Oh what a wonderful find! It has been a few year since this species has been recorded in the ACT. A NSW survey indicated that, like the ACT, the populations of this species in southern NSW have diminished over the past decade or so. This sighting provides hope that Namadgi may contain more populations of this threatened species.
After I found these plants I had a look on CNM and saw there was a record in the swamp a little further north so I assumed they were doing OK in the area. Didn’t realise the species hasn’t been seen for a while. My colleague saw some near Tharwa last year. I will send you a DM later when he has given me the details @gregbaines .
