Calothamnus quadrifidus subsp. petraeus is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is similar to other subspecies of Calothamnus quadrifidus except that its leaves are linear and somewhat rough and scaly and the stamen bundles are relatively long. (Subspecies seminudus is similar to petraeus but has smaller fruit.)
