The shape and one or two pale unfurling fronds remind me a bit of C. distans. Did the undersides of the pinnae have pale hair, and especially the unfurling frond tips? I can't quite tell from the photo.
I don't believe that pale hair is visible on the undersides. A quick look at my other photos doesn't help, although I will upload another 'nearby' image that may assist. I will double check in my next visit.
