A small shrub producing a profusion of strongly scented pink to red flowers in dense clusters from July to September. DescriptionHakea circumulata is a non lignotuberous compact or low open shrub typically growing to a height of {{convert|0.6|to|1.5|m|ft|1}}. Smaller branches are densely covered with short, soft, flattened rusty coloured hairs. The rigid needle-shaped leaves are {{convert|1-5|cm|in|sigfig=2|abbr=on}} long and {{convert|0.9-1.7|mm|in|sigfig=2|abbr=on}} wide. The leaves grow upright, slightly tapering with a very sharp point at the apex. The inflorescence consists of 6-12 strongly scented white, pink or reddish brown clusters of flowers. Inflorescence are supported on a stem {{convert|1.5-2|mm|in|sigfig=2|abbr=on}} long covered in long soft hairs. The bracts surrounding the flowers are {{convert|3-5|mm|in|sigfig=2|abbr=on}} long. The pedicels are {{convert|2.5-7|mm|in|sigfig=2|abbr=on}} long with white hairs, occasionally with glands on the tips. The white and pink perianth are smooth or having coarse longish hairs. The style is {{convert|8-11.5|mm|in|sigfig=2|abbr=on}} long. Flowers appear in leaf axils on the smaller branches from July to September. Fruit are erect on the stem, egg-shaped and often solitary ending in two prominent horns. The surface is smooth in between the many small rounded protuberances. The fruit have two winged, silky, dark brown seeds and are retained on the shrub.[2][3][4][5]Taxonomy and namingHakea circumalata was first formally described by botanist Carl Meisner in 1855 and the description was published in Hooker's Journal of Botany and Kew Garden Miscellany.[1][5] The specific epithet (circumalata) is derived from the Latin word circus meaning "around"[6]{{rp|346}} and alatus meaning "winged"[6]{{rp|77}} referring to the seed which is surrounded by a wing.[7]Distribution and habitatHakea circumalata grows from Shark Bay ranging south through to Wongan Hills and Corrigin. It grows on clay, deep sand and sand with lateritic gravel in heath and low woodland. Requires full sun and a well drained site. An ornamental species that tolerates moderate frosts. A good wildlife habitat due to its prickly dense growth habit.[2][3]Conservation statusHakea circumalata is classified as "not threatened" by the Western Australian government Department of Parks and Wildlife.[8]References1. ^1 {{cite web |title=Hakea circumalata |url=https://biodiversity.org.au/nsl/services/search?product=APNI&tree.id=&name=Hakea+circumalata&inc._scientific=&inc.scientific=on&inc._cultivar=&inc._other=&max=100&display=apni&search=true |publisher=APNI |accessdate=22 January 2019}} {{Taxonbar|from=Q18082847}}2. ^1 {{cite book |last1=Young |first1=J A |title=Hakeas" of Western Australia: A Field and Identification Guide |date=2006 |publisher=J A Young |isbn=0-9585778-2-X}} 3. ^1 {{cite book |last1=Holliday |first1=Ivan |title=Hakeas:A Field and Garden Guide |date=2005 |publisher=Reed New Holland |isbn=1-877069-14-0}} 4. ^{{cite book |last1=Wilson (ed) |first1=Annette |last2=Barker |first2=Robyn M. |last3=Haegi |first3=Laurence A. |last4=Barker |first4=William R. |title="Flora of Australia" |date=1999 |publisher=Department of Environment & Heritage |location=Canberra/Melbourne |isbn=0-643-06454-0}} 5. ^{{cite book |last1=Meisner |first1=Carl |last2=Hooker |first2=William Jackson (ed.) |title=Journal of Botany and Kew Garden Miscellany (Volume 7) |date=1855 |publisher=Lovell Reeve |location=London |page=114 |url=https://www.biodiversitylibrary.org/item/6325#page/116/mode/1up |accessdate=28 January 2019}} 6. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 7. ^1 {{cite web |title=Hakea circumalata |url=http://www.flora.sa.gov.au/efsa/lucid/Hakea/key/Australian%20Hakea%20species/Media/Html/Hakea_circumalata.htm |website=Flora of South Australia:Online |publisher=South Australian Government |accessdate=22 January 2019}} 8. ^{{cite web |title=Hakea circumalata |url=https://florabase.dpaw.wa.gov.au/browse/profile/2140 |website=FloraBase |publisher=Western Australian Government |accessdate=22 January 2019}} 4 : Hakea|Eudicots of Western Australia|Plants described in 1855|Taxa named by Carl Meissner |
