I think you are correct Aaron given the number of leaves in the basal rosette and the location, although at this time of year ther are many different Greenhood rosettes to be seen some of them Auitumn flowering species.
Many thanks for that Tony. Yeah this is a very well known colony that I keep an eye on, probably even the exact same plant that I usually find year after year in the same spot. There are a nice little clump of them here.
