Description

Hibbertia tomentosa is a spreading to low-lying shrublet that typically grows to a height of up to 50 cm (20 in) and has foliage covered with rosette-like hairs. The leaves are linear, mostly 4–12 mm (0.16–0.47 in) long, 1–3 mm (0.039–0.118 in) wide and sessile or on a petiole up to 0.3 mm (0.012 in) long. The flowers are arranged singly on the ends of short side branches on a thread-like peduncle 3.6–10.7 mm (0.14–0.42 in) long, with linear bracts 2.5–4 mm (0.098–0.157 in) long at the base. The five sepals are joined at the base, the three outer sepal lobes 4.0–4.5 mm (0.16–0.18 in) long and 1.7–1.9 mm (0.067–0.075 in) wide, and the inner lobes shorter but broader. The five petals are narrow egg-shaped with the narrower end towards the base, yellow, 2.8–5.7 mm (0.11–0.22 in) long with a divided tip. There are fourteen to twenty stamens arranged in bundles around two densely scaly carpels, each carpel with two ovules. Flowering occurs from January to June.[2]
