(In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca arcuata.)[1] It is a similar shrub to Calothamnus formosus but has larger flowers and fruit. DescriptionCalothamnus cupularis is a shrub growing to a height of about {{convert|1.2|m|ft|sigfig=1}} with stems that are hairy at first but become glabrous over time. Its leaves are needle-like, mostly {{convert|40-100|mm|in|sigfig=1}} long and {{convert|1.0-1.3|mm|in|sigfig=1}} wide, circular in cross section and tapering at the end to a sharp point.[2]The flowers are bright red and have 5 petals and 5 claw-like bundles of stamens, each about {{convert|35-38|mm|in|sigfig=2}} long. The sepals have a thickened rib in their centre and wide papery margins. The petals are {{convert|7-8|mm|in|sigfig=2}} long. Flowering occurs in September or October and is followed by fruits which are woody, smooth, cylindrical capsules, {{convert|12-14|mm|in|sigfig=2}} long.[2] Taxonomy and namingCalothamnus cupularis was first formally described in 2010 by Alex George from a specimen found in the Kalbarri National Park.[2][3] The specific epithet (cupularis) is from the Latin word cupula meaning "a small tub" or "a cask"[4] referring to the shape of the fruits of this species.[2]Distribution and habitatCalothamnus cupularis occurs in a small area in the Kalbarri National Park,[2] in the Geraldton Sandplains biogeographic region[5] where it grows in sand in kwongan.[2]ConservationCalothamnus cupularis is classified as "priority 2" by the Western Australian government Department of Parks and Wildlife[5] meaning that is poorly known and from one or a few locations.[6]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=30 June 2014|volume=63|issue=3|pages=663–670|doi=10.12705/633.38|url=http://www.ingentaconnect.com/content/iapt/tax/2014/00000063/00000003/art00017|accessdate=23 July 2015}} {{Taxonbar|from=Q17590506}}2. ^1 2 3 4 5 {{cite journal|last1=George|first1=Alex S.|title=Calothamnus (Myrtaceae): precursor paper to Flora of Australia|journal=Nuytsia|date=2010|volume=20|pages=188–189|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/588.pdf|accessdate=26 July 2015}} 3. ^{{cite web|title=Calothamnus cupularis|url=https://biodiversity.org.au/boa/instance/apni/662772|publisher=APNI|accessdate=26 July 2015}} 4. ^{{cite web|title=cupula|url=https://en.wiktionary.org/wiki/cupula|accessdate=26 July 2015}} 5. ^1 {{cite web|title=Calothamnus cupularis|url=https://florabase.dpaw.wa.gov.au/browse/profile/35697|publisher=FloraBase|accessdate=26 July 2015}} 6. ^{{cite web|title=Conservation codes for Western Australian Flora and Fauna|url=http://www.dpaw.wa.gov.au/images/documents/plants-animals/threatened-species/Listings/conservation_code_definitions.pdf|publisher=Government of Western Australia Department of Parks and Wildlife|accessdate=25 July 2015}} 5 : Calothamnus|Myrtales of Australia|Flora of Western Australia|Plants described in 2010|Endemic flora of Western Australia |
