It has wavy, stem-clasping, blue-green leaves and spikes of pink flowers in spring. DescriptionMelaleuca spicigera is a shrub with dark, fibrous bark growing to a height of {{convert|2-3|m|ft|sigfig=1|abbr=on}} and with branchlets that are covered with soft hairs. Its leaves are arranged alternately, {{convert|5-15|mm|in|sigfig=1|abbr=on}} long and {{convert|2-6|mm|in|sigfig=1|abbr=on}} wide, heart-shaped to oblong and tapering to a blunt point. The leaves are of a blue-green colour, lack a stalk and are wavy or dished, only rarely flat.[1]The flowers are a shade of pink to purple and are arranged in short spikes on the sides of the branches. Each spike contains 3 to 29 individual flowers and is up to {{convert|20|mm|in|sigfig=2|abbr=on}} in diameter. The petals are {{convert|2.4-3.1|mm|in|sigfig=1|abbr=on}} long and fall off as the flowers mature. The stamens are arranged in five bundles around the flowers and there are 9 to 16 stamens per bundle. The flowering period is in September or October and is followed by fruit which are woody capsules {{convert|5-6|mm|in|sigfig=1|abbr=on}} long with teeth around the edges and in clusters along the branches.[1][2][3] Taxonomy and namingMelaleuca spicigera was first formally described in 1902 by Spencer Le Marchant Moore in Journal of Botany[4] from a specimen collected by James Drummond in 1843. The specific epithet (spicigera) is from a Latin word spīca meaning “ear of grain”[5] in reference to the flowers being arranged in a spike.[1]Distribution and habitatThis melaleuca occurs in and between the Ongerup, Dowerin and Salmon Gums districts[1][2] in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee biogeographic regions.[6] It grows in sandy, clayey or gravelly soils on undulating plains.[7] ConservationMelaleuca spicigera is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[6]Use in horticultureThis species is ornamental and hardy in cultivation in temperate regions, growing in well-drained soils in full sun or semi-shade. It is frost tolerant.[2] 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=334}} {{Taxonbar|from=Q15371886}}2. ^1 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=178–179|edition=2nd}} 3. ^{{cite journal|last1=Moore|first1=Spencer le Marchant|title=Melaleuca spicigera|journal=Journal of Botany, British and Foreign|date=1902|volume=40|page=25}} 4. ^1 {{cite web|title=Melaleuca spicigera|url= https://biodiversity.org.au/boa/instance/apni/543963|publisher=APNI|accessdate=24 April 2015}} 5. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=735}} 6. ^1 {{FloraBase|name=Melaleuca spicigera|id = 5969}} 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=397}} 5 : Melaleuca|Myrtales of Australia|Flora of Western Australia|Plants described in 1902|Endemic flora of Western Australia |
