I've lost my confidence in being able to tell the species of Pellaea apart, hopefully you can set me right David. These are plants from the same location as the earlier Pellaea postings from Red Hill

Not simple, but the short broad pinnae on some fronds indicate Pellaea calidirupium, Pellaea calidirupium and falcata (and also Cheilanthes) in the ACT are difficult, and probably hybridise.

Thanks David

Another indicator for P. calidirupium (in vivo, not pressed) is that many of the pinna blades are angled to the plane of the frond, whereas with P. falcata, the pinnae and frond are in the same plane.
