P. uroglossum no longer exists in NSW taxonomy as it is considered to be the same thing as P. fuscum. I've advised Council admin to update the taxonomy to reflect this. I can't ID this one to species level, at least not reliably, as I'd need a close-up of the flower to see all of the components needed for a good ID. Doesn't look like P. appendiculatum and the location and potentially habitat is more aligned with P. fuscum.

I have already asked Tobias to look at this. David Jones most recent book appears to not agree with that and he still lists these species and for this area.

Thanks DerekC, not surprising - orchid taxonomy! But for regulatory purposes, we're stuck with having to use the taxonomy that is current in NSW. It may yet change again... I gather (and I'm very deliberately not an expert on NSW orchid taxonomy) that David's work tends to be viewed as being at the 'splitter' end of the spectrum and that it has not been supported by some reviews, including molecular assessments. But again, that's out of my league. I think that genetics will be the arbiter in such debates, especially now that it is vastly more robust and cheaper, so there is a lot more work being done, in part to resolve issues like this. I'd also note that just because PlantNet takes a particular stance on a species, doesn't mean that it is current or otherwise accurate, not least because that website isn't properly resourced (compare it with VicFlora). I've just put the pics and the collector's additional information to the former DPIE AO for the species, and he said it looks likely for fuscum but recommended review by Lachlan Copeland and Gavin Phillips, so I've sent it on to them.

Lachlan deemed it P. appendiculatum and noted that he has seen it to be common where the observer reported this sighting. He said that P. fuscum s.s. (in the strict sense) is extremely rare and that he recently saw all three of the known plants in Wollondilly Shire.

Thanks for asking Lachlan, he'll be the one who knows best here. I've not seen either species

Thanks on Lacklan's advice I will change it, I had added both but chosen the other.

Gavin Phillips just replied separately with the same ID, so I think that's a definite answer now.
