C. vitreus is a terrestrial, seasonal orchid, with solitary heart-shapedleaves having entire margins. The flowers, too, are solitary and their central part is mostly translucent. It has a height of 14 to 30 mm when flowering. It is very like C. walliae but differs in having a translucent labellum lamina with a dark maroon to purple band along the lateral margin. It differs from C. trilobus by having a broadly ovate flower. It flowers September to October and fruits from November to early January.
