About

Acacia orthocarpa, also commonly known as Pilbara weeping wattle, needle-leaf wattle or straight-podded wattle, is a shrub or tree belonging to the genus Acacia and the subgenus Juliflorae that is endemic to tropical parts of northern Australia. The indigenous Nyangumarta peoples know it as yartupu.

It is native to central and northern parts of the Pilbara region including some of the islands in the Burrup Peninsula and the Dampier Archipelago as well as much of the Kimberley region of Western Australia and the range of the plant extends eastward into the southern part of top end and the central region of the Northern Territory and into Queensland to the Mount Isa, Galilee and Georgetown areas where it is found on rocky hills, along rocky creeks and on sandy flats growing in skeletal sandy or loamy soils as a part of savannah woodland and open Eucalyptus shrubland communities usually with an understorey of spinifex grasses.
