Persoonia acicularis is a shrub that typically grows to a height of 0.1–1.2 m (3.9 in – 3 ft 11.2 in) with young branchlets covered with greyish hairs. The leaves are linear, more or less cylindrical, 12–25 mm (0.47–0.98 in) long and 0.6–1 mm (0.024–0.039 in) wide and sharply pointed. Yellow, cylindrical flowers are borne in groups of up to eighty along up to 120 mm (4.7 in) of the stems, each flower 8.5–15.5 mm (0.33–0.61 in) long on a pedicel 3–10 mm (0.12–0.39 in) long.[2][3]

Taxonomy and naming

Persoonia acicularis was first formally described in 1868 by Ferdinand von Mueller in his book Fragmenta Phytographiae Australiae from specimens collected by Augustus Frederick Oldfield near the Murchison River.[4][5] The specific epithet, acicularis, is derived from Latin and means "needle-shaped".[6]

This persoonia grows in heath in near-coastal areas of Western Australia between Shark Bay and the Arrowsmith River in the Geraldton Sandplains and Yalgoo bioigeographic regions.[2][3]

Conservation status

Persoonia acicularis is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[3]
