It was first published in 1838 by Stephan Endlicher, based on material collected by Charles von Hügel from the vicinity of King George Sound. It has since had a fairly involved taxonomic history. In 1839, John Lindley published a purported new species, C. sclerophyllum, but this has since been demoted to a subspecies of C. stoechadis. In 1848, Carl Meissner published C. canaliculatum; this was demoted to a variety of C. stoechadis by George Bentham in 1870, but has since between restored to specific rank. In 1919, Michel Gandoger published two new species, C. elegantulum and C. proximum, but both of these have since been found to be synonymous with C. stoechadis. In each case, the current status was designated by Eleanor Bennett's 1995 treatment of Conospermum for the Flora of Australia series of monographs.
