Taxonomy and naming

Hakea pachyphylla was first formally described in 1827 by Curt Sprengel from an unpublished description by Franz Sieber in Systema Vegetabilium.[3][4] The specific epithet (pachyphylla) is derived from the Ancient Greek words pachys (παχύς) meaning "thick" and phyllon (φύλλον) meaning "leaf"[5] referring to the thickness of the leaves.[6]

Distribution and habitat

Hakea pachyphylla has a restricted distribution occurring only in the Mount Victoria, Leura, Newnes area in swamp or heath or mallee-heath, occasionally on sandstone.[7]
