Acacia gibsonii, commonly known as Gibson's wattle, is a shrub belonging to the genus Acacia and the subgenus Juliflorae.
The low, spreading shrub usually grows to a height of and a width of approximately and has a somewhat straggly habit. The terete branchlets are a reddish brown colour that age to a light grey colour. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen phyllodes have an oblong to oblong-elliptic that can be somewhat sigmoid, they have a length of and a width of . The phyllodes are glabrous with minute, red to brown coloured trichomes with three prominent longitudinal nerves. It blooms from September to October producing short cylindrical flower-spikes that are in length and quite densely flowered. Following flowering in around December tightly coiled seed pods form that are around and wide and are brown in colour with a thinly coriaceous texture.
It is native to a small area in the Goldfields-Esperance region of Western Australia to the south of the Norseman–Hyden Road where it is reasonably common within the restricted locale.[1] It is usually situated on gentle rocky slopes where it grows in skeletal red-loamy soils over greenstone base rocks in shrubland communities that are dominated by Allocasuarina campestris, Allocasuarina globosa and Calothamnus quadrifidus.[1]
