Description
editHibbertia laurana is a shrub that typically grows to a height of up to 2–4 m (6 ft 7 in – 13 ft 1 in), its branches and leaves densely covered with rust-coloured hairs when young. The leaves are elliptic, 75–95 mm (3.0–3.7 in) long and 20–37 mm (0.79–1.46 in) wide on a petiole 8–12 mm (0.31–0.47 in) long, the edges of the leaves turned down or rolled under or with a few teeth. The upper surface of the leaves is slightly shiny and the lower surface is covered with white hairs. The flowers are borne in leaf axils in groups of three to five on peduncles 7–17 mm (0.28–0.67 in) long. There are egg-shaped or elliptic bracts 6–7 mm (0.24–0.28 in) long, the sepals are elliptic to egg-shaped with the narrower end towards the base, 1.3–1.7 mm (0.051–0.067 in) long and with rust-coloured hairs on the outside. The five petals are egg-shaped with the narrower end towards the base, yellow, 12–14 mm (0.47–0.55 in) long and with two lobes at the tip. There are thirty to fifty stamens fused at the base and arranged in rows on one side of the two hairy carpels, each carpel with two ovules.[2]
Taxonomy

Distribution and habitat
editThis hibbertia usually grows among sandstone outcrops and is common near Laura in far north Queensland.[2]
Conservation status
