Coatesia

It is a small, evergreen tree with simple, elliptical to egg-shaped leaves, panicles of white flowers on the ends of branchlets or in leaf axils and fused follicles with one black seed in each follicle.

The flowers are arranged on the ends of branchlets or in upper leaf axils, in panicles 15–90 mm (0.59–3.54 in) long.

Flowering occurs from April to May and the fruit is oval, beaked and 8–9 mm (0.31–0.35 in) long with one glossy black seed in each of the two or three follicles.

[7][8][9] As of September 2021[update], Plants of the World Online treated the genus as a synonym of Geijera, but it is accepted in a 2021 classification of the family Rutaceae, and placed in the subfamily Zanthoxyloideae.

The species is only known from a few locations near Tweed Heads, Lismore and Wardell in New South Wales and is threatened by land clearing, weed invasion and grazing by domestic livestock.
