Other Uses: Freshly cut heartwood is generally chocolate brown, turning to a lighter brown when dry, and may occasionally be greyish brown or brown, often with dark gold-coloured stripes or narrow stripes of a lighter brown; it is clearly demarcated from the narrow band of greyish or pinkish gray sapwood[ 378 ]. The grain is straight to slightly interlocked or sometimes slightly wavy; the texture is coarse to very coarse; the lustre is high and golden in the proper light, often with a waxy appearance; no distinctive odour or taste is present[ 378 ]. The wood is very hard, heavy, tough, strong and generally considered to be moderately resistant to decay, although tests at Yale University indicate the wood is very durable in resistance to both white-rot and brown-rot fungus[ 378 ]. The wood is moderately difficult to work; it saws rather easily, but is somewhat difficult to plane because of its frequently roey grain, which when present requires considerable sanding; it turns well; has high screw-holding power; and takes wax or polish satisfactorily if a filler is first applied[ 378 ]. It is used for heavy construction, boatbuilding, house framing, flooring, furniture, and turnery. The timber's recognized beauty should promote its extensive use for furniture, cabinetwork, marine construction in non-teredo waters, and other similar uses in the countries of origin and on the export market. Its very good strength properties also suggest its use for tool handles and agricultural tools and vehicles[ 378 ].

Cultivation details
Succeeds in full sun to dappled shade[ 420 ]. Prefers a well-drained soil[ 420 ]. Established plants are drought tolerant[ 420 ]. Newly planted young trees usually grow away moderately quickly[ 420 ]. This species has a symbiotic relationship with certain soil bacteria; these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[ 755 ].
