Went back and found my previously sighted Chiloglottis open. Absolutely beautiful, though sadly, definitely alone. Combed all around it and couldn't find any others. Seems to match up with C reflexa using the plantnet key and L Copeland's recent book, but possibly C sylvestris? Lacking spots on dorsal sepal which seem to be on all iNaturalist sightings of C sylvestris (but which are not mentioned on PlantNet nor the book).
