It is a many-branched shrub with the leaves arranged in a way that gives the plant the appearance of a conifer. DescriptionMelaleuca araucarioides is a small to medium tree, about {{convert|0.5-1.5|m|ft|sigfig=1|abbr=on}} high and wide with rough bark. Its leaves are fleshy and glabrous, about {{convert|2-6|mm|in|sigfig=1|abbr=on}} long and {{convert|1-2|mm|in|sigfig=1|abbr=on}} wide. They are crowded and arranged in groups of three forming six rows of leaves along the branches.[1][2][3]The flowers are pale cream-coloured in one or two heads on the ends of the younger branches or often on older wood. The heads of flowers are about {{convert|14-16|mm|in|sigfig=2|abbr=on}} in diameter. As with other melaleucas, the stamens are joined in bundles and in this species there are usually only 3 stamens per bundle. Flowers appear in spring and are followed by fruit which are woody capsules {{convert|2.5-3.5|mm|in|sigfig=2|abbr=on}} long, {{convert|2-4.3|mm|in|sigfig=1|abbr=on}} in diameter forming small, tight clusters with the thickened sepals remaining as teeth.[1][2][3] Taxonomy and namingMelaleuca araucarioides was first formally described in 1988 by Bryan Barlow in Nuytsia (journal) as a new species. It had formerly been included in Melaleuca blaeriifolia Turcz. to which it is closely related.[4] The specific epithet (araucarioides) "alludes to the superficial resemblance of the leafy shoots to those of the gymnosperm genus Araucaria Juss.". It is distuished from M. blaeriifolia mainly on the basis of the distinctive, regular leaf arrangement and the smaller size of the fruits.[2]Distribution and habitatThis melaleuca is confined to the Ongerup-Cape Riche area in the Esperance plains and Mallee biogeographic regions of Western Australia.[5] It grows in well-drained sandy or loamy soils in heaths or open woodlands.[2] ConservationMelaleuca araucarioides is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[5]References1. ^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|pages=20–21|edition=2nd}} {{Taxonbar|from=Q15369836}}2. ^1 2 3 {{cite journal|last1=Quinn|first1=F.C.|last2=Cowley|first2=K.J.|last3=Barlow|first3=Bryan A.|last4=Thiele|first4=K.R.|title=New names and combinations for some Melaleuca (Myrtaceae) species and subspecies from the south-west of Western Australia considered rare or threatened|journal=Nuytsia|date=1998|volume=8|issue=3|pages=334–350|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/184.pdf|accessdate=5 March 2015}} 3. ^1 {{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=77|url=http://aciar.gov.au/files/mn156-species-a-c_1.pdf|accessdate=16 March 2015}} 4. ^{{cite web|title=Melaleuca araucarioides|url=https://biodiversity.org.au/boa/instance/apni/552672|publisher=APNI|accessdate=16 March 2015}} 5. ^1 {{FloraBase|name=Melaleuca araucarioides|id = 13268}} 5 : Melaleuca|Myrtales of Australia|Flora of Western Australia|Plants described in 1998|Endemic flora of Western Australia |
