Pseudanthus ovalifolius is a spreading to compact, wiry monoecious shrub that typically grows to a height of 30 cm (12 in) and has glabrous branchlets.

The flowers are arranged singly in leaf axils, but sometimes appear clustered on the ends of branches with egg-shaped bracts 1.0–1.5 mm (0.039–0.059 in) long at the base.

[8] This species of shrub grows on rocky hillsides in heath, shrubland and mallee in scattered locations from near Eden in New South Wales, in the Grampians, near Bendigo and Ballarat in Victoria, and on Cape Barren and Flinders Islands in Tasmania.

The main threats to the species include land clearing, grazing by domestic stock and feral goats, and inappropriate fire regimes.
