Zieria
Zieria is a genus of plants in the family, Rutaceae. About sixty species have been formally described, all of which are endemic to Australia except for one species which is found in New Caledonia. They occur in all Australian states except Western Australia but the genus is under review and a number of species are yet to be described or the description published. Zierias are similar to the better known genus Boronia but can be distinguished by the number of stamens in the flowers. The name Zieria honours the Polish botanist John Zier. Description Plants in the genus Zieria are shrubs or small trees. The leaves are arranged in opposite pairs and are usually compound with three leaflets similar in shape but the middle leaflet slightly larger. The flowers are arranged in groups in the leaf axils and have four fused sepals and four petals alternating with the sepals. There are four stamens (eight in Boronia) and four carpels with their styles fused. The fruit have four lobes, each containing one or two seeds. Taxonomy and naming The genus Zieria was first formally described in 1798 by James Edward Smith and the description was published in Transactions of the Linnean
