Description
The shrub typically grows to a height of and has minni ritchi style bark and flattened and angular ribbed branchlets that are glabrous or sparsely hairy on ribs and are sometimes coated with a white powdery coating. Like most species of Acacia, it has phyllodes rather than true leaves. The evergreen phyllodes have a linear or linear-oblanceolate shape and can be either straight or curved. The glabrous, flexible, or semi-rigid phyllodes have a length of and a width of with an acute to acuminate apex and have three to seven raised nerves on each face.

The simple inflorescences are found in pairs in the axils and have cylindrical flower spikes with a length of and a diameter of and are densely packed with 50 to 97 golden-coloured flowers. After flowering golden to silver-coloured velvety seed pods form that have a linear shape and are straight to very slightly curved. The pods have a length of up to and a width of with obliquely arranged seeds inside. The glossy black seeds have a broadly elliptic shape and a length of with an apical aril.Taxonomy
