Genoplesium tenellum is a species of small terrestrial orchid that is endemic to eastern Australia.

There is a purple callus covering the base of the labellum and extending nearly to its tip.

[2][3] In 2016, Julian Shaw changed the name to Genoplesium tenellum in the Quarterly Supplement to the International Register of Orchid Hybrids (Sander's List)[4][5] and the name is accepted by Plants of the World Online.

[1] The specific epithet (tenellum) means "delicate' or "dainty", referring to the habit and appearance of this species.

[2] Genoplesium tenellum grows in woodland with shrubs and scattered trees around the edges of granite outcrops at altitudes of 710–1,000 m (2,330–3,280 ft).
