Genoplesium morrisii is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf 200–250 mm (8–10 in) long and fused to the flowering stem with the free part 10–22 mm (0.4–0.9 in) long.

[2][3][4] The bearded midge orchid was first formally described in 1931 by William Henry Nicholls who gave it the name Prasophyllum morrisii and published the description in The Victorian Naturalist.

[6] Genoplesium morrisii grows in forest, woodland and heath and is widespread and common in the southern half of Victoria.

[2][3][9] Corunastylis morrisii is classed as "Endangered" under the Tasmanian Threatened Species Protection Act 1995.

It is only known from a few near-coastal areas in the north and south where fewer than 100 mature plants are thought to survive.
