Taxonomy and naming
The sharp midge orchid was first formally described in 1858 by Joseph Dalton Hooker who gave it the name Prasophyllum despectans and published the description in Flora Antarctica.[4][5] In 1989, David Jones and Mark Clements changed the name to Genoplesium despectans[6] and in 2002 changed the name again to Corunastylis despectans.[7] The specific epithet (despectans) is derived from a Latin word meaning "to look down upon".[8]
Distribution and habitat
Genoplesium despectans grows in heath and heathy forest south from Wollongong in New South Wales and is common and widespread in Victoria. It also found in the south-east of South Australia and in Tasmania.[1][2][9]
