It is an erect, woody shrub with pinnate or bipinnate leaves and groups of up to three white to pale pink, pink four-petalled flowers arranged in leaf axils. DescriptionBoronia occidentalis is an erect, woody shrub that grows to a height of about {{convert|1|m|ft|sigfig=1|abbr=on}}. It has pinnate or bipinnate leaves with between three and seven leaflets. The leaf is {{convert|9-25|mm|in|sigfig=1|abbr=on}} long and {{convert|7-25|mm|in|sigfig=1|abbr=on}} wide in outlines, on a petiole {{convert|3-7|mm|in|sigfig=1|abbr=on}}. The end leaflet {{convert|1-4|mm|in|sigfig=1|abbr=on}} long and {{convert|0.5-1|mm|in|sigfig=1|abbr=on}} wide and the side leaflets are similar but longer. The flowers are white to pale pink and are arranged singly or in groups of up to three in leaf axils on a peduncle {{convert|0.5-2|mm|in|sigfig=1|abbr=on}} long. The four sepals are triangular, {{convert|1-2.5|mm|in|sigfig=1|abbr=on}} long and {{convert|0.5-2|mm|in|sigfig=1|abbr=on}} wide. The four petals are {{convert|2-3|mm|in|sigfig=1|abbr=on}} long. The eight stamens are hairy on their edges and the stigma is tiny, no wider than the style. Flowering mainly occurs from July to January and the fruit is a capsule {{convert|2-2.5|mm|in|sigfig=1|abbr=on}} long and about {{convert|1.5|mm|in|sigfig=1|abbr=on}} wide with the petals remaining.[1][2]Taxonomy and namingBoronia occidentalis was first formally described in 2003 by Marco F. Duretto from a specimen collected in the Wondul Range National Park and the description was published in Muelleria.[1][3] The specific epithet (occidentalis) is a Latin word meaning "western",[4] alluding to the fact that in most places, this species has a more westerly distribution than that of other boronias.[1]Distribution and habitatThe rock boronia is one of the most widespread boronias and is found between Mount Sturgeon near Hughenden in north Queensland and Dubbo in New South Wales. It mostly grows in woodland on sandstone or in sandy soil.[1][2] ConservationBoronia occidentalis is listed as "least concern" by the Queensland Government Department of Environment and Science.[5]References1. ^1 2 3 {{cite journal |last1=Duretto |first1=Marco F. |title=Notes on Boronia (Rutaceae) in eastern and northern Australia |journal=Muelleria |date=2003 |volume=17 |pages=36–40 |url=https://www.rbg.vic.gov.au/documents/Muelleria_17,_p19-135,_Duretto,_Notes_on_Boronia.pdf |accessdate=9 February 2019}} {{Taxonbar|from=Q4946277}}2. ^1 {{cite web |title=Boronia occidentalis |url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Boronia~occidentalis |publisher=Royal Botanic Garden Sydney |accessdate=9 February 2019}} 3. ^{{cite web|title=Boronia occidentalis|url= https://id.biodiversity.org.au/instance/apni/585013|publisher=APNI|accessdate=9 February 2019}} 4. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page = 807}} 5. ^{{cite web |title=Boronia occidentalis |url=https://wetlandinfo.des.qld.gov.au/wetlands/ecology/components/species/?boronia-occidentalis |publisher=Queensland Government Department of Environment and Science |accessdate=9 February 2019}} 5 : Boronia|Flora of New South Wales|Flora of Queensland|Plants described in 2003|Taxa named by Marco Duretto |
