The Cryptostylis ovata is a terrestrial, perennial, deciduous, herb and is usually found growing in colonies, although not all plants will necessarily flower in the same year. The orchid has dark green leaves (that can be seen throughout the year). The leaves have a white central vein and the flower stem, which can grow up to 70 cm high, can have up to fifteen flowers. The flowers are a pale greenish colour, with a brownish-red labellum and a network of darker coloured veins.
