EGL, EGU. Also NSW. In Victoria, currently known with certainty only from the upper Cann River valley in tall eucalypt forest with a sparse understorey on well-drained light brown clay loam.
Caladenia oreophila is similar to, and could be confused with, a few other eastern species; see C. montana, C. peisleyi, C. osmera and C. australis. It is also difficult to distinguish from the NSW species C. fitzgeraldii.
