Acianthus caudatus was first formally described in 1810 by Robert Brown and the description was published in Prodromus Florae Novae Hollandiae et Insulae Van Diemen.[4][5] The specific epithet (caudatus) is derived from the Latin word cauda meaning "tail".[6]

Distribution and habitat

Mayfly orchid grows among low shrubs in open forest south of the Manning River in New South Wales, through Victoria to the Eyre Peninsula in South Australia. It is also found in Tasmania.[2][3][7][8]
