It is a densely-branched, densely-foliaged large shrub or tree with sprays of large white flowers with a red centre. DescriptionKunzea amathicola is a densely-branched large shrub or tree which grows to a height of up to {{convert|15|m|ft|sigfig=1|abbr=on}} but is commonly a dense, rounded shrub {{convert|2|m|ft|sigfig=1|abbr=on}} high and {{convert|3|m|ft|sigfig=1|abbr=on}} wide with interwoven branches. The branches are densely covered with silky hairs and the leaves are of two forms, juvenile and mature. Adult leaves are oblong, lance-shaped to egg-shaped, {{convert|6-12|mm|in|sigfig=1|abbr=on}} long and {{convert|2-4|mm|in|sigfig=1|abbr=on}} wide while the juvenile leaves are egg-shaped, {{convert|2.5-5|mm|in|sigfig=1|abbr=on}} long and {{convert|1-2.5|mm|in|sigfig=1|abbr=on}} wide. The flowers are arranged in groups of between five and twenty flowers and the individual flowers are {{convert|7-12.5|mm|in|sigfig=1|abbr=on}} in diameter. The floral cup is {{convert|2-4|mm|in|sigfig=1|abbr=on}} long and {{convert|3-6|mm|in|sigfig=1|abbr=on}} in diameter. The sepal lobes are {{convert|0.5-1.5|mm|in|sigfig=1|abbr=on}} long and {{convert|0.5-2|mm|in|sigfig=1|abbr=on}} wide. The petals are white, more or less round to egg-shaped, about {{convert|2-4|mm|in|sigfig=1|abbr=on}} long and wide and there are between 38 and 90 white stamens. Flowers are present in most months and the fruit are hemispherical capsules which are {{convert|2-5|mm|in|sigfig=1|abbr=on}} long and {{convert|3.5-6|mm|in|sigfig=1|abbr=on}} wide.[2][3]Taxonomy and namingKunzea amathicola was first formally described in 2014 by Peter James de Lange and Hellmut Toelken and the description was published in PhytoKeys.[1][3] The specific epithet (amathicola) is derived from the Ancient Greek words amathos meaning "sand"[4]{{rp|678}} and -cola meaning "dweller"[4]{{rp|217}} referring to the usual habitat of this species.[3]Distribution and habitatThis kunzea usually grows on sand dunes or in sandy soils in coastal and near-coastal areas on both the North and South Islands as well as the Little Barrier Island. In the North Island it is most common on the west coast between Wellington and Te Paki and in the South Island from Farewell Spit to West Whanganui Inlet.[3] Use in horticultureRawiritoa is most easily propagated from fresh seed and is fast-growing is a sunny position in well-drained soil.[3] References1. ^1 {{WCSP | 491043 | Kunzea amathicola }} {{Taxonbar|from=Q21274379}}2. ^{{cite web|last1=de Lange|first1=Peter J.|title=Kunzea amathicola|url=http://nzpcn.org.nz/flora_details.aspx?ID=7639|publisher=New Zealand Plant Conservation Network|accessdate=31 August 2017}} 3. ^1 2 3 4 {{cite journal|last1=de Lange|first1=Peter|title=A revision of the New Zealand Kunzea ericoides (Myrtaceae) complex|journal=PhytoKeys|date=26 August 2014|volume=40|pages=112–127|doi=10.3897/phytokeys.40.7973}} 4. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 3 : Kunzea|Endemic flora of New Zealand|Plants described in 2014 |
