Description

Boronia suberosa is a shrub with weeping branches up to 50 cm (20 in). Its branches are covered with star-shaped hairs when young but become very corky with age. The leaves are simple, elliptic to lance-shaped, 7–20 mm (0.28–0.79 in) long and 3–11 mm (0.12–0.43 in) wide on a petiole up to 3 mm (0.12 in) long. The flowers are borne singly, on a peduncle 0.5–1 mm (0.02–0.04 in) long. The sepals are green, egg-shaped to triangular, 3–5 mm (0.12–0.20 in) long, 2–3 mm (0.08–0.1 in) wide and larger than the petals. The petals are white, 2.5–3 mm (0.098–0.12 in) long and both the sepals and petal enlarge as the fruit develops. Flowering occurs between February and May and the fruit is a more or less hairy capsule 3.5–5 mm (0.14–0.20 in) long and 2–2.5 mm (0.079–0.098 in) wide.[2][3][4]

Taxonomy and naming
