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)[1] 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.[2] It blooms from May to November producing yellow flowers.[1] 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).[2]
