Since all the nearby plants are D. reflexum, these might also be D. reflexum rather than D. ampliatum. I might have initially given you a poor ID for this one
Lets wait and see. Nearby greenhoods have been identified as P. ampliata on iNaturalist (I've no idea who submitted it). Of my 3 most recent posted sightings, Ciarin has identified one as D. reflexum and the others as D. ampliatum. These were from yesterday's walk, on which I observed/photographed 10 specimens, most solitary stems but several as clusters. There seemed (to my less than perfect eyes) to be some minor variations in colour and significant ones in lateral sepal length, plus one specimen had two flowers on a single stem. I'm happy to await a consensus from our moderators!
