Orchids in this genus are distinguished from those in the similar Caladenia by having a glabrous leaf and a densely woolly labellum.

Their common name alludes to their prominent ear-like lateral sepals.Orchids in the genus Eriochilus are terrestrial, perennial, deciduous, sympodial herbs usually with a few inconspicuous, fine roots and a roughly spherical, succulent tuber.

The sexual parts of the flower are fused to the column, which is erect, short, weakly curved and has narrow, wing-like structures.

[2][4][5][6][7] The genus Eriochilus was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae.

[2] Ten species of bunny orchids occur in Western Australia where they are found in a range of habitats from areas that are swampy in winter to dry inland woodlands.
