It is similar to Melaleuca ciliosa with its hairy young leaves and heads of yellow flowers ageing to red but there are fewer flowers in each head and the leaves are generally smaller. DescriptionMelaleuca lara is a shrub sometimes growing to {{convert|1.5|m|ft|sigfig=1|abbr=on}} tall and wide with branchlets that have soft hairs at first but become glabrous with age. Its leaves are arranged alternately and are {{convert|4.5-8.5|mm|in|sigfig=1|abbr=on}} long, {{convert|2.8-3.8|mm|in|sigfig=2|abbr=on}} wide, flat, elliptical or egg-shaped and covered with short, soft hairs, especially when young. The oil glands are distinct.[1][2]The flowers are bright yellow fading to red, arranged in heads on the ends of branches which continue to grow after flowering and sometimes also in the upper leaf axils. The heads are up to {{convert|25|mm|in|sigfig=1|abbr=on}} in diameter with 2 to 5 groups of flowers in threes. The petals are {{convert|1.9-3|mm|in|sigfig=1|abbr=on}} long and fall off as the flower ages. There are five bundles of stamens around the flower, each with 9 to 13 stamens. Flowering occurs in early spring and is followed by fruit which are woody capsules, {{convert|4-5.5|mm|in|sigfig=1|abbr=on}} long in loose clusters along the stem.[1][2] Taxonomy and namingMelaleuca lara was first formally described in 1999 by Lyndley Craven in Australian Systematic Botany from a specimen near the Z Bend lookout on the Murchison River in the Kalbarri National Park.[3][4] The specific epithet (lara) is derived from the Ancient Greek word laros meaning "agreeable", "pleasant" or "lovely"[5] referring to the flowers of this plant species.[1]Distribution and habitatMelaleuca lara occurs in the Kalbarri district[1] in the Geraldton Sandplains biogeographic region.[6] It grows in sand in heath on sandplains near river gorges.[1]ConservationMelaleuca lara is listed as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.[6]References1. ^1 2 3 4 {{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=213}} {{Taxonbar|from=Q6811052}}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=54|edition=2nd}} 3. ^{{cite web|title=Melaleuca lara|url= https://biodiversity.org.au/boa/instance/apni/561736|publisher=APNI|accessdate=13 May 2015}} 4. ^{{cite journal|last1=Craven|first1=L.
