It is a monoecious shrub with crowded, linear to narrowly egg-shaped leaves and creamy white male flowers and inconspicuous female arranged singly in upper leaf axils, but appearing clustered on the ends of branches.

Pseudanthus pimeleoides is a compact shrub that typically grows to a height of up to 60 cm (24 in) and has many glabrous branchlets.

The flowers are arranged singly in upper leaf axils with bracts 1.0–1.3 mm (0.039–0.051 in) long at the base, but appear to be clustered on the ends of branches.

[2][3] Pseudanthus pimeleoides was first formally described in 1827 by Kurt Polycarp Joachim Sprengel in Systema Vegetabilium from an unpublished description by August Siebert.

[6] Pseudanthus pimeleoides grows in sandy soil in moist gullies From Colo Heights to Bargo, with a few records from the upper Hunter Valley, in the Sydney region of New South Wales.
