Kribs-II). Body ray cells Fibers with simple to minutely bordered pits.

Drying Defects
Ease of Drying: Kelat timber air dries slowly to very slowly. In Malaysia boards 15 mm thick are reported to dry in 5 months. Drying Defects: The timber is liable to end-splitting and checking. Kiln Schedules: Kiln drying requires a mild schedule. Pre-drying before kilning is advised to prevent serious degrade.

Workability
Rotary Veneer Cutting
Peeling should be done as soon as possible after felling. End splits in logs are the main problem in the manufacture of rotary veneer.
Sliced Veneer
Peeling should be done as soon as possible after felling. End splits in logs are the main problem in the manufacture of rotary veneer.
Machining
It works well in all processes.
Planing
Planing operations are reported to be easy, but the planed surfaces may not be perfectly smooth.
