It is a sprawling shrub with thin stems, hairy young shoots, pinnate leaves and pink, four-petalled flowers over a long period. DescriptionBoronia keysii is an open, thin-stemmed, sprawling shrub that typically grows to a height and width of about {{convert|2|m|ft|sigfig=1|abbr=on}}. The young stems are covered with brownish, star-shaped hairs. It has pinnate leaves with a single, or three, five or seven leaflets {{convert|8-75|mm|in|sigfig=1|abbr=on}} long, {{convert|4-40|mm|in|sigfig=1|abbr=on}} wide in outline. The leaves are arranged in opposite pairs and lack a petiole. The leaflets are elliptic to lance-shaped, the end leaflet {{convert|15-51|mm|in|sigfig=1|abbr=on}} long and {{convert|3-12|mm|in|sigfig=1|abbr=on}} wide and longer than the side leaflets. The flowers are arranged arranged in groups of between three and six on a peduncle {{convert|3-5|mm|in|sigfig=1|abbr=on}} long, the individual flowers on a pedicel {{convert|5-15|mm|in|sigfig=1|abbr=on}} long. The four sepals are egg-shaped to triangular, {{convert|2.5-3.5|mm|in|sigfig=1|abbr=on}} long with a hairy back. The four petals are deep rose pink to white, {{convert|5.5-8|mm|in|sigfig=1|abbr=on}} long and {{convert|3-4.5|mm|in|sigfig=1|abbr=on}} and hairy on the back. There are eight stamens with the four nearest the sepals slightly long than the four near the petals. Flowering occurs throughout the year but mostly from May to November. The fruit is a capsule {{convert|4.5-5|mm|in|sigfig=2|abbr=on}} long and {{convert|1.5-2|mm|in|sigfig=2|abbr=on}} wide containing four black seeds.[2][3][4]Taxonomy and namingBoronia keysii was first formally described in 1926 by Karel Domin from specimens collected by James Keys at Lake Cootharaba in 1909. The description was published in the journal Bibliotheca Botanica published in Stuttgart under the heading Beitrage zur Flora und Pflanzengeographie Australiens (Contributions to the Flora and Plant Geography of Australia).[5][6][7] The specific epithet (keysii) honours the collector of the type specimen. Distribution and habitatKey's boronia is usually found in the ecotone between forest and heath and commonly as a uderstorey species in open forest. It is only known from the Cooloola region near Lake Cootharaba.[8] ConservationBoronia keysii is listed as "vulnerable" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 and the Queensland Government Nature Conservation Act 1992. The main threats to the species include changes to the water table, inappropriate fire regimes and invasion by exotic pines from nearby plantations.[8][9]References1. ^{{cite web|title=Boronia keysii|url= https://biodiversity.org.au/nsl/services/apc-format/display/60240|publisher=APC|accessdate=27 March 2019}} 2. ^1 {{cite web |title=Key's boronia - Boronia keysii |url=https://wetlandinfo.des.qld.gov.au/wetlands/ecology/components/species/?boronia-keysii |publisher=Queensland Government Department of Environment and Science |accessdate=27 March 2019}} 3. ^{{cite journal |last1=Duretto |first1=Marco F. |title=Systematics of Boronia section Valvatae sensu lato (Rutaceae) |journal=Muelleria |date=1999 |volume=12 |issue=1 |pages=52–54 |url=https://www.rbg.vic.gov.au/documents/Pages_from_Muelleria_12(1),_p47-86,_Duretto,_Sytematics_Boronia-2.pdf |accessdate=27 March 2019}} 4. ^{{cite web |last1=Duretto |first1=Marco F. |last2=Wilson |first2=Paul G. |last3=Ladiges |first3=Pauline Y. |title=Boronia keysii |url=https://profiles.ala.org.au/opus/foa/profile/Boronia%20keysii |publisher=Australian Biological Resources Study, Department of the Environment and Energy, Canberra |accessdate=27 March 2019}} 5. ^{{cite web|title=Boronia keysii|url= https://id.biodiversity.org.au/instance/apni/465178|publisher=APNI|accessdate=27 March 2019}} 6. ^{{cite web|title=Keys, James (1841-1916) F.L.S.|work=Collectors & Illustrators| publisher=Australian National Herbarium|url=http://www.cpbr.gov.au/biography/keys-james.html|accessdate=14 April 2014}} 7. ^{{cite journal |last1=Henderson |first1=Rodney John Francis |title=Bibliography of Karel Domin's Beiträge on Australian Plants |journal=Taxon |date=1984 |volume=33 |issue=4 |pages=673–679 |doi=10.2307/1220784}} 8. ^1 {{cite web |title=Approved Conservation Advice for Boronia keysii (Key’s Boronia) |url=http://www.environment.gov.au/biodiversity/threatened/species/pubs/21632-conservation-advice.pdf |publisher=Australian Government Department of the Environment |accessdate=27 March 2019}} 9. ^{{cite web|work=SPRAT Profile|title=Boronia keysii — Key's Boronia |publisher=Department of the Environment | accessdate=14 April 2014|url=http://www.environment.gov.au/cgi-bin/sprat/public/publicspecies.pl?taxon_id=21632}} External links
