It is a sometimes straggly shrub with velvety leaves composed of three leaflets. In late autumn to spring there are clusters of small white to pinkish flowers with four petals and which appear to be unable to produce seeds. DescriptionZieria baeuerlenii is an open, spreading shrub which usually grows to a height of {{convert|0.8|m|ft|sigfig=1|abbr=on}} and has a velvety covering on its younger branches. The leaves are arranged in opposite pairs and are composed of three leaflets with the central one heart-shaped with the narrower end towards the base, {{convert|6-12|mm|in|sigfig=1|abbr=on}} long and {{convert|4-9|mm|in|sigfig=1|abbr=on}} wide with a stalk {{convert|1.5-2.5|mm|in|sigfig=1|abbr=on}} long. The other two leaflets are similar in shape but slightly smaller. Each leaflet has a velvety covering of hairs and has its edges rolled under.[1][2][3]Masses of small pinkish-white flowers about {{convert|8|mm|in|sigfig=1|abbr=on}} in diameter are arranged in clusters of between three and seven in leaf axils. The clusters have a stalk up to {{convert|10|mm|in|sigfig=1|abbr=on}} and are longer than the leaves. Four large green, leaf-like bracts surround each flower cluster. The sepals are triangular, about {{convert|2|mm|in|sigfig=1|abbr=on}} long and covered with velvety hairs. The four petals are broad lance-shaped, about {{convert|3|mm|in|sigfig=1|abbr=on}} long, overlap each other and have a layer of hairs on the outside. Flowering occurs from September to October but fruit have never been observed and evidence suggests that the species has lost its ability to reproduce sexually.[1][2][3] Taxonomy and namingBomaderry zieria was first formally described in 2002 by James Andrew Anderson from a specimen collected near Bomaderry Creek. The description was published in Australian Systematic Botany.[4][5] The specific epithet (baeuerlenii) honours the German-born plant collector Wilhelm Baeuerlen who moved to Australia in about 1883, lived in the Shoalhaven area and collected for Ferdinand von Mueller and Joseph Maiden.[6][7] Distribution and habitatZieria baeuerlenii is only known from an area of {{convert|0.5|km2|acre|sigfig=1|abbr=on}} near Bomaderry. In grows in soil derived from sandstone in forest, woodland and scrub.[1][2][3]EcologyFruit or seed of Bomaderry Zieria has not been observed and it is thought that the species has lost the ability to reproduce sexually and probably reproduces from suckers. It has the ability to regenerate after bushfire.[2][3] ConservationBomaderry zieria is listed as "Endangered" under the New South Wales Threatened Species Conservation Act and under the Commonwealth Government Environment Protection and Biodiversity Conservation Act 1999 (EPBC) Act. Some of the threats to the species are habitat damage due to illegal activities, weed invasion, grazing by rabbits and frequent fires.[2][3] References1. ^1 2 {{cite web|last1=Armstrong|first1=James Andrew|last2=Harden|first2=Gwen|title=Zieria baeuerlenii|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Zieria~baeuerlenii|publisher=Royal Botanic Garden Sydney: plantnet|accessdate=22 December 2016}} 2. ^1 2 3 4 {{cite web|title=Bombaderry Zieria - profile|url=http://www.environment.nsw.gov.au/threatenedSpeciesApp/profile.aspx?id=10850|publisher=Government of New South Wales Department of the Environment and Heritage|accessdate=6 November 2016}} 3. ^1 2 3 4 {{cite web|title=National recovery plan for the Bombaderry Zieria Zieria baeuerlenii|url=http://www.environment.gov.au/system/files/resources/9d0532f8-b28c-4eb1-8a68-4ae18f33b505/files/zieria-baeuerlenii-recovery-plan.pdf|publisher=Department of Environment, Climate Change and Water (NSW), 2010|accessdate=22 December 2016}} 4. ^1 {{cite web|title=Zieria baeuerlenii|url= https://id.biodiversity.org.au/instance/apni/579540|publisher=APNI|accessdate=22 December 2016}} 5. ^{{cite journal|last1=Armstrong|first1=Jim A.|title=The genus Zieria (Rutaceae): a systematic and evolutionary study|journal=Australian Systematic Botany|date=2002|volume=15|issue=3|pages=277–463|doi=10.1071/SB00040}} 6. ^{{cite book|last1=Quattrocchi|first1=Umberto|title=CRC world dictionary of plant names : common names, scientific names, eponyms, synonyms, and etymology|date=1999|publisher=CRC Press|location=Boca Raton, Florida|isbn=0849326737|page=619}} 7. ^{{cite web|title=Baeuerlen, William (1840 - 1917)|url=http://www.anbg.gov.au/biography/baeuerlen-william.html|publisher=Australian National Botanic Garden|accessdate=22 December 2016}} External links
