A small tree 3-10 m high and spreading 3-5 m across. It normally has several stems. The bark is dark and fibrous. The leaves (phyllodes) are 6-15 cm long by 0.5-3 cm wide. They are flat and stiff. They are curved, leathery and with a bluish bloom. They have one prominent vein and a large gland at the base of the leaf. The edge of the leaf is prominent. The flower heads are balls. They occur singly or in pairs. They are bright yellow. The pods are 3-10 cm long by 1-1.5 cm across. They are flat, leathery and with a bluish bloom. They are waxy. They are raised over the seeds. The seeds are nearly round and 5 mm across. They are black to dark brown when ripe.
