[2][3][4][5] Microtis graniticola was first formally described in 1996 by Robert Bates from a specimen collected on Wave Rock near Hyden and the description was published in Journal of the Adelaide Botanic Garden.

[6] The specific epithet (graniticola) is Latin for "granite dweller", referring to the habitat preference of this species.

[4] Microtis graniticola grows in shallow soil pockets on large granite outcrops in arid areas between Balladonia and Mullewa.

Its distribution includes parts of the Avon Wheatbelt, Coolgardie, Geraldton Sandplains, Mallee, Murchison and Yalgoo biogeographic regions.

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