Hibbertia sulcata is a species of flowering plant in the family Dilleniaceae and is only known from a single specimen collected in Arnhem Land in the Northern Territory.

It is a small, sprawling shrub with wiry branches, linear leaves and yellow flowers arranged singly or in pairs in leaf axils with 22 to 24 stamens arranged in groups around two densely scaly carpels.

Hibbertia sulcata is a shrub that typically grows to a height of up to 20 cm (7.9 in) and has wiry branches and scaly foliage.

[2] Hibbertia sulcata was first formally described in 2010 by Hellmut R. Toelken in the Journal of the Adelaide Botanic Gardens from a specimen collected in north-eastern Arnhem Land in 2002.

[2][3] The specific epithet (sulcata) means "furrowed", referring to the edges of the leaves.
