Description
editHibbertia virgata is an erect, rarely low-lying shrub that typically grows to a height of up to 1.5 m (4 ft 11 in), its branches sometimes covered with woolly hairs. The leaves are linear, often cylindrical or grooved, 5–25 mm (0.20–0.98 in) long, 0.5–3.2 mm (0.020–0.126 in) wide and sometimes covered with silky hairs. The flowers are usually arranged on the ends of short side shoots and are sessile with hairy bracts 1.2–3.5 mm (0.047–0.138 in) long at the base. The sepals are oblong to egg-shaped, 5.4–9.8 mm (0.21–0.39 in) long, the petals bright yellow, egg-shaped with the narrower end towards the base, 5.8–12.2 mm (0.23–0.48 in) long. There are ten to twelve stamens arranged around three glabrous carpels. Flowering occurs from August to December.[2][3][4][5]
