LoM, MuM, Wim. Endemic to Victoria where localised and known only from the Little Desert area and near Murtoa in riverine Eucalyptus largiflorens woodland, growing amongst ephemerals on sandy loam or cracking silty soils.
Most similar in appearance to P. maxima, but that species has broader rosette leaves, a broader labellum and favours different habitats.
Plants are subject to inundation during peak floods.
