(2019) determined that specimens previously identified as P. macrocephalus are morphologically and ecologically distinct species, the now named Ptilotus xerophilus T.Hammer & R.W.Davis (arid central and western Australia) and Ptilotus psilorhachis T.Hammer & R.W.Davis (eastern Queensland).[1]
P. macrocephalus has cream-green coloured ovoid flower heads.[1] As with other green-flowered Ptilotus species (e.g. Ptilotus nobilis), they are thought to be predominantly pollinated by nocturnal moths.[1]
