Other Uses
The heartwood is light to dark brown; it is clearly demarcated from the yellow to yellowish brown sapwood. The texture is medium to coarse; the grain usually deeply interlocked, producing a pronounced roe figure; lustre is high. The heartwood is rated as moderately durable. The wood dries rather slowly, with a marked tendency to check and warp; once dry it is fairly stable in service. It is difficult to saw because of gumming of the saw teeth; blunting may be serious; it machines moderately well with good turning characteristics; it is difficult to plane to a smooth surface because of severe tearing of the grain. It is used traditionally for poles in the contruction of huts, and sometimes for purposes such as parquet flooring, decorative veneer, general construction and joinery where high durability is not required[
