Description edit

Hibbertia stirlingii is a shrub that typically grows to a height of up to 60 cm (24 in) and has stiffly woody main stems and scaly foliage. The leaves are linear, mostly 7.5–19 mm (0.30–0.75 in) long and 1.2–2.0 mm (0.047–0.079 in) wide on a petiole 0.4–1.5 mm (0.016–0.059 in) long. The flowers are arranged at the end of branches or in leaf axils, each flower on a thread-like peduncle 12–19 mm (0.47–0.75 in) long, with linear to lance-shaped bracts at the base. The five sepals are joined at the base, the two outer sepal lobes 2.4–3.3 mm (0.094–0.130 in) long and 2.2–3.0 mm (0.087–0.118 in) wide, and the inner lobes 4.2–5.7 mm (0.17–0.22 in) long and 4.1–5.2 mm (0.16–0.20 in) wide. The five petals are egg-shaped with the narrower end towards the base, yellow, 7.2–9.6 mm (0.28–0.38 in) long and there are ten to twelve stamens arranged in groups around the two densely scaly carpels, each carpel with two ovules. Flowering occurs from January to June[2]
