• Grows to 30m high on good sites.
• Log diameters of 1m.
• Bole (trunk) is straight and relatively short with steep, plank-like buttresses reaching 1.8m.
• Crown is a dense, deep, dome.

• Ranges from Thailand to Papua New Guinea and the Solomon Islands.
• Common in lowland forest and on ridges.

Colour

• Heartwood from pink-brown to red-brown.
• Sapwood is distinctly lighter, white to pink-brown in a 25mm wide band.

Grain

• Grain is straight or slightly interlocked.
• Texture is moderately coarse.

Construction

• Light construction, weatherboards, shingles.

Decorative

• Furniture, mouldings, joinery, plywood veneer, wall panelling, louvres and shutters.

Others

• Crates, fruit cases.
• Canoe planks and paddles (Solomon Islands, Papua New Guinea).

• Density: 555 kg/m³ at 12% moisture content; about 1.8m³ of seasoned, sawn timber per tonne.
• Strength groups: S6 unseasoned, SD6 seasoned.
• Stress grades: F4, F5, F7, F8 (unseasoned), F7, F8, F11, F14 (seasoned), when visually stress-graded according to AS 2082—2000: Timber—Hardwood—Visually stress-graded hardwood for structural purposes.
• Joint groups: J4 unseasoned, JD4 seasoned.
• Shrinkage to 12% MC: 6.9% (tangential), 2.9% (radial).
• Unit shrinkage: 0.28% (tangential), 0.21% (radial)—these values apply to timber reconditioned after seasoning.
• Durability above-ground: Class 3 (life expectancy 7–15 years).
• Durability in-ground: Class 3 (life expectancy 5–15 years).
• Lyctine susceptibility: untreated sapwood susceptible to lyctine borer attack.
• Termite resistance: not resistant.
• Preservation: difficult to impregnate with preservatives; results are unsatisfactory.
• Seasoning: slight collapse and some twisting may occur; use weights to minimise distortion; 25–50mm stock will kiln dry relatively easily to 12% moisture content.
• Hardness: soft (rated 5 on a 6-class scale) to indent and work with hand tools.
• Machining: not easy to saw, despite its medium density; machines to a smooth surface.
• Fixing: no difficulty using standard fittings and fastenings.
• Gluing: satisfactorily bonds using standard procedures.
• Finishing: seasoned timber surfaces will readily accept stain, polish, or paint.

• Zonate vessel: arrangements occur in some specimens.
• Burning splinter test: match-size splinter burns to white ash.
