The shrub has a slender habit and typically grows to a height of with glabrous branchlets. It has persistent juvenile bipinnate leaves. It has green oblanceolate or narrowly oblong-elliptic shaped phyllodes with a length of and a width of .[2] When it blooms it produces simple inflorescences of spherical flower-heads containing 20 to 35 cream to pale yellow coloured flowers.

It is scattered over eight Local Government Areas with an estimated total area of of which less than is inhabited by the plant. It has an estimated total population of between 1,000 and 2,500 plants inhabiting approximately 26 individual locations. The highly fragmented distribution is a result of habitat destruction and clearing, mostly from urban development pressures.[1]
