It is distinguished by its small, decussate leaves and small flower heads which rarely have more than one flower in each inflorescence. DescriptionMelaleuca subalaris is a shrub or sometimes a small tree growing to about {{convert|5|m|ft|sigfig=1|abbr=on}} tall with branches and leaves that are glabrous when mature. Its leaves are arranged in alternating pairs, each pair at right angles to the ones above and below (decussate) so that the leaves form four rows along the stems. Each leaf is {{convert|1.8-3.7|mm|in|sigfig=1|abbr=on}} long and {{convert|0.9-1.5|mm|in|sigfig=1|abbr=on}} wide, narrow oval to egg-shaped, oval in cross-section and with a blunt end.[1]The flowers are white to pale yellow and arranged on the side branches. Sometimes there are up to 4 single flowers in a head up to {{convert|12|mm|in|sigfig=1|abbr=on}} in diameter. The stamens are arranged in five bundles around the flowers and there are 8 to 18 stamens per bundle. The main flowering period is in September and October and is followed by fruit which are woody capsules {{convert|3–4|mm|in|sigfig=1|abbr=on}} long forming loose clusters on the old wood.[1][2] Taxonomy and namingMelaleuca subalaris was first formally described in 1988 by Bryan Barlow in Australian Systematic Botany.[3][4] The specific epithet (subalaris) is from the Latin word alaris meaning "of the wing"[5]{{rp|77}} and the prefix -sub meaning “under”[5]{{rp|826}} referring to the flowers being in a spike rather than axillary.[1]Distribution and habitatThis melaleuca occurs in and between the Peak Charles, Zanthus and Esperance districts[2] in the Coolgardie, Esperance Plains, Mallee biogeographic regions.[6] It grows in clay or sandy soils on the edges of salt pans.[7] ConservationMelaleuca subalaris is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[6]References1. ^1 2 {{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=347}} {{Taxonbar|from=Q15371524}}2. ^1 {{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|page=132|edition=2nd}} 3. ^{{cite journal|last1=Barlow|first1=BA|last2=Cowley|first2=KJ|title=Contributions to a revision of (Myrtaceae): 4–6|journal=Australian Systematic Botany|date=1988|volume=1|issue=2|page=102|doi=10.1071/SB9880095}} 4. ^1 {{cite web|title=Melaleuca subalaris|url= https://biodiversity.org.au/boa/instance/apni/544467|publisher=APNI|accessdate=24 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 subalaris|id = 18526}} 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 1988|Endemic flora of Western Australia |
