This looks more like P. falcata. The check is the presence of dark stalks that have lost their pinnae, and uniform width of pinnae. I can't quite tell from the photos. I should wander up to the trig point and have a look.

Thanks David I have also thought of it as falcata, but when I saw my photo I thought that the white hairs were distinctive of calidirupium and that they should be brown on falcata - am I looking at the wrong thing or have I my colours confused?

I think the two hybridise, so it's not a simple matter. If the lower pinnae are substantially broader than the middle and upper ones, I'd say P. calidirupium. If they are much the same, P. falcata.

Thanks for the tip David, I think the pinnae were much the same length but will check when next up there.
