Isopogon teretifolius, commonly known as the nodding coneflower, is a small shrub of the family Proteaceae that is endemic to the southwest of Western Australia.
Taxonomy
Isopogon teretifolius was first described by Robert Brown in 1810. 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. Because Isopogon was based on Isopogon anemonifolius, and that species had already been placed by Richard Salisbury in the segregate genus Atylus in 1807, Kuntze revived the latter genus on the grounds of priority, and made the new combination Atylus teretifolius for this species. However, Kuntze's revisionary program was not accepted by the majority of botanists. Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905.
