Description
Hibbertia circumdans is an erect shrub that typically grows to a height of 60 cm with glabrous branches. The leaves are linear to wedge-shaped or spatula-shaped, 5–12 mm long and 2–5 mm wide, folded lengthwise and with the edges curved downwards. The flowers are on the ends of short side shoots and are sessile with bracts about 2 mm long. The five sepals are egg-shaped, 5–6.5 mm long and the petals are spatula-shaped, 5.5–11 mm long and 6–11 mm wide. There are fifteen to thirty stamens arranged around three glabrous carpels. Flowering mostly occurs from August to November.

Taxonomy
Hibbertia circumdans was first formally described in 1990 by Barry Conn in the journal Muelleria from specimens collected by Ruurd Dirk Hoogland near Capertee in 1972. The specific epithet (circumdans) refers to the arrangement of the stamens around the carpels.

Distribution and habitat
This hibbertia grows in the shrub layer of woodland and forest between the Pilliga Scrub and Nadgee Nature Reserve in New South Wales.
