## Taxonomy and naming

Patersonia macrantha was first described in 1846 by George Bentham in Flora Australiensis. Bentham recorded that the type specimens were collected in the Darling Range by Alexander Collie. However, the sheet bearing the type specimens in the Kew Herbarium was inscribed "Armstrong, Port Essington" in W.J. Hooker's handwriting, later crossed out by Bentham with a note "probably Darling Range, Collie (the loose scape was with the Darling Range occidentalis)". The specific epithet (macrantha) means "large-flowered".
