Cultivation Details

Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and therefore does not fix atmospheric nitrogen[].

Edible Uses

Fruit - raw[]. A powdery texture[]. The fruit is an oblong pod (legume), 5 - 15cm long and 3 -5cm wide, containing 3 - 4 large seeds which are surrounded by a dry, edible pulp[, ].

Medicinal

None known

Other Uses

The roots and trunk yield a pale yellow or red resin-like gum known commercially as 'South American copal'[, ]. The gum obtained from tapping the trunk is soft and considered to be of lower quality[] - it is used mainly for medicinal purposes[]. The best quality gum is quite old - it is found in hard lumps that have become buried in the soil at the base of a tree or at the site of a dead tree. A minor source of the gum (it is obtained mainly from Hymenaea courbaril), it can be used in making varnishes but also for incense and local medicines[, , ]. The copal is also used for patent leather, as an adhesive for crockery and in stains for tin ware[, ].

The heartwood can vary from purple-brown or orangey-brown to a red brown with slight veining; it is clearly demarcated from the 3 - 12cm wide band of sapwood. The texture is medium; the grain straight or interlocked; there are slight internal stresses. The wood is very heavy; very hard; elastic; durable, even in contact with the soil, being resistant to fungi, dry wood borers and termites. It seasons normally, with only a slight risk of checking and distortion; once dry it is moderately stable to stable in service. The wood has a fairly high blunting effect, stellite-tipped and tungsten carbide tools are recommended; nailing and screwing are good, but require pre-boring; gluing is correct for interior use only, but needs to be done with care because of the density of the wood. The wood has a wide range of applications, including for high class furniture, cabinet making, construction, heavy duty flooring, ship building, carving, turnery, tool handles etc[].

Propagation

Seed - it has a hard seedcoat and benefits from scarification before sowing to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Sow the treated seed in a partially shaded position in individual containers.
