Hibbertia crinita is a spreading to low-lying shrub that typically grows to a height of 0.2–1.5 m (7.9 in – 4 ft 11.1 in), its leaves and branches densely hairy with both long silky and star-shaped hairs.

The flowers are arranged in leaf axils in cluster of up to seven on the ends of branchlets and are sessile, surrounded by leaf-like bracts up to 9 mm (0.35 in) long.

The petals are yellow, egg-shaped with the narrower end towards the base, 5.4–13.6 mm (0.21–0.54 in) long and there are eight to sixteen stamens on one side of the two velvety carpels.
