It has a single hollow, onion-like leaf and up to fifty small, dull green to greenish-yellow flowers.

This onion orchid is common in soil pockets on granite outcrops in inland areas, mostly between Hyden and Balladonia.

[2][3][4][5] The desert mignonette orchid was first formally described in 1990 by Robert Bates who gave it the name Microtis media subsp.

[1] The specific epithet (eremicola) is Latin for "dweller of dry places", referring to the arid habitat of this species.

[2][3][4][7] Microtis eremicola is classified as "not threatened" by the Government of Western Australia Department of Parks and Wildlife.
