Boronia subulifolia

Boronia subulifolia is an erect, woody shrub that grows to a height of 0.25–1.2 m (0.8–4 ft) with more or less hairy younger stems. The leaves are pinnate with mostly five or seven leaflets and are 6–20 mm (0.2–0.8 in) long and 4–26 mm (0.2–1 in) wide in outline on a petiole 1–4 mm (0.04–0.2 in) long. The leaflets are linear to lance-shaped, 2.5–15 mm (0.1–0.6 in) long and 0.5–1 mm (0.02–0.04 in) wide. The flowers are light to deep pink and are usually arranged singly in leaf axils or on the ends of branches on a pedicel up to 1 mm (0.04 in) long. The four sepals are narrow triangular, 2.5–4 mm (0.1–0.2 in) long, 1–2 mm (0.04–0.08 in) wide and hairy on the lower side. The four petals are 5–8 mm (0.20–0.31 in) long and are slightly hairy. The stigma is about the same width as the style. Flowering occurs from September to January and the fruit is a mostly glabrous capsule 3–4.5 mm (0.12–0.18 in) long and 1.5–2.5 mm (0.06–0.1 in) wide.[2][3]

Boronia subulifolia was first formally described in 1928 by Edwin Cheel and the description was published in Journal and Proceedings of the Royal Society of New South Wales.[4][5] The specific epithet (subulifolia) is derived from Latin word subula meaning "an awl"[6]^:113 and folium meaning "a leaf",[6]^:466 referring to the finely pointed leaflets.[7]

Boronia subulifolia grows in heath and woodland on rocky sandstone, mainly in the Budawang Range.[2]
