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[
A cold water infusion of the rasped bark is used as a treatment for fevers[
The trees of many members of this genus yield a wood suitable for light construction, known in the trade as 'tachi'[
]. We do not have any specific information for the wood of this species, but a general description of tachi wood is as follows:-
The wood is light brown; it is clearly demarcated from the 3 - 6cm wide band of sapwood. The texture is medium; the grain straight or slightly interlocked. The wood is light to moderately heavy; soft to moderately hard; not very durable in one report[
], durable in another[
]. It seasons at a nornal rate with only a slight risk of distortion, but a high risk of checking; once dry it is poorly stable in service. It is fairly easy to work, but sawn surfaces can be somewhat fuzzy - stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but require pre-boring. The wood is used for purposes such as interior panelling and joinery, furniture components, light carpentry, crates and boxes[
