It is an erect, compact to spreading shrub with small, crowded leaves and orange-coloured flowers in early spring, followed by fruits with a rough outer surface. DescriptionEremaea brevifolia is an erect, densely foliaged to spreading shrub which sometimes grows to a height of {{convert|2.2|m|ft|sigfig=1}}. The leaves are {{convert|4.5-7.2|mm|in|sigfig=1}} long, {{convert|3.3-5.8|mm|in|sigfig=1}} wide, flat, crowded and so that they overlap each other. They are broadly egg-shaped with the narrower end towards the base and have 5 to 9 veins visible on the lower surface.[1][2]The flowers are orange-coloured, {{convert|8-10|mm|in|sigfig=1}} across and (usually) occur singly on the end of short branches which grew the previous year. There are 5 sepals which are densely hairy on the outside surface and 5 petals, {{convert|3.8-6.8|mm|in|sigfig=1}} long. The stamens are arranged in 5 bundles, each containing 50 to 70 stamens. Flowering occurs from August to October and is followed by fruits which are woody capsules. The capsules are {{convert|7|mm|in|sigfig=1}} long, cup-shaped and are rough or lumpy on the outer surface.[1][2] The leaves and fruits of this species are similar to those of Eremaea asterocarpa but the bracts surrounding the flowers are hairy.[1] Taxonomy and namingEremaea brevifolia was first formally described in 1923 by the Czech botanist Karel Domin in Vestnik Kralovske Ceske Spolecnosti Nauk, Trida Matematiko-Prirodevedecke.[3] It had previously been known as a variety - Eremaea fimbriata var. brevifolia Benth.[4] The specific epithet (brevifolia) is from the Latin brevis meaning "short"[5]{{rp|166}} and folium meaning "a leaf"[5]{{rp|466}} referring to the short leaves of this species compared to the subspecies now called Eremaea asterocarpa subsp. asterocarpa.[1]Distribution and habitatEremaea brevifolia occurs in the Irwin district[1] in the Geraldton Sandplains and Yalgoo biogeographic regions.[6] It grows in sand or laterite on plains and rock outcrops.[7]ConservationEremaea brevifolia is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[6]References1. ^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=200–202|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/202.pdf|accessdate=10 August 2015}} {{Taxonbar|from=Q15397158}}2. ^1 {{cite book|last1=Corrick|first1=Margaret G.|last2=Fuhrer|first2=Bruce A.|title=Wildflowers of Southern Western Australia|date=2009|publisher=Rosenberg Pub.|location=[Kenthurst, N.S.W.]|isbn=9781877058844|page=121|edition=3rd}} 3. ^{{cite web|title=Eremaea brevifolia|url=https://biodiversity.org.au/boa/instance/apni/511258|publisher=APNI|accessdate=10 August 2015}} 4. ^{{cite web|title=Eremaea fimbriata var. brevifolia|url=https://biodiversity.org.au/boa/instance/apni/511372|publisher=APNI|accessdate=10 August 2015}} 5. ^1 {{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.}} 6. ^1 {{cite web|title=Eremaea brevifolia |url=https://florabase.dpaw.wa.gov.au/browse/profile/5538|publisher=FloraBase|accessdate=10 August 2015}} 7. ^{{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}} 5 : Eremaea (plant)|Myrtales of Australia|Flora of Western Australia|Plants described in 1923|Endemic flora of Western Australia |
