Terminalia australis is a South American species of large shrub or tree, which reaches up to 12 m in height and 40 cm in diameter. It inhabits the basins of the Paraná River and the Uruguay River around the Argentine Mesopotamia, Paraguay and Uruguay, and part of the Río de la Plata. Terminalia australis is a deciduous tree with a small crown; it can grow 4 - 12 metres tall. The crooked bole can be 20 - 50cm in diameter[549 , 625 ]. The tree yields a timber with specialized uses and so is often harvested from the wild. It is also planted along rivers to stabilize the banks.
