Question
I found this on a small rocky rise in The Helderberg Escarpment NY. I think I've narrowed it down to a Polypodium species. Thank You
Answer
Dear Auntie, you have photographed a species of Polypodium (polypody), just as you thought. Based on the leaf blade outline and tips of the leaf lobes, it is most likely Polypodium virgnianum (rock polypody). This is a common, native species of fern.
