nom. illeg. as Brachychiton diversifolium R.Br. is cited in synonymy. There is conjecture on whether Bentham based his name on R.Brown's B. diversifolium, stating I have been unable to retain R. Brown's specific name, which had been previously applied by G. Don to the last species or was creating a new name with a new type. Base name for Brachychiton diversifolium var. caudatum (Benth.) Terracino; Clompanus caudatus (Benth.) Kuntze.
