Zieria tenuis

Zieria tenuis is an open, straggly shrub which grows to a height of 1.5 m (5 ft) and has wiry branches covered with soft hairs. The leaves are composed of three oblong to narrow elliptic leaflets, the central leaflet one 9–32 mm (0.4–1 in) long and 3–7 mm (0.1–0.3 in) wide. The leaves have a petiole 5–18 mm (0.2–0.7 in) long. The lower surface of the leaflets have raised veins and the upper surface is covered with minute, star-like hairs. The flowers are arranged in groups of nine to twelve in leaf axils, the groups shorter than the leaves. The groups are on a stalk 8–18 mm (0.3–0.7 in) long and only about 0.5 mm (0.02 in) wide. The flowers are surrounded by scale-like bracts 1–3 mm (0.04–0.1 in) long which remain during flowering. The sepals are triangular, about 1–2.5 mm (0.04–0.1 in) long and 1 mm (0.04 in) wide and the four petals are white or pinkish, elliptic to egg-shaped, about 2 mm (0.08 in) long and 1 mm (0.04 in) wide with star-like hairs on both surfaces. There are four stamens. Flowering occurs between April and July and is followed by fruits which are smooth, glabrous capsules about 3 mm (0.1 in) long and 2 mm (0.08 in) wide.[2]

Zieria tenuis was first formally described in 2007 by Marco Duretto and Paul Forster from a specimen collected from Agate Creek near Forsayth and the description was published in Austrobaileya.[1] The specific epithet (tenuis) is a Latin word meaning "thin",[3] referring to the thin flower stalk.[2]

This zieria occurs near Forsayth and in the White Mountains National Park in the Desert Uplands and Einasleigh Uplands bioregions.[2]
