Summary
Swartzia bannia is a shrub or tree commonly found in Northern South America. Its bole has no buttress and can be branchless for up to 10 m. It has a symbiotic relationship with certain soil bacteria that form nodules on the roots and fix atmospheric nitrogen. It is not edible but its bark can be boiled with water as relief from diarrhea. The wood is of high quality - in fact known as one of the most dense and strongest wood. It is highly resistant to termites attack and shock.

Wood
Other Uses: The heartwood is deep purple-brown, almost black; it is sharply demarcated from the yellow to light yellow-buff sapwood which is less than 25mm wide. The texture is very fine; moderately lustrous; grain interlocked, producing a prominent striped figure[341 ]. The wood is one of the densest and strongest known. It has outstanding hardness, compression parallel to the grain and shearing characteristics. It is difficult to saw and hard to work because of its extremely high density; very smooth surfaces are obtainable in sawing or planing; it bores cleanly and turns well; takes a high polish; pre-boring is essential for nailing and screwing. Very resistant to termites but liable to marine borer attack. Wearing characteristics are excellent it is highly resistant to shock[341 ].
