DescriptionThe spreading or low compact lignotuberous shrub typically grows to a height of {{convert|0.35|to|1.5|m|ft|0}}.[1] The branchlets have white flattened and matted fine hairs. The flat, rigid and evergreen leaves are twisted at the base and have a narrowly obovate shape and are {{convert|1.1|to|8.5|cm|in|2}} in length and {{convert|3|to|11|mm|in|3}} wide.[1] It blooms from June to November and produces white-cream-pink flowers.[1] Each axillary inflorescence is usually found arising from old wood and contains 6 to 16 flowers. The perianth is around {{convert|2|mm|in|3|abbr=on}} in length and covered with stiff white to pale brown hairs. The pistil has a length of {{convert|1.9|to|2.5|mm|in|3|abbr=on}}. Following flowering globular smooth or black-pusticulate fruit form that are {{convert|1.7|to|3.3|cm|in|2|abbr=on}} in length with about the same width. The seeds within have a wing around the body which is {{convert|12|to|20|mm|in|2}} long.[1] TaxonomyThe species was first formally described by the botanist Robert Brown in 1830 as part of the work Proteaceas Novas. Supplementum primum prodromi florae Novae Hollandiae. The only known synonym is Hakea leucadendron as described by Carl Meissner.[2] The specific epithet is from the Latin word crassatus meaning thickened. It is not known what is being referred to but it is thought it could be in reference to the stalk that the fruit is supported by.[1] DistributionThe plant is endemic throughout a large area of the Wheatbelt, Great Southern and Goldfields-Esperance regions[1] of Western Australia from Northampton in the north west to Ravensthorpe in the south east. It is found in open low heath communities[1] where it is found in sandy or gravelly soils around or over laterite or granite.[3] References1. ^1 2 3 {{cite web|url=http://www.flora.sa.gov.au/efsa/lucid/Hakea/key/Australian%20Hakea%20species/Media/Html/Hakea_incrassata.htm|title=Hakea incrassata|accessdate=14 October 2018|work=Electronic Flora of South Australia|publisher=Government of South Australia}} {{Taxonbar|from=Q18080657}}2. ^{{cite web|url=https://bie.ala.org.au/species/http://id.biodiversity.org.au/node/apni/2910680#names|title=Hakea incrassata R.Br.|accessdate=14 October 2018|work=Atlas of Living Australia|publisher=Global Biodiversity Information Facility}} 3. ^1 2 3 {{FloraBase|name=Hakea incrassata|id=2166}} 4 : Hakea|Eudicots of Western Australia|Plants described in 1830|Taxa named by Robert Brown |
