Other Uses

Furniture  Wood

Agroforestry Uses: The flowers are very sweetly scented and very attractive to bees[904 ]. Other Uses The heartwood is rose-brown with irregular veins; it is clearly demarcated from the 5 - 10cm wide band of white sapwood. The texture is medium; the grain straight or interlocked, sometimes wavy. The wood is moderately heavy to heavy; hard to very hard; elastic; durable, being resistant to fungi, dry wood borers and termites. It seasons somewhat slowly, with only a slight risk of checking or distortio; once dry it is stable in service. It works well with ordinary tools; takes a good polish; nailing and screwing are good, but require pre-boring; gluing is correct. A beautiful and expensive timber usually reserved for first class end uses, it is used in construction, high class furniture and cabinet making, billiard cues, turnery, sculpture, musical instruments, panelling, flooring veneer etc[356 , 848 , 904 ].

Cultivation details

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 ]. The hollow internodes on the branches are inhabited by ants[904 ].
