Has in the past been placed in genus Hieracidea (or Ieracidea) with F. novaeseelandiae, to which closely related. Race occidentalis often subsumed within nominate. Several additional races described, but much confusion owing to complexity of colour morphs, and studies suggest that most are invalid: thus melvillensis (from Melville I, off N Northern Territory), centralia (arid interior Australia) and tasmanicus (Tasmania) all included within nominate. Three subspecies recognized.

Subspecies and Distribution
