Corunastylis stephensonii D.L.Jones Genoplesium stephensonii, commonly known as Stephenson's midge orchid,[2] is a species of small terrestrial orchid that is endemic to the south-east of New South Wales.

There is a fleshy, dark red callus covering most of the labellum and extending nearly to its tip.

[3][4] In 2016, Julian Shaw changed the name to Genoplesium stephensonii in the Quarterly Supplement to the International Register of Orchid Hybrids (Sander's List)[5][6] and the name is accepted by Plants of the World Online.

[1] The specific epithet (stephensonii) honours the orchid enthusiast and conservationist, Alan W.

[3] Genoplesium stephensonii grows in shallow, well-drained soil over sandstone rock, and in sandy loam in heathy forest.
