Taxonomy
Hakea clavata was first formally described in 1805 by Jacques Labillardière in Novae Hollandiae plantarum specimen. Labillardière may have made a type collection when at the Esperance region in December 1792.{{cite journal | first = Stephen | last = Hopper | author-link = Stephen Hopper | year = 2003 | title= South-western Australia, Cinderella of the world's temperate floristic regions 1 | journal = Curtis's Botanical Magazine | volume = 21 | issue = 2 | pages = 132–179 | doi = 10.1111/1467-8748.00380}} The specific epithet (clavata) is derived from the Latin word clava meaning "club",{{cite book|last1=Brown|first1=Roland Wilbur|title=The Composition of Scientific Words|date=1956|publisher=Smithsonian Institution Press|location=Washington, D.C.|page=231}} referring to the club-shape of the leaves.
Distribution
Coastal hakea is found on the mainland and on some of the islands between Israelite Bay and Esperance and a single population is known at Hopetoun to the west.{{cite web|url=http://www.flora.sa.gov.au/efsa/lucid/Hakea/key/Australian%20Hakea%20species/Media/Html/Hakea_clavata.htm|title=Hakea clavata|access-date=11 October 2018|work=Fact Sheet|publisher=Government of South Australia}} The range covers southeastern areas of the Southwest Botanical Province. The species grows in rocky sandy clay soils among granite outcrops and withstands salt laden winds.{{FloraBase|name=Hakea clavata Labill.|id=2141}}
