@michaelb Jean Egan saw this same plant last week, and her conclusion was that it is P Keltonii, not Bagoense. The flowers have too much colour and the flowers smell, which is typical of Keltonii, she said.
@Marchien P. keltonii was my first impression of this plant but ultimately decided the shape of the flowers was a better fit for bagoense. I also note in Jean's book she says for both species they are fragrant, however in Lachlan Copeland's guide to orchids of NSW and the ACT he says for both species "usually unscented." Do you have some other photos you can upload? Otherwise I will ask Jean if she has any.
I have gone through my photos, but don't have any. I will check with other members, if you can check with Jean? A small group from the native plant society was at the property last week, Jean Egan was there as well.
