This is not a typical B. nudum, but it looks to be in a dry area, so it may be a stunted form. The spores would tell the story. If there are spores under regular pinnae, definitely not B. nudum, which has fertile fronds very different from non-fertile ones. Reminds me a bit of Nephrolepis.

Am attempting to re-find this one to get pic of spores :/

The fertile fronds of B. nudum are quite different in appearance than the sterile fronds. There are no fertile fronds in that photo, if it is (likely) B. nudum.
