Persoonia brevirhachis is a species of flowering plant in the family Proteaceae and is endemic to the south-west of Western Australia. It is an erect, often spreading shrub with smooth, compact bark, mostly narrow spatula-shaped to lance-shaped leaves with the narrower end towards the base and yellow to greenish yellow flowers borne singly or in pairs in leaf axils.
Persoonia brevirhachis is an erect to spreading shrub that typically grows to a height of 0.3–2 mm (0.012–0.079 in) with smooth, mottled grey bark and hairy branchlets. The leaves are narrow spatula-shaped to lance-shaped with the narrower end towards the base, 20–50 mm (0.79–1.97 in) long and 2.5–5.5 mm (0.098–0.217 in) wide. The flowers are arranged singly or in pairs in leaf axils on pedicels 1.5–5 mm (0.059–0.197 in) long. The tepals are yellow to greenish yellow, 6.5–9 mm (0.26–0.35 in) long and 1–1.5 mm (0.039–0.059 in) wide and hairy on the outside. Flowering occurs from August to October and the fruit is a smooth, oval drupe 4.5–5.5 mm (0.18–0.22 in) long and 2–2.5 mm (0.079–0.098 in) wide.[2][3][4][5]
