CVU, EGL, EGU, GipP, Glep, Gold, HNF, HSF, NIS, OtP, SnM, VAlp, VVP, WaP, WPro. Widespread across Victoria in many habitats including open forest, heathland, scrubland and swamp margins.

Similar to C. ciliata, but that species has a greenish perianth with contrasting reddish labellum with shorter, sparser marginal hairs. Corunastylis arrecta has entirely dark purplish flowers, erect and more or less parallel lateral sepals and favours montane to subalpine habitats.
