Zieria chevalieri

Zieria chevalieri is a shrub 30–75 cm (12–30 in) tall, sparsely branched with scars from fallen leaves. Leaves are whorled and condensed at the end of branches in groups of 3 or 4, are 4–5 cm (1.6–2.0 in) long and 0.2 cm (0.079 in) wide with short, scattered hairs on the dorsal surface. The ventral surface is light green with dense hairs and a slightly prominent midrib. The margins are slightly recurved, the apex is pointed and the base is tapered into a slender petiole.

Flowers are borne on axillary inflorescences with 2–7 flowers each. Petals are white or slightly pink, 5 mm (0.20 in) long with very slight indumentum. The peduncle is 2 cm (0.79 in) long and the pedicel is 7 mm (0.28 in) long, covered with reddish hairs and with two narrow, triangular bracteoles at the base. The four sepals are fused at the base and covered in reddish hairs. The four stamens have hairy filaments and the ovary is globose with four lobes.

Fruit is a capsule with four subunits (often with 1–3 aborted), 6 mm (0.24 in) wide and 2.5 mm (0.098 in) long, opened by 2 valves which usually contain a single black, oblong seed, 1.5 mm (0.059 in) wide and 3 mm (0.12 in) long.

It is distinct in that its leaves are arranged in whorls of 3 or 4, whereas Australian Zieria species leaves are arranged oppositely and are almost always trifoliate.^[3]

Zieria chevalieri was first formally described in 1953 by Robert Virot in Mémoires du Muséum national d'histoire naturelle. Série B, Botanique. The specific epithet honours French botanist Auguste Chevalier.^[2][4]
