CAUTION This group, H fastor, H nabucoi, H gourlieana and H macronectar are all fairly similar. I hope I have them separate in a correct fashion. H nabucoi is considered by Kew to be synomonous with H melvillei but I have left them separate for now. H fastor is also considered by Kew to be synomonous with H melvillei and so the photo for Habenaria melvillei Ridl. 1885 is what was considered to be H fastor, see above. I have to date not seen a plant labeled H melvillei so please use all of these species with caution!
