Hibbertia pustulata

Hibbertia pustulata is a small shrub that typically grows to a height of up to 15 cm (5.9 in) and has more or less glabrous foliage. The leaves are more or less linear, mostly 6.0–7.5 mm (0.24–0.30 in) long, 0.6–0.8 mm (0.024–0.031 in) wide on a petiole 0.2–0.6 mm (0.0079–0.0236 in) long and with the edges rolled under. The flowers are arranged singly on the ends of branches with a triangular bract 0.7–1.1 mm (0.028–0.043 in) long at the base. The five sepals are joined at the base, the outer sepal lobes 5.9–6.3 mm (0.23–0.25 in) long and 2.5–2.6 mm (0.098–0.102 in) wide, the inner sepal lobes 3.2–3.4 mm (0.13–0.13 in) wide. The five petals are yellow, egg-shaped with the narrower end towards the base with a notch at the tip, 7.6–9.3 mm (0.30–0.37 in) long and there are four stamens fused at the base on one side of the two carpels, each carpel with four to six ovules. Flowering mainly occurs from August to October.

This hibbertia grows in swampy heathland near creek lines and occurs in the Blue Mountains and Wollemi National Parks in central eastern New South Wales.
