This plant was previously classified as Agonis juniperina but is now part of the Taxandria genus. The Noongar peoples know the tree as watti.[1] DescriptionTaxandria juniperina occurs mostly as an erect tree or shrub that usually grows to less than {{convert|10|m|ft|0}} as a dense shrub but can grow up to {{convert|27|m|ft|0}} in its native environment. It has fibrous brown bark that is a light red colour on the underside. It grows as a dense shrub in space or as a tall erect tree when part of a thicket. When the leaves and young stems are bruised they release a spicy perfume from which the plant is recognised to be a member of the family Myrtaceae. It is closely related to Leptospermum (Tea Tree).[2]The tree has evergreen foliage with very narrow leaves, usually 7–13mm long and 0.3–1.5 mm wide. The flowers produced by T. juniperina occur between February to November and are described as upright whitish spikes. Each flower is white with some pink, 5 mm in diameter.[3] The species is distinguished from other members of the genera by its tree habit and the leaves which are typically {{convert|7|to|13|mm|in|2}} length and usually flat to very slightly concave above and convex below. It also has glabrous sepals.[4] Distribution and habitatTaxandria juniperina occurs in a coastal strip in the south west corner of western Australia from Busselton south to Augusta to Waychinicup just east of Albany.[4] The tree prefers margins of winter-wet or permanent swamps or watercourses, but grows in a range of soil types from loam and peat to sand and gravel.[5]ClassificationFirst formally described by the botanist Johannes Conrad Schauer in 1844 as part of Johann Georg Christian Lehmann's work Plantae Preissianae. The plant was subsequently reclassified to Taxandria juniperina in a 2007 revision by Wheeler and Marchant into the new genus Taxandria.[6] References1. ^{{cite web|url=http://www.kippleonline.net/bobhoward/plantsframe.html|title=Noongar names for plants|accessdate=24 November 2016|publisher=kippleonline.net|deadurl=yes|archiveurl=https://web.archive.org/web/20161120071826/http://www.kippleonline.net/bobhoward/plantsframe.html|archivedate=20 November 2016|df=}} {{Taxonbar|from=Q7689503}}2. ^{{cite web|url=http://www.anbg.gov.au/gnp/gnp3/agonis-juniperina.html|title=Australian National Botanic Gardens - Agonis Juniperina|year=2007|accessdate=2007-06-05}} 3. ^{{cite web|url=http://www.desert-tropicals.com/Plants/Myrtaceae/Agonis_juniperina.html|title=Desert Tropicals - Juniper Myrtle|year=2007|accessdate=2007-06-05}} 4. ^1 {{cite web|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/414.pdf|title=A revision of the Western Australian genus Agonis (Myrtaceae) and two new segregate genera Taxandria and Paragonis|work=Nuytsia|year=2007|accessdate=29 December 2016|publisher=Western Australian Herbarium}} 5. ^{{cite web|url=http://florabase.calm.wa.gov.au/browse/flora?f=273&level=s&id=20115|title=Taxandria Juniperina - FloraBase - The West Australian Flora|year=2007|accessdate=2007-06-05}} 6. ^{{cite web|url=http://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2888846#names|title=Taxandria juniperina (Schauer) J.R.Wheeler & N.G.Marchant|accessdate=15 December 2016|work=Atlas of Living Australia|publisher=Global Biodiversity Information Facility}} 6 : Taxandria (plant)|Myrtales of Australia|Rosids of Western Australia|Trees of Australia|Trees of Mediterranean climate|Plants described in 1844 |
