A very light coloured specimen that I thought would be interesting to add.

Not sure, but I have suggested this might be S. australis rather than S. alticola given the relatively low elevation (c715m) and the flower segments are not very widely spread.

I guess my comment would apply to other sightings from the same location. My difficulty is that I can't easily tell them apart myself and I wonder if there are in fact two species. I have not had a satisfactory answer when I have raised this with the "experts", except that S. alticola is found in montane and subalpine areas, which i don't think could be said to apply to Gundaroo. Perhaps others have a view.

D.Jones lists S.alticola as occurring between 700 and 1000 so not immediately ruled out? Other than that this is very difficult indeed. If I use this image in Vicflora database
https://vicflora.rbg.vic.gov.au/flora/taxon/d3b2098a-50dd-46cc-b70b-d030baed68a7#&gid=1&pid=5 as typical for the tubular labellum I don't think we observe that here. Every plant seems to have at least some flowers that are much more open than that at every stage, as the flowering moves up the spiral. But I've really only started looking into this today...

I contacted David Jones and this is what he had to say: "Looks like S. australis to me Tony. It also occurs on Black mountain. Recognised by the narrower more or less tubular flowers. S. alticola has more widely opening flowers with a broader flared labellum."
