Description
editPultenaea radiata is an erect, open shrub that typically grows to a height of 15–50 cm (5.9–19.7 in) and has hairy stems. The leaves are arranged in opposite pairs, linear to needle-shaped, 4.5–11 mm (0.18–0.43 in) long and 0.5–1 mm (0.020–0.039 in) wide with one or two grooves along the lower surface and stipules 1.5–2.6 mm (0.059–0.102 in) long at the base. The flowers are red and pinkish-purple, arranged in clusters with bracteoles 4.5–5.0 mm (0.18–0.20 in) long attached to the pedicel. The sepals are 7–9 mm (0.28–0.35 in) long, the standard petal 14–18 mm (0.55–0.71 in) long, the wings 9.5–11 mm (0.37–0.43 in) long and the keel 7.5–6.0 mm (0.30–0.24 in) long. Flowering occurs from September to October and the fruit is a flattened pod.[2]
Taxonomy and naming

Distribution
editThis pultenaea is found in the Jarrah Forest, Swan Coastal Plain and Warren biogeographic regions of south-western Western Australia.[2]
Conservation status
editPultenaea radiata is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[2]
