It was first described in 1853 by Nikolai Turczaninow.[1][2] The specific epithet, dasyphyllus, comes from two Greek roots/words, dasys ("hairy") and phyllon ("leaf"), to give an adjective which describes the plant as being "hairy-leaved".[5]

It is declared "Not threatened" under Western Australian conservation laws.[4]
