Acacia epedunculata is a shrub belonging to the genus Acacia and the subgenus Juliflorae that is endemic to a very small area in arid parts of western Australia.
The shrub is low, spreading and multi-stemmed. It typically grows to a height of 0.5to. The branchlets have glabrous and resinous ribs with silky haired new shoots in between. Like most species of Acacia it has phyllodes rather than true leaves. The grey-green to silvery light green coloured phyllodes are substraight and shallowly incurved with a flat to compressed-rhombic shape. The phyllodes have a length of and a width of and are coarsely pungent with three nerves per face but often with only the central nerve being obvious.[1] It blooms in August producing yellow flowers. The simple inflorescences occur suingly in the axils with sessile spherical shaped flower-heads that have a diameter of and contain 20 golden coloured flowers. Following flowering thinly-crustaceous seed pods form that have a linear shape but are slightly constricted between each of the quite widely spaced seeds. The pods are up to in length and have a width of around and have pale margins and small silvery hairs on the dark brown faces. the glossy mottled brown seeds inside have a narrowly elliptic shape with a length of with a conical aril that is about the same length as the seed.[1]
It is native to an area in the Goldfields-Esperance region of Western Australia where it is commonly situated on sand-plains growing in yellow sandy soils. It is localised around the town of Bulla bulling found about to the west of Coolgardie where it is a part of open shrubland communities.[1]
