Description
Daviesia teretifolia is a spreading, glabrous, glaucous shrub that typically grows to a height of up to 1.2 m (3 ft 11 in). Its phyllodes are tapering cylindrical, upwards-pointing, 17–47 mm (0.67–1.85 in) long, 1.5–2 mm (0.059–0.079 in) wide and sharply pointed. The flowers are arranged in a group of three or four in leaf axils on a peduncle 2–7.5 mm (0.079–0.295 in) long, the rachis 2–7 mm (0.079–0.276 in) long, each flower on a pedicel 8–15 mm (0.31–0.59 in) long. The sepals are 4.5–5.5 mm (0.18–0.22 in) long and joined at the base, the two upper lobes joined for most of their length and the lower three lobes triangular. The standard petal is elliptic with a notched centre, 7.5–8.5 mm (0.30–0.33 in) long, 7.0–9.5 mm (0.28–0.37 in) wide and yellow to orange with a dark red to black centre. The wings are 7–8 mm (0.28–0.31 in) long and maroon, the keel 7.5–8 mm (0.30–0.31 in) long and maroon. Flowering occurs from May to October and the fruit is an inflated, triangular pod 13–16 mm (0.51–0.63 in) long.[2][3]
