Description

Persoonia dillwynioides is an erect, spreading shrub that typically grows to a height of 0.6–1.8 m (2 ft 0 in – 5 ft 11 in) with smooth, mottled grey bark and branchlets that are angular and densely hairy when young but become cylindrical and glabrous with age. The leaves are arranged alternately along the stems, linear, 10–20 mm (0.39–0.79 in) long and 0.7–1.3 mm (0.028–0.051 in) wide and more or less concave on the upper surface. The flowers are arranged singly or in groups of up to four along a rachis up to 3 mm (0.12 in) long, each flower on a pedicel 1.5–2.5 mm (0.059–0.098 in) long. The tepals are bright yellow, 10–12 mm (0.39–0.47 in) long and 1.3–1.5 mm (0.051–0.059 in) wide and the anthers are bright yellow. Flowering occurs from November to December and the fruit is an oval drupe 7–10.5 mm (0.28–0.41 in) long and 4–5 mm (0.16–0.20 in) wide.[2][3][4][5]
