Known Hazards
Although we have no specific information for this species, the seeds of several other members of this genus contain the amino acid derivative djenkolic acid. Ingestion of seed containing this substance can cause the formation of sharp needle-like crystals of djenkolic acid in the kidney or urinary tract. In severe cases, crystals of djenkolic acid have been found in urine. Indeed, people who are suffering from djenkolism show similar symptoms to those suffering from kidney or urinary stones, a condition for which it has been frequently mistaken.
Distribution
It is a tropical plant. It grows in rainforest and swamp forest. It grows up to 1,700 m above sea level.
Where It Grows

Cultivation
A plant mainly of the moist, lowland tropics, where it also extends to elevations of 1,700 metres. Trees can flower and fruit all year round. 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.
Other Uses
The leaves and bark are sources of tannins. The leaves are used for colouring rattan. The leaves and bark are used to stain cloth black.
