CVU, DunT, HSF, OtP, VVP, Wim. Endemic to the basalt plains of south-western Victoria where it grows in grassland and grassy woodland on brown water-retentive clay loams.
A poorly known species that is critically endangered due to massive habitat loss.
This species is part of a complex of similar looking taxa, and has been confused in particular with the sympatric Prasophyllum sp. aff. occidentale E, which flowers earlier, has a broader labellum and often grows in clumps.
