Stegostyla D.L.Jones & M.A.Clem. is a terrestrial genus in the Orchidaceae family created in 2001 by DL Jones, MA Clements, IK Sharma, and AM Mackenzie in a paper entitled A new classification of Caladenia R.Br. (Orchidaceae). This paper was followed by many others, some in support, some suggesting subgenera status, and others advocating keeping these species in Caladenia. This genus was never widely accepted and further taxonomic work by MA Clements, CG Howard CG1, and JT Miller published in 2015 did not support recognition of this genus as previously proposed. Information and photos of these species can be found on the Caladenia wiki page. Flowers have short broad segments with pink or white petals, a narrow leaf, and a lip with rows of free calli. It is very like the proposed genus Petalochilus except that the flowers are glandular on the outside and the dorsal sepal is curved forward over the column which does not have red bars.
