}} Zieria fraseri is a plant in the citrus family Rutaceae and is endemic to eastern Australia. It is a dense, bushy shrub with leaves composed of three leaflets, and white flowers with four petals and four stamens. It usually grows in rocky places on steep hills. DescriptionZieria fraseri is an dense, bushy shrub which grows to a height of about {{convert|2|m|ft|sigfig=1|abbr=on}}. Its leaves are composed of three narrow elliptic to narrow egg-shaped leaflets with the middle leaflet {{convert|6-35|mm|in|sigfig=1|abbr=on}} long and {{convert|2-8|mm|in|sigfig=1|abbr=on}} wide and the others smaller. The leaf stalk is {{convert|2-8|mm|in|sigfig=1|abbr=on}} 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 {{convert|2|mm|in|sigfig=1|abbr=on}} long and hairy on the outside. The four petals are about {{convert|5|mm|in|sigfig=1|abbr=on}} long, {{convert|1-4|mm|in|sigfig=1|abbr=on}} 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.[1][2]Taxonomy and namingZieria 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.[3] Hooker did not give a reason for the specific epithet (fraseri) but the type specimen was collected by Charles Fraser.[2]There are two subspecies:
Distribution and habitatThis zieria grows in forest on rocky ridges and near cliffs in the McPherson Range in New South Wales and the Scenic Rim in Queensland.[1][1] References1. ^1 2 {{cite web|title=Zieria fraseri|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Zieria~fraseri|publisher=Royal Botanic Garden Sydney: plantnet|accessdate=28 May 2017}} 2. ^1 {{cite journal|last1=Duretto|first1=Marco F.|last2=Forster|first2=Paul Irwin|title=A taxonomic revision of the genus Zieria Sm.
