Description
Boronia thujona is a glabrous shrub or small tree that grows to a height of 1–4 m (3–10 ft) with two grooves between the leaf bases on the smaller stems. It has aromatic, pinnate leaves with between three and fifteen leaflets. The leaf is 30–80 mm (1–3 in) long and 23–70 mm (0.9–3 in) wide in outline with a petiole 10–15 mm (0.4–0.6 in) long. The end leaflet is narrow elliptic in shape, 5–25 mm (0.2–1 in) long and 1–4 mm (0.04–0.2 in) wide and the side leaflets are similar but usually longer. The flowers are bright pink and are arranged in pairs or groups of up to six in leaf axils, each flower on a pedicel 5–15 mm (0.2–0.6 in) long. The four sepals are triangular, 0.5–1.5 mm (0.02–0.06 in) long, 0.5–1 mm (0.02–0.04 in) wide. The four petals are 5–10 mm (0.2–0.4 in) long with a hairy lower surface and a small point on the tip. The eight stamens have hairy filaments. The stigma is about the same width as the style. Flowering occurs from August to November and the fruit is a glabrous capsule 3–4 mm (0.12–0.16 in) long and 2–2.5 mm (0.08–0.1 in) wide.[2][3]
