Description
editDaviesia gracilis is an open, spreading, glabrous shrub that typically grows to a height of up to 50 cm (20 in), its phyllodes reduced to scales. The flowers are arranged in groups of three to five on a peduncle 1.0–1.5 mm (0.039–0.059 in) long, the rachis 0.5–3 mm (0.020–0.118 in) long, each flower on a pedicel 3–6 mm (0.12–0.24 in) long with oblong, overlapping bracts about 4 mm (0.16 in) long at the base. The sepals are about 3.0–3.5 mm (0.12–0.14 in) long and joined at the base. The standard petal is elliptic, 8–9 mm (0.31–0.35 in) long and orange-yellow with a thin maroon border, the wings about 7.0–7.5 mm (0.28–0.30 in) long and maroon, and the keel is 3.5–4.5 mm (0.14–0.18 in) long and maroon. Flowering occurs from July to October and the fruit is a flattened triangular pod 16–19 mm (0.63–0.75 in) long.[2][3]
