Pseudanthus pauciflorus is a species of flowering plant in the family Picrodendraceae and is endemic to eastern Australia.

Pseudanthus pauciflorus is a compact, monoecious shrub that typically grows to a height of up to 60 cm (24 in) and has upright to erect stems.

The flowers are arranged singly in upper leaf axils with bracts 1–3 mm (0.039–0.118 in) long at the base, but appear to be clustered on the ends of branches.

[2] In the same journal, Halford and Henderson described two subspecies of P. pauciflorus, and the names are accepted by the Australian Plant Census: Subspecies arenicola grows in heath and open forest in the Blackdown Tableland National Park and Robinson Gorge in the Expedition Range.

Subspecies pauciflorus grows in heath, shrubland and open forest in rocky places from near Rathdowney in south-eastern Queensland to Port Macquarie and as far west as Torrington in north-eastern New South Wales.
