The timbers range in colour from pale brown, through pinkish-brown to a deep red brown. A common
feature is the white or pink desposits in the vessels sapwood is pale coloured between 25mm and
50mm wide but not sharply demarcated from the heartwood. Wood shavings will froth when shaken in
water due to the presence of saponin. The timber is usually straight grained but occasionally, slightly
interlocked. It has a moderately coarse texture. A slight flame-like figure is sometimes seen on back
sawn material and a ribbon or striped figure is evident on quarter sawn material where interlocked
grain occurs. It has a slight, natural lustre. The timber is non-siliceous. There is neither taste no odour.
Taun occurs in low-lying coastal and riverine areas from Sri Lanka through southeast Asia, Papua New
Guinea to the Solomons and Samoa.

F7, F8, F11, F14 (unseasoned), F11, F14, F17, F22 (seasoned), when visually stress graded in
accordance with AS2082-2000, ‘Visually stress-graded hardwood for structural purposes.’
Taun works easily with most machine and hand tools, but properties may vary with site and form.
Timber saws cleanly, producing fair to excellent surfaces. Peeling properties variable. Good quality
stock is suitable for face veneer in plywood. Species glues, screws and nails well, takes nice polish,
paints and stains satisfactorily. Shrinkage and ensity variable, steam-bending properties generally
good, moisutre movement low to medium. Heatwood impermeable, sapwood moderately resistant to
impregnation. Species susceptible to pinhole borer and marine borer attack, and brown-stain.
