Hibbertia cistifolia is a species of flowering plant in the family Dilleniaceae and is endemic to northern Australia. It is a prostrate to low-lying sub-shrub with trailing, wiry stems, hairy foliage, oblong to elliptic leaves and yellow flowers arranged in leaf axils, with forty to fifty-eight stamens arranged around the two carpels.

Description
Hibbertia cistifolia is a prostrate to low-lying sub-shrub that typically grows to a height of up to 30 cm, its stems wiry and the foliage covered with rosette-like hairs. The leaves are mostly oblong or elliptic to lance-shaped with the narrower end towards the base, 20–40 mm long and 5.0–12.5 mm wide on a petiole 0.2–2.4 mm long. The flowers are arranged singly in leaf axils on a wiry peduncle 25–35 mm long, with linear to lance-shaped bracts 3–4.5 mm long. The five sepals are joined at the base, the two outer sepal lobes 8.5–10.4 mm long and the inner lobes 6.4–7.2 mm long. The five petals are broadly egg-shaped with the narrower end towards the base, yellow, 8–15 mm long with a deep notch at the tip. There are forty to fifty-eight stamens arranged around the two carpels, each carpel with two ovules. Flowering occurs from December to June.

Taxonomy
Hibbertia cistifolia was first formally described in 1817 by Augustin Pyramus de Candolle in his Regni Vegetabilis Systema Naturale from an unpublished description by Robert Brown.
