About Hibbertia diffusa R.Br.
Hibbertia diffusa R.Br., commonly called wedge guinea flower, is a prostrate to low-lying shrub. It typically grows up to 30 centimetres (12 inches) in height, and usually has hairless (glabrous) stems. Its leaves are egg-shaped to lance-shaped, with the narrower end positioned toward the base, and measure 4–30 mm (0.16–1.18 in) long and 3–9 mm (0.12–0.35 in) wide, borne on a short petiole. The flowers are stalkless (sessile), and are mostly arranged on the ends of branchlets. Each flower has five sepals 6–8 mm (0.24–0.31 in) long, and five bright yellow petals 7–10 mm (0.28–0.39 in) long. Between twenty and twenty-five stamens are arranged in groups around two or three hairless carpels. Flowering takes place from September to November. This species grows in open forest on the coast and ranges of south-eastern Queensland, New South Wales, and far north-eastern Victoria.
