Description
editPultenaea barbata is a spindly, prostrate or spreading shrub that typically grows to a height of 0.25–1.0 cm (0.098–0.394 in) with glabrous stems. The leaves are cylindrical but with a groove along the upper surface, 3–17 mm (0.12–0.67 in) long and 0.5–1.0 mm (0.020–0.039 in) wide and hairy with stipules at the base. The flowers are yellow, red, orange or brown with spots and blotches of yellow, red or orange. Each flower is borne on a hairy pedicel 2.5–3 mm (0.098–0.118 in) long with hairy bracteoles about 4 mm (0.16 in) long at the base. The sepals are 5.5–7 mm (0.22–0.28 in) long and hairy. The standard petal is 6.5–8 mm (0.26–0.31 in) long, the wings 7–7.5 mm (0.28–0.30 in) long and the keel is yellow, 5–7 mm (0.20–0.28 in) long. Flowering occurs from September to December and the fruit is an oval pod.[2][3]
