Description

Pultenaea pinifolia is an erect shrub that typically grows to a height of 1–3 m (3 ft 3 in – 9 ft 10 in). The leaves are pine-like, 20–35 mm (0.79–1.38 in) long and 0.7–1 mm (0.028–0.039 in) wide with stipules 1.5–2 mm (0.059–0.079 in) long at the base. The flowers are yellow-orange with orange marks, each flower on a pedicel 3.5–4.5 mm (0.14–0.18 in) long. The sepals are hairy and 6.5–7 mm (0.26–0.28 in) long with hairy bracteoles 5–6.5 mm (0.20–0.26 in) long at the base. The standard petal is 10–11 mm (0.39–0.43 in) long, the wings 9.0–9.5 mm (0.35–0.37 in) long and the keel 9–10 mm (0.35–0.39 in) long. Flowering occurs from October to November and the fruit is a pod 10–11 mm (0.39–0.43 in) long.^[2]
