It is a low, spreading shrub with small leaves, and orange-coloured flowers on the ends of the long branches which grew in the previous year. DescriptionEremaea ectadioclada is a low, spreading shrub growing to a height of {{convert|0.7|m|ft|sigfig=1}}. Its younger branches are densely covered with fine hairs. The leaves are {{convert|4-10|mm|in|sigfig=1}} long, {{convert|0.4-2.0|mm|in|sigfig=1}} wide, narrow egg-shaped, tapering to a point. There is a single vein, sometimes three veins visible on the lower surface.[1]The flowers are orange-coloured and occur singly or (rarely) in pairs, on the ends of the longer branches which grew in the previous year. There are 5 sepals which are densely covered with hairs on the outside surface and 5 petals {{convert|4-6|mm|in|sigfig=2}} long. The stamens, which give the flower its colour, are arranged in 5 bundles, each containing 16 to 36 stamens. Flowering occurs from July to November and is followed by fruits which are woody capsules. The capsules are {{convert|6.9-8.0|mm|in|sigfig=2}} long, rough and scaly on the outer surface and more or less barrel-shaped or cup-shaped. This species can be distinguished from other eremaeas by its rough, usually star-shaped fruit and narrow leaves.[1] Taxonomy and namingEremaea ectadioclada was first formally described in 1993 by Roger Hnatiuk in Nuytsia.[1][2] The specific epithet (ectadioclada) is from the Ancient Greek ektadios meaning "spreading" and klados meaning "branch" in reference to the growth form of this species.[1]Distribution and habitatEremaea ectadioclada is found in near-coastal areas of the Irwin district between Eneabba and Jurien Bay[1] in the Geraldton Sandplains biogeographic region.[3] It grows in sandy soil over laterite on sandplains.[4]ConservationEremaea ectadioclada is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]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=205–207|url=https://florabase.dpaw.wa.gov.au/science/nuytsia/202.pdf|accessdate=11 August 2015}} {{Taxonbar|from=Q15395711}}2. ^{{cite web|title=Eremaea ectadioclada|url=https://biodiversity.org.au/boa/instance/apni/568350|publisher=APNI|accessdate=11 August 2015}} 3. ^1 {{cite web|title=Eremaea ectadioclada |url=https://florabase.dpaw.wa.gov.au/browse/profile/13955|publisher=FloraBase|accessdate=11 August 2015}} 4. ^{{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 1993|Endemic flora of Western Australia |
