 Brown formally described and named the species in his 1810 On the Proteaceae of Jussieu . He did not identify a type specimen , but the one specimen in his collection has since been formally declared the lectotype for the species . He also did not explicitly give an etymology for the specific epithet , but it is accepted that the name derives from the Latin verticillatus ( " whorled " ) , in reference to the whorled leaf arrangement .
