Description
Persoonia hakeiformis is an erect or spreading to low-lying shrub that typically grows to a height of 0.3–1.8 m with smooth, mottled grey bark, flaky near the base, and branchlets that are hairy when young. The leaves are arranged alternately along the stems, linear, 15–50 mm long and 0.8–1.4 mm wide and grooved on the lower surface. The flowers are arranged singly or in groups of up to sixty along a rachis up to 100 mm long, each flower on a pedicel 3–7 mm long. The tepals are bright yellow, 8–12 mm long, the lowest tepal deeply sac-like with its anther fused to it. Flowering occurs from November to January and the fruit is a smooth drupe 8–13 mm long and 5–6 mm wide.

Taxonomy
Persoonia hakeiformis was first formally described in 1856 by Carl Meissner in de Candolle's Prodromus Systematis Naturalis Regni Vegetabilis.
