Acacia chrysocephala is a shrub belonging to the genus Acacia and the subgenus Phyllodineae.
The dense, compact and spiny shrub typically grows to a height of 0.2 to 0.6 metres (1 to 2 ft). It blooms from May to October and produces yellow flowers. [1] The inequilateral phyllodes have an obtriangular to shallowly obtriangular shape with a margin congruent with branchlet. The glabrous phyllodes are 3 to 12 millimetres (0.12 to 0.47 in) in length and 1.5 to 10 mm (0.06 to 0.39 in) and are commonly pungent. The simple inflorescences usually occur with one per axil forming globular flower heads with two to four flowers per head. Following flowering shallowly curved seed pods form with a length of up to 3 centimetres (1.18 in) and a width of 1.5 to 10 mm (0.06 to 0.39 in). The shiny brown longitudinally oblong seeds are 1.5 to 10 mm (0.06 to 0.39 in) long. [2]
