|The bright yellow flowers of a bracatinga (Mimosa scabrella)|
The bracatinga was a very important source of wood for the Brazilian railroads. Due to this use, and its rapid growth, the species is often planted as a source of fuel. It is also used as a shade tree and for ornamentation. It has also be used for making paper, fence posts, and, interestingly enough, as a food source for goats. The flowers can also be used for honey production.
