Endangered in the Sarawak region. Its status is currently listed as unknown because of inadequate information in Thailand, Brunei, Indonesia, Singapore, Sabah, and Sumatra Distribution Overview Thailand, Indonesia (Sumatra), the Riau Archipelago, Bangka, Belitung, Borneo Peninsular Malaysia, Sarawak and Sabah. Found in lowland forest, peat and freshwater swamp, occurring from sea-level up to 600 m. Heartwood Color
Freshly-Cut heartwood is pink to brick red. Upon exposure, it matures into an orange-red or red-brown color, with numerous yellow lines or streaks. They are abnormal sections lacking vessels may be a source of mechanical weakness. Sapwood Color

Natural Growth Defects
Natural Durability
The timber is naturally resistant to decay in the temperate zones but is susceptible to termite attack in the tropics Odor

Corrosive Properties
Kiln Schedules
Drying Defects
Drying defects are at a minimum in this species, but areas of abnormal tissue, which is occasionally present may cause severe splitting. Ease of Drying
The material dries fairly well and rapidly, but zones of abnormal tissue may cause severe splitting. Kiln Drying Rate
Tree Identification
Tree Size
The tree matures to heights of up to 180 feet (54 m), with trunk diameters of up to 72 inches (180 cm) or more above heavy buttresses. Boles are clear to heights of 80 to 90 feet (24 to 27 m). Comments Abrasive Material Content - The wood contains abnormal veins of rock-hard tissue which may interfere with machining operations Corrosive Properties - The wood is slightly acidic and may promote corrosion in some metals under moist conditions. Blunting Effect
Blunting effect on cutting tools varies but may be severe due to hardness and fibrous texture. Boring
Carving
Cutting Resistance
Sawing requires adequate power supply, but it is rated as satisfactory Mortising
Moulding
Movement in Service
Properly seasoned material is stable, and undergoes only minimal dimensional changes in response to changes in moisture content Nailing
Pre-Boring is recommended to prevent splitting when nailing close to edges. Planing
The material is reported to plane to yield fairly good surfaces, but it is affected by interlocked grain and fibrous texture. A 20 degree cutting angle is recommended. Resistance to Impregnation
Both heartwood and sapwood are reported to respond readily to preservative treatment. Resistance to Splitting
Response to Hand Tools
The wood is difficult to work with hand tools because it is hard and tough Routing & Recessing
Sanding
Turning
Veneering Qualities
Polishing
Staining
Staining properties are good after surface preparation. Strength Properties
