Taxonomy
Hakea preissii was first formally described by the botanist Carl Meissner in 1845 from a specimen collected in a forest near York. The description was published in Johann Georg Christian Lehmann's work Plantae Preissianae.[5][6][7] The specific epithet (preissii) honours Ludwig Preiss who collected plant specimens in Western Australia between 1838 and 1842.[4]
Distribution and habitat
Needle tree is endemic to an area in the Pilbara, Wheatbelt, Mid West and Goldfields-Esperance regions of Western Australia. It has a scattered distribution and is found as far north as Tom Price and south as Gnowangerup. It is found along the west coast and a little farther east than Kalgoorlie. The plant is found on plains and around the margins of salt marshes growing in sand, loam and sandy-clay soils.[1] It sometimes invades semi-arid pastoral land in Western Australia.[8]
