Or possibly D. decurvum? The labellum doesn't look very curved and the base of the flower is fairly straight, not bulging.

Thanks for your suggestion Cath. I thought that the flowers were much bigger than the usual decurvum, I should've taken a photo with a size indicator. But your observation on the base of the flower and labellum do fit with decurvum. Are they known to form small colonies? There were about eight plants in the one patch, two in another. I've only seen them solitary previously.

Hi Shoko. Orchids of the ACT mentions decurvum growing in small groups and Wild Orchids of Victoria talks about extensive colonies! I can't comment on the size, but perhaps plants might grow a bit larger in this season's mild and wetter conditions?

Yes perhaps some would be larger with a favourable season. I'm happy with your suggestion Cath, thanks!

They seem to form much smaller flowering colonies than the other greenhoods, but I have seen a few colonies with several flowering plants.

Thanks for your comment Matt, I guess I've seen my first colony of happy decurvums now :)

I believe these are D. decurvum as the labellum is not prominent or curved enough for D. aestivum. I am seeing considerable size difference in this species this year. Some quite tall with others much shorter.

Thanks for your comments Derek, good to know you've been seeing variation in size with this species.
