The Tree Zieria or Stinkwood is a small tree or sturdy shrub in the citrus family. A common plant found in eastern Australia. Zieria arborescens subsp. arborescens may grow to 10 metres in height, the habitat is the edges of rainforest or in tall moist eucalyptus forest. Either near the coast or on the adjacent mountain ranges.[1] The leaves and timber have an unpleasant scent, hence the common name.

Typical of this group, the leaf is compound, featuring three leaflets. Leaflets are between 5 and 9 cm long, and 6 to 15 mm wide, the leaf stem is 1.5 to 3 cm long. White flowers form on stalks which are shorter than the leaves. Petals are 4 to 5 mm long.

This plant first appeared in scientific literature in 1811 in the Botanical Magazine, published by the English taxonomist John Sims. The original specimen used was from Joseph Banks' collection in London.

Zieria arborescens subsp. decurrens is only recorded from near Jervis Bay, it grows in drier eucalyptus areas. It features ridged non-warty branches and more hairs on the young branchlets.
