It has fibrous bark and pink to purple flowers in spikes, mostly on the side branches. DescriptionMelaleuca subfalcata is a shrub which grows to a height of {{convert|3-4|m|ft|sigfig=2|abbr=on}} and has rough, fibrous bark. Its leaves are arranged alternately and are {{convert|8-23|mm|in|sigfig=1|abbr=on}} long, {{convert|0.9-2|mm|in|sigfig=1|abbr=on}} wide, linear to narrow elliptic in shape and curved, so that they are almost sickle-shaped.[1]The flowers are a shade of pink to purple, arranged in a spike on the sides of the branches and sometimes on the ends of branches that continue to grow after flowering. The spikes are up to {{convert|27|mm|in|sigfig=1|abbr=on}} in diameter and contain 5 to 30 individual flowers. The petals are {{convert|2.5-4.5|mm|in|sigfig=1|abbr=on}} long and fall off as the flowers mature. The stamens are arranged in five bundles around the flower, each bundle with 11 to 22 stamens. Flowers appear from November to March and the fruit which follow are woody capsules, {{convert|2.5-3.5|mm|in|sigfig=1|abbr=on}} long, sometimes arranged in clusters.[1][2] Taxonomy and namingMelaleuca subfalcata was first formally described in 1847 by Nikolai Turczaninow in "Bulletin de la classe physico-mathematique de l'Academie Imperiale des sciences de Saint-Petersburg".[3][4] The specific epithet (subfalcata) is from the Latin word falcatus meaning "curved" or "sickle-shaped"[5]{{rp|237}} and the prefix -sub meaning “under”[5]{{rp|826}} in reference to the leaves being curved, almost like a sickle.[1]Distribution and habitatThis melaleuca occurs in and between the Ongerup, Lake King and Israelite Bay districts[1] in the Esperance Plains, Jarrah Forest and Mallee biogeographic regions.[6] It grows in sand or clay over laterite on undulating plains and rocky hillsides.[7] ConservationMelaleuca subfalcata is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[6]References1. ^1 2 3 {{cite book|last1=Brophy|first1=Joseph J.|last2=Craven|first2=Lyndley A.|last3=Doran|first3=John C.|title=Melaleucas : their botany, essential oils and uses|date=2013|publisher=Australian Centre for International Agricultural Research|location=Canberra|isbn=9781922137517|page=349}} {{Taxonbar|from=Q15371665}}2. ^{{cite book|last1=Holliday|first1=Ivan|title=Melaleucas : a field and garden guide|date=2004|publisher=Reed New Holland Publishers|location=Frenchs Forest, N.S.W.|isbn=1876334983|pages=278–279|edition=2nd}} 3. ^1 {{cite web|title=Melaleuca subfalcata|url= https://biodiversity.org.au/boa/instance/apni/544518|publisher=APNI|accessdate=25 April 2015}} 4. ^{{cite book|last1=Turczaninow|first1=Nikolai|title=Bulletin de la classe physico-mathematique de l'Academie Imperiale des sciences de Saint-Petersburg, Volumes 10-11|date=1852|location=St. Petersburg|page=342|url=https://books.google.com.au/books?id=qSAYAAAAYAAJ&pg=PA191&dq=melaleuca+laxiflora&hl=en&sa=X&ei=UjsFVeraNoeZ8QX1u4KoAg&ved=0CCUQ6AEwAg#v=onepage&q=melaleuca%20rigidifolia&f=false|accessdate=25 April 2015}} 5. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 6. ^1 {{FloraBase|name=Melaleuca subfalcata|id = 5974}} 7. ^{{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=398}} 5 : Melaleuca|Myrtales of Australia|Flora of Western Australia|Plants described in 1847|Endemic flora of Western Australia |
