Glep, LoM, Wim. Also SA. Apart from an isolated occurrence near Portland, apparently confined to the Little Desert and Big Desert areas of western Victoria, often growing under mallee-scrub or Callitris gracilis (Slender Cypress-pine)/Eucalyptus leucoxylon (Yellow Gum) woodland, on well-drained sandy soil.

Plants from the Portland region are atypical in having a shorter, less protruding labellum.
