Wim, Gold, GGr. Also occurs SA. In Victoria, confined to the west between Edenhope, Nhill and Stawell where occurring in heathy woodland and box-ironbark forest on clayey and/or gravelly (often lateritic) soils.
Closely related to the South Australian Prasophyllum fitzgeraldii, but that species has a darker pink to reddish labellum lamina and the callus plate has a different structure.
True Prasophyllum fitzgeraldii, as represented by the type specimen from the Lofty Ranges, S.Aust., in not believed to occur in Victoria.
