Description
Zieria fraseri is a dense, bushy shrub which grows to a height of about. Its leaves are composed of three narrow elliptic to narrow egg-shaped leaflets with the middle leaflet long and wide and the others smaller. The leaf stalk is long. The upper surface of the leaves is glabrous while the lower surface is covered with a dense layer of branched hairs and has an obvious mid-vein. The flowers are white to pale pink and are arranged in groups of between three and twenty or more in leaf axils. The four sepal lobes are about long and hairy on the outside. The four petals are about long, wide and in common with other zierias, there are only four stamens. Flowering occurs in spring and is followed by fruit which is a glabrous follicle dotted with oil glands.Taxonomy and naming
Zieria fraseri was first formally described in 1848 by William Jackson Hooker in Thomas Mitchell's Journal of an Expedition into the Interior of Tropical Australia from a specimen collected on Mount Barney. Hooker did not give a reason for the specific epithet but the type specimen was collected by Charles Fraser.There are two subspecies:Zieria fraseri subsp. fraseri which has leaves which are longer than the groups of flowers;Zieria fraseri subsp. robusta Duretto and P.I.Forst. which has leaves which are shorter than the groups of flowers.
