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.

Description

The shrub is low, spreading and multi-stemmed. It typically grows to a height of 0.5 to 0.7 metres (2 to 2 ft).[1] 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 4 to 4.5 cm (1.6 to 1.8 in) and a width of 1.3 to 1.6 mm (0.051 to 0.063 in) and are coarsely pungent with three nerves per face but often with only the central nerve being obvious.[2] It blooms in August producing yellow flowers.[1] The simple inflorescences occur suingly in the axils with sessile spherical shaped flower-heads that have a diameter of 4.5 mm (0.18 in) 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 6.5 cm (2.6 in) in length and have a width of around 2 mm (0.079 in) 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 3.2 to 3.5 mm (0.13 to 0.14 in) with a conical aril that is about the same length as the seed.[2]
Distribution

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.[1] It is localised around the town of Bulla bulling found about 30 km (19 mi) to the west of Coolgardie where it is a part of open shrubland communities.[2]
