Labellum broadly elliptic to ovate-elliptic, c. 3 mm long, 1.8 mm wide, the margins with numerous, coarse, spreading cilia c. 0.8 mm long; callus narrowly ovate, extending three-quarters of distance to the labellum apex.

EGU, HNF, HSF, MonT, NIS, SnM, VAlp. Widespread and sometimes locally common in montane and subalpine areas of eastern Victoria, mostly in grassland and Snow Gum woodland.

Similar to C. archeri, but with outward facing flowers with stiffly erect lateral sepals which remain parallel or diverge only slightly.

Flowering may be enhanced by fires during the previous summer.
