Description
Daviesia acicularis is a wiry shrub that typically grows to a height of up to 1 m (3 ft 3 in) and has hairy foliage. The phyllodes are tapering linear to narrow elliptic, 10–65 mm (0.39–2.56 in) long and 0.5–10 mm (0.020–0.394 in) wide with the edges curved downwards or rolled under and a prominent mid-vein on the upper surface. The flowers are 5–7 mm (0.20–0.28 in) long and arranged singly on a peduncle 1–2 mm (0.039–0.079 in) long. The sepals are 3.5–4.5 mm (0.14–0.18 in) long and joined at the base. The standard petal is yellow to orange with dark red markings and 5–7 mm (0.20–0.28 in) long and the keel is dark red grading to pink near the base. Flowering occurs from August in the north to October in the south and the fruit is a triangular pod 6–9 mm (0.24–0.35 in) long.[2][3][4]
