Description

Hibbertia diffusa is a prostrate to low-lying shrub that typically grows to a height of up to 30 cm (12 in) and usually has glabrous stems. The leaves are egg-shaped to lance-shaped with the narrower end towards the base, 4–30 mm (0.16–1.18 in) long and 3–9 mm (0.12–0.35 in) wide on a short petiole. The flowers are sessile and mostly arranged on the ends of branchlets,the five sepals 6–8 mm (0.24–0.31 in) long and the five bright yellow petals 7–10 mm (0.28–0.39 in) long. There are twenty to twenty-five stamens arranged in groups around the two or three glabrous carpels. Flowering occurs from September to November. [2] [3] [4]

Taxonomy

Hibbertia diffusa was first formally described in 1817 by Augustin Pyramus de Candolle in his Regni Vegetabilis Systema Naturale from an unpublished description by Robert Brown. [5] [6]

Distribution and habitat

Wedge guinea flower grows in open forest on the coast and ranges of south-eastern Queensland, New South Wales and far north-eastern Victoria. [2] [3]
