Boronia filifolia, commonly known as the slender boronia, [2] is a plant in the citrus family Rutaceae and is endemic to south-eastern Australia. It is a slender shrub with simple or pinnate leaves and pale to deep pink four-petalled flowers.
Boronia filifolia is a slender, glabrous shrub that grows to about 50 cm (20 in) high. Its leaves are simple or trifoliate on a petiole up to 2–8 mm (0.08–0.3 in) long. The simple leaves are linear to narrow egg-shaped, 3–30 mm (0.1–1 in) long and 1–1.5 mm (0.04–0.06 in) wide. The three leaflets on the pinnate leaves are similar to each other, 3–10 mm (0.1–0.4 in) long and 1–1.5 mm (0.04–0.06 in) wide. The flowers are pale to deep pink and are usually arranged singly in leaf axils near the end of the branches on a pedicel 2–13 mm (0.08–0.5 in) long. The four sepals are triangular to egg-shaped, 1–3 mm (0.04–0.1 in) long and 0.5–1.5 mm (0.02–0.06 in) wide with their bases overlapping. The four petals are 4–12 mm (0.2–0.5 in) long, 1.2–3 mm (0.05–0.1 in) wide and overlap at their bases. The stamens are covered with glandular hairs. Flowering occurs from July to February.

Boronia filifolia was first formally described in 1858 by Ferdinand von Mueller who published the description in Fragmenta phytographiae Australiae from a specimen collected near Encounter Bay. [5] [6] The specific epithet (filifolia) is derived from the Latin words filum meaning "thread" [7] : 797 and folia meaning "leaves" [7] : 466 referring to the very narrow leaflets. [3]

It is rare in Victoria where it is only known in the Little Desert National Park and part of the Big Desert near the border with South Australia, with a disjunct population near Portland. [2] [3]
