Description
Daviesia longifolia is a bushy, many-stemmed shrub, typically 30–70 cm (12–28 in) high and about 1–3 m (3 ft 3 in – 9 ft 10 in) wide with weak, tangled branchlets. Its phyllodes are scattered, erect, cylindrical, snaking or curved, up to 250 mm (9.8 in) long and 1–10 mm (0.039–0.394 in) wide with six or more parallel ribs. The flowers are arranged in racemes of four to fifteen in leaf axils on a peduncle usually 10–17 mm (0.39–0.67 in) long, the rachis mostly 6–28 mm (0.24–1.10 in) long. The sepals are 3–4 mm (0.12–0.16 in) long and joined at the base, the upper two lobes joined for most of their length and the lower three about 0.5 mm (0.020 in) long. The standard petal is egg-shaped with a notch at the tip, 6.5–9 mm (0.26–0.35 in) long, yellow and dark red with an oblong yellow mark at the centre. The wings are 6.5–8 mm (0.26–0.31 in) long and dark red, and the keel 4.5–6.0 mm (0.18–0.24 in) long and deep red. Flowering occurs between August and December and the fruit is a flattened triangular pod 7–12 mm (0.28–0.47 in) long.[2][3]
