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 trilobus" for this species, as well as "a. tripartitus" for "i. tripartitus". 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.
