DescriptionThe spreading non-lignotuberous shrub typically grows to a height of {{convert|1.5|to|3|m|ft|0}}.[1] The branchlets are densely covered in fine matted hairs. The terete evergreen leaves have five deep narrow grooves running through the entirety of their length. The leaves are glabrous on their face and have a length of {{convert|7|to|22|cm|in|1}} and a diameter of {{convert|1.2|to|1.5|mm|3}}.[2] It blooms from June to September and produces pink-purple flowers.[1] Each solitary axillary inflorescence has an umbelliform raceme and is grouped to form a long brush-like structure containing 60 to 80 flowers along the axil. The perianth is most often pink and less often is white. The pistil has a length of {{convert|10|to|12.5|mm|3|abbr=on}} with a sub-globular gland. Following flowering one to six stalked fruits will form per axil. Fruits have an obliquely elliptic shape that is sometimes curved with a length of {{convert|1.6|to|2.2|cm|in|2|abbr=on}} and a width of {{convert|0.8|to|1.1|cm|in|3|abbr=on}}. The light to dark brown seeds within have blackish patches. Each seed has an obliquely ovate to elliptic shape and a length of {{convert|11|to|14|mm|3|abbr=on}} and a width of {{convert|5|to|6|mm|3|abbr=on}} with a wing down both sides of the body.[2] TaxonomyThe species was first formally described by the botanist Brian Burtt in 1950 as part of the work Hooker's Icones Plantarum. Known synonyms are Hakea invaginata var. invaginata, Hakea sulcata var. intermedia and Hakea invaginata var. pachycarpa.[1] The specific epithet is taken from the Latin word invaginatus meaning enclose or fold in, referring to the longitudinally grooved leaves.[2] DistributionIt is endemic to an area in the Wheatbelt and Mid West regions of Western Australia from around Northampton in the north west to Mount Magnet in the northeast to around Merredin in the south and grows in sandy, loamy or gravelly soils.[2] It is often found on sandplains where it is part of shrubland communities that are dominated by species of Acacia or Melaleuca.[3] References1. ^{{cite web|url=https://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2903372#names|title=Hakea invaginata B.L.Burtt|accessdate=14 October 2018|work=Atlas of Living Australia|publisher=Global Biodiversity Information Facility}} {{Taxonbar|from=Q18081066}}2. ^1 2 {{FloraBase|name=Hakea invaginata|id=2167}} 3. ^1 2 3 {{cite web|url=http://www.flora.sa.gov.au/efsa/lucid/Hakea/key/Australian%20Hakea%20species/Media/Html/Hakea_invaginata.htm|title=Hakea invaginata|accessdate=14 October 2018|work=Electronic Flora of South Australia|publisher=Government of South Australia}} 3 : Hakea|Eudicots of Western Australia|Plants described in 1950 |
