Taxonomy and naming
Hakea constablei was initially found in 1899 but the specimen was inadvertently stored with another Hakea. It was overlooked until 1950 when E.F. Constable collected the species near the Blue Mountains and brought it to the attention of botanists at the Sydney Herbarium. The species was first formally described by the botanist Lawrence Alexander Sidney Johnson in 1962 and published in Contributions from the New South Wales National Herbarium. The specific epithet honours Ernie Constable a former seed and plant collector for the Royal Botanic Gardens in Sydney. He collected mostly in New South Wales, including the type specimen for the species.
