Description

Persoonia brachystylis is a shrub that typically grows to a height of 1–1.5 m (3 ft 3 in–4 ft 11 in) with mottled grey bark and branchlets that are densely hairy when young. The leaves are narrow spatula-shaped to linear or lance-shaped, 45–120 mm (1.8–4.7 in) long and 2–10 mm (0.079–0.394 in) wide. The flowers are cylindrical and arranged in groups of ten to twenty, each flower on a pedicel 7–15 mm (0.28–0.59 in) long. The tepals are bright yellow, 10–13 mm (0.39–0.51 in) long and 1.5–2.5 mm (0.059–0.098 in) wide, the anthers white. Flowering occurs from November to December or January and the fruit is a oval drupe 10–12 mm (0.39–0.47 in) long and 6–7 mm (0.24–0.28 in) wide.[2][3][4][5]

Taxonomy

Persoonia brachystylis 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.[6][7]

Distribution and habitat

This geebung is restricted to the Kalbarri National Park where it grows in low heath on sandplains, often over laterite.[3][2]
