Taxonomy and naming

The lemon scented midge orchid was first formally described in 1991 by David Jones and Mark Clements who gave it the name Genoplesium citriodorum and published the description in Australian Orchid Research. In 2002, Jones and Clements changed the name to Corunastylis citriodora but the change is not accepted by the Australian Plant Census. The specific epithet (citriodorum) is derived from the Latin words citrea meaning "the citron-tree"Шаблон:Rp and odor meaning "smell",Шаблон:Rp referring to the strongly lemon-scented flowers.

Distribution and habitat

Genoplesium citriodorum is only known from the Blue Mountains at heights of Шаблон:Convert where it grows under shrubs in shallow soil over sandstone and sometimes in permanently wet areas.
