This species was first described in 1839 by John Lindley who gave it the name Trichinium manglesii in Edwards's Botanical Register, from specimens collected in the Swan River Colony. In 1868, Ferdinand von Mueller transferred the species to Ptilotus as P. manglesii in his Fragmenta Phytographiae Australiae. The specific epithet honours "Caption James Mangles, R.N.".
