Description

Dillwynia acicularis is an erect shrub that typically grows to a height of 1–3 m (3 ft 3 in – 9 ft 10 in) with hairy stems. The leaves are erect, narrow linear, sometimes triangular in cross-section, 10–35 mm (0.39–1.38 in) long with a longitudinal groove on the upper surface. The flowers are arranged in racemes on the ends of branchlets with leaves at the base, and hairy bracts and bracteoles about 1 mm (0.039 in) long. The sepals are 4–5 mm (0.16–0.20 in) long, and the standard petal is 7–9 mm (0.28–0.35 in) long and the keel is yellow with red markings.[2][3]

Dillwynia acicularis was first formally described in 1825 by Augustin Pyramus de Candolle in his Prodromus Systematis Naturalis Regni Vegetabilis.[4][5] The specific epithet (acicularis) means "needle-pointed".[6]
