Taxonomy and naming

The Mount Wilson midge orchid was first formally described in 1885 by Robert D. FitzGerald who gave it the name Prasophyllum eriochilum and published the description in Journal of Botany, British and Foreign. In 1989, David Jones and Mark Clements changed the name to Genoplesium eriochilum and in 2002, changed it again to Corunastylis eriochila but the last change is not accepted by the Australian Plant Census. The specific epithet (eriochilum) is derived from the Ancient Greek words ἔριον (erion) meaning "wool"Шаблон:Rp and χεῖλος (cheilos) meaning lip.Шаблон:Rp

Distribution and habitat

Genoplesium eriochilum is only known from the Blue Mountains between Blackheath, Mount Wilson and Mount Victoria, where it grows in heath with grasses and sedges.
