Taxonomy and naming.
"Gastrodia vescula" was first formally described in 1991 by David Jones from a specimen collected in a nature reserve near Mount Gambier in 1988. The description was published in "Australian Orchid Research". The specific epithet ("vescula") is a Latin word meaning "little" or "trifling" referring to the habit of this orchid.

The small potato orchid is only known from small area in the far southeast of South Australia and far western Victoria where it grows in dense, heathy forest.
