It is an erect shrub with bright red flowers in spring and large, almost spherical fruit. It has a limited distribution near Hopetoun. (In 2014 Craven, Edwards and Cowley proposed that the species be renamed Melaleuca macrocarpa.)[1] DescriptionCalothamnus macrocarpus is an erect shrub with many branches growing to a height of about {{convert|2-3|m|ft|sigfig=1}}. Its leaves are crowded, {{convert|20-30|mm|in|sigfig=1}} long, {{convert|1-2|mm|in|sigfig=1}} in diameter, cylindrical in shape and taper to a non-prickly point. There are prominent oil glands on the leaves.[2][3]The flowers are deep red usually in small clusters between the leaves. The petals are {{convert|6-8|mm|in|sigfig=1}} long, thin, papery and pink to brown. The stamens are arranged in 5 claw-like bundles usually with 26 to 28 stamens per bundle. Flowering occurs from August to December and is followed by fruits which are woody, almost spherical capsules, {{convert|13-18|mm|in|sigfig=1}} in diameter, which are often hidden in the foliage.[2] Taxonomy and namingCalothamnus macrocarpus was first formally described in 1984 by Trevor Hawkeswood in the botanical journal Nuytsia.[2][4] The specific epithet (macrocarpus) is from the Ancient Greek words μακρός (makrós) meaning "long"[5] and Καρπός (Karpós) meaning "fruit"[6] referring to the unusually large fruit of this species.[2]Distribution and habitatCalothamnus macrocarpus occurs near the summit of East Mount Barren near Hopetoun in the Esperance Plains biogeographic region[2][3] where it grows in sand and soils derived from quartzite.[7]ConservationCalothamnus macrocarpus is classified as "Priority Two" by the Western Australian government department of parks and wildlife,[3] meaning that it is poorly known and from only one or a few locations, mostly in reserves or national parks.[8]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|page=666|doi=10.12705/633.38|url=http://www.ingentaconnect.com/content/iapt/tax/2014/00000063/00000003/art00017|accessdate=23 July 2015}} {{Taxonbar|from=Q15396995}}2. ^1 2 3 4 {{cite journal|last1=Hawkeswood|first1=Trevor J.|title=Nine new species of Calothamnus Labill.
