DescriptionThe shrub or tree typically grows to a height of {{convert|0.6|to|4|m|ft|0}}.[1] The branches are glabrous as are the thin evergreen leaves which have a linear to narrowly elliptic shape and are {{convert|2|to|8|cm|in|1}} in length with a width of {{convert|2|to|7|mm|in|3}}.[1] It blooms from January to May or October to December and produces cream-white flowers.[1] Each simple inflorescence contain 16 to 20 flowers with a white glabrous perianth that is {{convert|3|to|5|mm|in|3|abbr=on}} in length. The rugose to black-pusticulate fruits have an obliquely obovate shape with a curved apex. Each fruit is {{convert|1.5|to|2.5|cm|in|2|abbr=on}} in length with a width of {{convert|0.7|to|1|mm|in|3|abbr=on}} and have {{convert|2|to|4|mm|in|3|abbr=on}} long horns. The seeds within have an obliquely obovate shape and a wing down one side.[1] TaxonomyThe species was first formally described by the botanist Robert Brown in 1810 as part of the work On the natural order of plants called Proteaceae as published in the Transactions of the Linnean Society of London.[2] The specific epithet is taken from the Latin word linearis meaning linear, which refers to the shape of the leaves.[1] It can be confused with Hakea varia and related species.[1] DistributionIt is endemic to an area along the coast in the South West and Great Southern regions of Western Australia between Busselton in the west, Wagin to the north and Albany to the south. It is often found among granite outcrops and seasonally damp areas like swamps growing in sandy or sandy-clay soils[3] and is usually part of sandy heathland or Eucalyptus woodland communitities.[1] References1. ^1 2 3 4 {{cite web|url=http://www.flora.sa.gov.au/efsa/lucid/Hakea/key/Australian%20Hakea%20species/Media/Html/Hakea_linearis.htm|title=Hakea linearis|accessdate=15 October 2018|work=Electronic flora of South Australia|publisher=Government of South Australia}} {{Taxonbar|from=Q18079674}}2. ^{{cit web|url=https://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2903955#names|title=Hakea linearis R.Br.|accessdate=15 October 2018|work=Atlas of Living Australia|publisher=Global Biodiversity Information Facility}} 3. ^1 2 {{FloraBase|name=Hakea linearis|id=2174}} 4 : Hakea|Eudicots of Western Australia|Plants described in 1810|Taxa named by Robert Brown |
