Isopogon divergens

The species was first formally described by botanist Robert Brown in 1830, based on material collected by Charles Fraser along the Swan River.[2] In 1891, German botanist Otto Kuntze published Revisio generum plantarum, his response to what he perceived as a lack of method in existing nomenclatural practice.[3] Because Isopogon was based on Isopogon anemonifolius,[4] and that species had already been placed by Richard Salisbury in the segregate genus Atylus in 1807,[5] Kuntze revived the latter genus on the grounds of priority, and made the new combination Atylus divergens for this species.[6] However, Kuntze's revisionary program was not accepted by the majority of botanists.[3] Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905.[7]
