Description

Hibbertia hooglandii is an erect or spreading, multi-stemmed shrub that typically grows to a height of up to 40 cm (16 in) and has hairy reddish-brown branchlets when young. The leaves are linear, 13–55 mm (0.51–2.17 in) long and 0.3–0.5 mm (0.012–0.020 in) wide with the edges rolled under. The flowers are arranged singly in leaf axils on a glabrous peduncle 15–35 mm (0.59–1.38 in) long with a linear bract 2.5–7 mm (0.098–0.276 in) long at the base of the sepals. The five sepals are joined at the base, 5–8 mm (0.20–0.31 in) long. The five petals are golden yellow, egg-shaped with the narrower end towards the base, 5.5–11 mm (0.22–0.43 in) long and 5–10 mm (0.20–0.39 in) wide. There are seventeen to twenty-five stamens on one side of the two hairy carpels with six to thirteen staminodes in rows outside the stamens. Each of the carpels is more or less spherical and contains two ovules.^[2][3]
