Interesting, as I have also seen P. calidirupium on Isaacs Ridge.

What are the distinguishing features? I can go and take more photos. From photos on CNM the pinnae on P. falcata are less tapered than P. calidirupium and perhaps more of them.

Yes, that's right. The new photo definitely looks like P. falcata. Murphy's Law, of course, says they hybridise. P. calidirupium normally has many fewer pinnae, they get broader towards the base of the stipe, and rotate so that they are not co-planar with the pinna.
