Zanthoxylum pinnatum, commonly known as yellow wood,[2] is a species of flowering plant of the family Rutaceae native to Lord Howe and Norfolk Islands. It is a tree with pinnate leaves, white male and female flowers arranged in groups in leaf axils, and spherical, purple follicles containing a single black seed.
Zanthoxylum pinnatum is a tree that typically grows to a height of 10 m (33 ft). Its leaves are pinnate, usually with four to nine oblong to egg-shaped, slightly curved leaflets, mostly 50–80 mm (2.0–3.1 in) long and 30–45 mm (1.2–1.8 in) wide. The flowers are arranged in small to large groups in leaf axils with separate male and female flowers, the four sepals egg-shaped and 0.5–1 mm (0.020–0.039 in) long, the four or five petals white, lance-shaped and 2.5–3 mm (0.098–0.118 in) long. Flowering occurs from February to March and the fruit is a spherical, purple follicle about 8 mm (0.31 in) long containing a single black seed.[2][3]
