Craven & R.D.Edwards }}Eremaea beaufortioides is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a spreading shrub with oval to egg-shaped leaves, and orange flowers in spring. Flowers appear in groups of one to six on the ends of long branches formed in the previous year. It is commonly cultivated and is the most familiar of the eremaeas.[1] DescriptionEremaea beaufortioides is a spreading shrub growing to a height of {{convert|2.2|m|ft|sigfig=1}}. Its leaves are {{convert|2.9-5.6|mm|in|sigfig=1}} long, {{convert|1.4-4.2|mm|in|sigfig=1}} wide, flat, linear to broad egg-shaped and with up to 7 veins sometimes visible on the lower surface. There is variation in leaf size and shape between the three varieties of the species.[2][3]The flowers are orange-coloured and arranged in groups of up to six on the ends of the branches of the previous year's growth. There are 5 sepals and 5 petals {{convert|3.5-5.7|mm|in|sigfig=1}} long. The stamens, which give the flower its colour, are arranged in 5 bundles, each containing 34 to 48 stamens. Flowering occurs from September to December and is followed by fruits which are woody capsules. The capsules are more or less barrel-shaped, smooth and {{convert|8-11|mm|in|sigfig=1}} long and {{convert|2.8-6.1|mm|in|sigfig=1}} wide.[2] Taxonomy and namingEremaea beaufortioides was first formally described in 1867 by George Bentham in Flora Australiensis.[4][5] The specific epithet (beaufortioides) is presumably a reference to the similarity of this species to a species of Beaufortia since εἶδος (eîdos) is an Ancient Greek word meaning “form" or "likeness”.[2][6]There are three varieties:[2]
Distribution and habitatEremaea beaufortioides is found in the Irwin district[2] in the Avon Wheatbelt, Geraldton Sandplains, Swan Coastal Plain and Yalgoo biogeographic regions.[3] It grows in sand over laterite.[10]ConservationEremaea beaufortioides is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]Use in horticultureEremaea beaufortioides is an attractive species but although it is the hardiest of its genus, is difficult to grow in more humid areas unless grafted. It needs a sunny position and excellent drainage.[1][11]References1. ^1 {{cite web|title=Eremaea beaufortioides|url=http://anpsa.org.au/e-bea.html|publisher=Australian Native PlantsSociety Australia|accessdate=10 August 2015}} {{Taxonbar|from=Q15396896}}2. ^1 2 3 4 {{cite journal|last1=Hnatiuk|first1=Roger J.|title=A revision of the genus Eremaea (Myrtaceae)|journal=Nuytsia|date=1998|volume=9|issue=2|pages=167–169|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/202.pdf|accessdate=9 August 2015}} 3. ^1 2 {{cite web|title=Eremaea atala |url=https://florabase.dpaw.wa.gov.au/browse/profile/13962|publisher=FloraBase|accessdate=9 August 2015}} 4. ^{{cite web|title=Eremaea beaufortioides|url=https://biodiversity.org.au/boa/instance/apni/511223|publisher=APNI|accessdate=10 August 2015}} 5. ^{{cite book|last1=Bentham|first1=George|title=Flora Australiensis (Volume 3)|date=1867|publisher=Lovell Reeve and Co.|location=London|page=182|url=https://www.biodiversitylibrary.org/item/41807#page/190/mode/1up|accessdate=10 August 2015}} 6. ^{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page =483}} 7. ^{{cite web|title=Eremaea beaufortioides var. beaufortioides |url=https://florabase.dpaw.wa.gov.au/browse/profile/14098|publisher=FloraBase|accessdate=10 August 2015}} 8. ^{{cite web|title=Eremaea beaufortioides var. lachnostanthe |url=https://florabase.dpaw.wa.gov.au/browse/profile/14099|publisher=FloraBase|accessdate=10 August 2015}} 9. ^{{cite web|title=Eremaea beaufortioides var. microphylla |url=https://florabase.dpaw.wa.gov.au/browse/profile/14100|publisher=FloraBase|accessdate=10 August 2015}} 10. ^{{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=362}} 11. ^{{cite book|last1=Wrigley|first1=John W.|last2=Fagg|first2=Murray|title=Australian native plants : a manual for their propagation, cultivation and use in landscaping|date=1983|publisher=Collins|location=Sydney|isbn=0002165759|page=212|edition=2nd}} 5 : Eremaea (plant)|Myrtales of Australia|Flora of Western Australia|Plants described in 1867|Endemic flora of Western Australia |
