Genoplesium nudiscapum is a terrestrial, perennial, deciduous, herb with an underground tuber and a single thin leaf 60–80 mm (2–3 in) long and fused to the flowering stem with the free part up to 10 mm (0.4 in) long.

[2][3][4] Genoplesium nudiscapum was first formally described in 1853 by Joseph Dalton Hooker who gave it the name Prasophyllum nudiscapum and published the description in The botany of the Antarctic voyage of H.M. discovery ships Erebus and Terror.

[7] At that time, G. nudiscapum was described as occurring in New South Wales and Victoria but extinct in Tasmania, not having been seen there since 1852.

[9] The National Herbarium of New South Wales lists Genoplesium nudiscapum as occurring in that state.

It is threatened by land clearing, weed invasion and management and by inappropriate fire regimes.
