• Small tree, grows to 10–15m high.
• Stem is 15–25cm diameter.
• Stem and branches are often fluted.
• Bark is dark and sheds in curly flakes.

• Found in coastal and subcoastal parts of Central Queensland from near Eidsvold, north to southeast of Mt Garnet.

Colour

• Heartwood is deep red-brown to dark brown.
• Sapwood is cream to white.

Grain

• Grain is straight.
• If present, interlocked or wavy grain gives a ‘ring’ feature to polished surfaces.
• Texture is very fine and even.

Engineering and construction

• Used extensively, in the past, for fence posts.
• Not generally available in sizes suitable for engineered uses, even though strong enough—more suited to uses listed below.

Decorative

• Fancy turnery, walking sticks, ‘ringed’ timber especially prized.

Others

• Resonating parts of xylophones.
• Fingerboards and chin rests for violins (a substitute for ebony).
• Straight-grained timber may be used for sporting goods.
• Future potential for use in ‘small-volume, high-value’ niche markets.

• Density: 1280kg/m³ at 12% moisture content; about 0.75m³ of seasoned sawn timber per tonne.
• Strength groups: (S1) unseasoned, (SD1) seasoned (brackets indicate provisional value).
• Stress grades: F14, F17, F22, F27 (unseasoned); F22, F27, F34 (seasoned) when visually stress-graded according to AS 2082—2000: Timber—Hardwood—Visually stress-graded hardwood for structural purposes.
• Joint groups: JD1 seasoned.
• Shrinkage to 12% moisture content: not available.
• Unit shrinkage: not available.
• Durability above-ground: Class 1 (life expectancy more than 40 years).
• Durability in-ground: Class 1 (life expectancy more than 25 years).
• Lyctine susceptibility: untreated sapwood susceptible to lyctid borer attack.
• Termite resistance: not resistant.
• Preservation: sapwood readily impregnates with preservative but penetration of heartwood is negligible using available commercial processes.
• Seasoning: dries slowly with little degrade.
• Hardness: very hard (rated 1 on a 6-class scale) to indent and work with hand tools.
• Machining: using appropriate tooling and feed speeds, spear wattle dresses and machines well, resulting in a fine polish.
• Fixing: moderately fissile, be careful using standard fittings and fastenings.
• Gluing: as with most high-density species, machine and prepare surface immediately before gluing.
• Finishing: readily accepts paint, stain and polish.

General characteristics

• Sapwood: cream, distinct from heartwood.
• Heartwood: deep red-brown to dark brown.

Wood structure

• Vessels: solitary; small, indistinct to the naked eye; moderately numerous (4–12 per mm²).
• Vessel lines: fine, indistinct.
• Parenchyma (soft tissue):indistinct under a lens.
• Rays: fine, barely visible with a lens.

Other features

• Burning splinter test: match-size splinter burns slowly with a small, steady flame; embers glow for a long time, leaving a charcoal tip.
