Although we have seen no specific information for this species, the large seeds of many species in this genus are used for food. Usually cooked, they are rich in oil and have a flavour described by some as like peanuts[
]. The ellipsoid seed is 10 - 23mm long[
A fibre obtained from the bark is used to make rope[
]. Fairly strong, it has a tensile strength of 398 kilos per square centimetre[
]. Wetting decreases the strength by 23%[
A physical dormancy caused by the hard seed coat of the mature seeds of many species in this genus can be overcome by scarifying the seed. This is carried out by cutting away or abrading some of the seed coat to allow the ingress of water, though great care must be taken not to damage the embryo[
]. The aril surrounding the seed should also be removed - this is easiest when it has been softened through soaking in water[
]. The seeds germinate optimally at temperatures between 20 - 30°c. They can be sown in a nursery seedbed or in containers. A germination rate of about 95%, occurring within about 2 weeks can be expected if the seed has been properly treated[
