The common name is the hard aspen. The habitat is dry rainforest, up to 700 metres above sea level. It grows from the upper Clarence River, New South Wales to Cape York Peninsula at the northernmost tip of Australia. It is also found on New Caledonia and Lord Howe Island.[1] The true aspens of the Northern Hemisphere belong to the genus Populus in the family Salicaceae.[2] TaxonomyAcronychia laevis was first described by German naturalists Johann Reinhold Forster and Georg Forster in 1775.[3] The specific epithet laevis is the Latin adjective "smooth", and refers to the new shoots and leaves.[4] It is a member of the Rutaceae family.[3]DescriptionIt grows as a bush or small tree up to 6 metres in height. It features attractive leaves, flowers, and pink fruit. The cylindrical trunk has fawn, fairly smooth bark. With some vertical lines and wrinkles. Small branches show leaf scars. Leaves are opposite on the stem, with only one leaflet. Leaf edges without serrations. Round, ovate, or obovate. Often blunt or rounded at the tip. 2.5 to 9.5 cm long, 1 to 5 cm wide.[4] Shiny on both sides. Oil dots may be seen under a lens with a bright light. The white or cream flowers appear on cymes from November to February. (Or as late as July). The fruit is a dark pink drupe, 6 to 8 mm wide.[5] Inside are reddish brown seeds, 4 mm long. Fruit matures from June to October. Germination is likely if the seeds are liberated from the pink fruit, then soaked. EcologyThe fruit is eaten by the green catbird.[5] CultivationAcronychia laevis can be grown in a sunny or part-shaded position in a garden. Its attractive fruit and flowers have horticultural appeal. It can be propagated from seed,[1] although cuttings may also be attempted. The fruit is edible to humans, although described as too pungent to be palatable,[6] and have even been likened to turpentine.[7]References{{Portal|Trees}}1. ^1 {{cite book | last1=Elliot | first1=Rodger W. | last2=Jones | first2=David L. | last3=Blake | first3=Trevor |title=Encyclopaedia of Australian Plants Suitable for Cultivation: Vol. 2|year=1985 |publisher=Lothian Press |location=Port Melbourne |isbn=0-85091-143-5|page=292}} {{Taxonbar|from=Q4676366}}{{DEFAULTSORT:Acronychia Laevis}}2. ^{{cite web|url=http://www.fpl.fs.fed.us/documnts/TechSheets/HardwoodNA/pdf_files/popaspeneng.pdf|title=technology transfer fact sheet: Populus spp.|work=Forest Products Laboratory: R&D USDA |publisher=United States Department of Agriculture Forest Service|location=Madison, Wisconsin|date=|accessdate=20 September 2010}} 3. ^1 {{APNI | name = Acronychia laevis J.R.Forst. & G.Forst. | id = 19566}} 4. ^{{cite web |title=Acronychia laevis|work=PlantNET - NSW Flora Online|url=http://plantnet.rbgsyd.nsw.gov.au/cgi-bin/NSWfl.pl?page=nswfl&lvl=sp&name=Acronychia~laevis|accessdate=2010-06-26}} 5. ^1 2 Floyd, A.G., Rainforest Trees of Mainland South-eastern Australia, Inkata Press 2008, {{ISBN|978-0-9589436-7-3}} page 345 6. ^{{cite web |url=http://www.brisrain.webcentral.com.au/01_cms/details_pop.asp?ID=14 |title=Acronychia laevis (RUTACEAE); Glossy acronychia, hard aspen |year=2007 |accessdate=27 June 2010 |work=Brisbane Rainforest Action & Information Network website |publisher=Brisbane Rainforest Action & Information Network |location=South Brisbane, Qld |deadurl=yes |archiveurl=https://web.archive.org/web/20110215231655/http://www.brisrain.webcentral.com.au/01_cms/details_pop.asp?ID=14 |archivedate=15 February 2011 |df=dmy }} 7. ^{{cite web|url=http://asgap.org.au/APOL33/mar04-1.html4|title=The Rainforest: Yes, It may be Copied|year=2004|accessdate=27 June 2010|work=Australian Plants online|publisher=Australian Native Plants Society (Australia)|author=Geo.
