with an underground tuber and a single, erect, narrow linear, hairy leaf, long and wide. Usually only one greenish yellow and red flower, long and wide is borne on a stalk tall. The petals are downswept and relatively short whilst the lateral sepals are relatively wide near the base but narrow to a thread-like end covered with reddish glandular hairs. The labellum is greenish-yellow with red markings, a red tip and smooth edges. There is a dense, narrow band of short, red-tipped calli along the centre line of the labellum. Flowering occurs from August to October. This species is similar to the short sepalled spider orchid '' C. brevisura'' and the puppet orchid '' C. incrassata'' but is distinguished from them by its longer sepals and narrower band of calli.
