It is a small, spreading shrub with needle-shaped leaves and clusters of red flowers with 5 petals and 5 stamen bundles. (In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca augusti-oldfieldii.)[1] DescriptionCalothamnus oldfieldii is a small shrub growing to a height of about {{convert|1.5|m|ft|sigfig=1}}. Its leaves are {{convert|25-50|mm|in|sigfig=1}} long and nearly circular in cross section and taper to a pointed end.[2][3]The flowers are bright red and arranged in small groups and the stamens are arranged in 5 claw-like bundles. Flowering occurs from July to November and is followed by fruits which are woody capsules about {{convert|5|mm|in|sigfig=1}} long.[2][3] Taxonomy and namingCalothamnus oldfieldii was first formally described by Victorian Government Botanist Ferdinand von Mueller in 1862 in Volume 3, Part 21 of Fragmenta Phytographiae Australiae.[4][5] The specific epithet (oldfieldii) honours Augustus Frederick Oldfield, an English botanist and plant collector. Distribution and habitatCalothamnus oldfieldii occurs in the Carnarvon, Geraldton Sandplains and Yalgoo biogeographic regions[3] where it grows in sandy kwongan.[2][6]ConservationCalothamnus oldfieldii is classified as "not threatened" by the Western Australian government department of parks and wildlife.[3]References1. ^{{cite journal|last1=Craven|first1=Lyn A.|last2=Edwards|first2=Robert D.|last3=Cowley|first3=Kirsten J.|title=New combinations and names in Melaleuca (Myrtaceae)|journal=Taxon|date=31 July 2014|volume=63|issue=3|page=665|doi=10.12705/633.38|url=http://www.ingentaconnect.com/content/iapt/tax/2014/00000063/00000003/art00017|accessdate=31 July 2015}} {{Taxonbar|from=Q15397365}}2. ^1 2 {{cite book|last1=Corrick|first1=Margaret G.|last2=Fuhrer|first2=Bruce A.|title=Wildflowers of southern Western Australia|date=2009|publisher=Rosenberg Publishing P/L|location=Kenthurst, N.S.W.|isbn=9781877058844|page=115|edition=3rd|url=https://books.google.com.au/books?id=gzgsXMXxAd0C&pg=PA115&lpg=PA115&dq=Calothamnus+oldfieldii&source=bl&ots=408x__wN53&sig=2JQ1wziMrNB9pi1TE0nFNG2rECM&hl=en&sa=X&ved=0CEgQ6AEwCmoVChMIlK2BvuOExwIVhRWmCh043wbY#v=onepage&q=Calothamnus%20oldfieldii&f=false|accessdate=31 July 2015}} 3. ^1 2 3 {{cite web|title=Calothamnus oldfieldii|url=https://florabase.dpaw.wa.gov.au/browse/profile/5420|publisher=FloraBase|accessdate=31 July 2015}} 4. ^1 {{cite web|title=Calothamnus oldfieldii|url=https://biodiversity.org.au/boa/instance/apni/527459|publisher=APNI|accessdate=31 July 2015}} 5. ^{{cite book|last1=von Mueller|first1=Ferdinand|title=Fragmenta Phytographiae Australiae (Volume 3)|date=1862|location=Melbourne|page=31|url=https://www.biodiversitylibrary.org/item/7220#page/120/mode/1up|accessdate=31 July 2015}} 6. ^{{cite book|last1=Paczkowska|first1=Grazyna|last2=Chapman|first2=Alex R.|title=The Western Australian flora : a descriptive catalogue|date=2000|publisher=Wildflower Society of Western Australia|location=Perth|isbn=0646402439|page=351}} 5 : Calothamnus|Myrtales of Australia|Flora of Western Australia|Plants described in 1862|Endemic flora of Western Australia |
