Dillwynia divaricata is a species of flowering plant in the family Fabaceae and is endemic to the south-west of Western Australia. It is an erect, spindly shrub with cylindrical, grooved leaves and yellow flowers with brownish markings.

Description[]

Dillwynia divaricata is an erect, spindly shrub with glabrous branches but hairy leaves 6–15 mm (0.24–0.59 in) long and 0.8–1 mm (0.031–0.039 in) wide. The flowers are sessile or on a hairy pedicel up to 0.5 mm (0.020 in) long with hairy bracteoles about 3 mm (0.12 in) long, but that fall off as the flower opens. The sepals are also hairy, 5–7 mm (0.20–0.28 in) long and the corolla mostly yellow with brownish spots and blotches. The standard petal is 7–9.6 mm (0.28–0.38 in) long, the wings 6.6–7.5 mm (0.26–0.30 in) long and the keel 5–7 mm (0.20–0.28 in) long. Flowering mainly occurs from February to May.[2]
