Description
editDaviesia discolor is a glabrous, multi-stemmed shrub that typically grows to a height of up to 2 m (6 ft 7 in). Its leaves are reduced to linear to elliptic, more or less sickle-shaped phyllodes 40–160 mm (1.6–6.3 in) long, 4–11 mm (0.16–0.43 in) wide and striated, the lower surface a paler shade of green. The flowers are arranged in one or two groups of three to eight on a peduncle 1.5–6 mm (0.059–0.236 in) long, the rachis 1–4 mm (0.039–0.157 in) long, each flower on a pedicel 1.5–3.5 mm (0.059–0.138 in) long with narrowly oblong bracts about 1 mm (0.039 in) long at the base. The sepals are 3.5–4.0 mm (0.14–0.16 in) long and joined at the base, the two upper lobes joined for part of their length and the lower three triangular. The standard is broadly egg-shaped, 5.5–6.0 mm (0.22–0.24 in) long, 6.5–7.25 mm (0.256–0.285 in) wide and yellow with a red base, the wings 5.5–6.0 mm (0.22–0.24 in) long and yellow with a dull red base, and the keel 4.5 mm (0.18 in) long and pale green with a dull red tip. Flowering occurs from August and October and the fruit is a flattened, triangular pod 7.0–8.5 mm (0.28–0.33 in) long.[2][3][4]
