Acacia jamesiana is a tree or shrub belonging to the genus Acacia and the subgenus Juliflorae that is endemic central parts of western Australia.


The tree or shrub typically grows to a height of 1.5 to 6 metres (5 to 20 ft) that has silvery sericeous branchlets and resinous new shoots. Like most species of Acacia it has phyllodes rather than true leaves. The evergreen, ascending to suberect phyllodes are often linear-tetragonous in shape with a rhombic cross section. They are rigid with a pungent point and 8 to 22 cm (3.1 to 8.7 in) in length and 1 to 1.5 mm (0.039 to 0.059 in) wide. It blooms from May to November producing yellow flowers. The simple inflorescences occur singly in the axils and have obloid to shortly cylindrical flower-heads that are 9 to 12 mm (0.35 to 0.47 in) in length and 6 to 8 mm (0.24 to 0.31 in) wide and densely packed with golden flowers. Following flowering cartilaginous to subwoody seed pods form that have a linear shape with straight sides with a length of up to 12 cm (4.7 in) and 4 mm (0.16 in) wide and have finely longitudinal ridging. The glossy dark brown seeds inside are longitudinally arranged and have an elliptic-oblong shape with a length of 5 to 5.5 mm (0.20 to 0.22 in).


It is native to an area in the Mid West, Wheatbelt and Goldfields regions of Western Australia. It has a scattered distribution with the bulk of the population found from around Yalgoo in the west to the Carnarvon Range in the north east to around Leinster in the east. Outlying populations are located in the Gibson and Great Victoria Deserts. It is often situated on sand dunes and plains growing in a variety of soil types usually as a part of tall open shrubland communities and it is often associated with spinifex.
