[ID] This fern is classified as Dryopteris Filix-Mas in one old book, but isn't it a Christella Dentata?
I have a very old plant book, but in the fern section there's one that seems to have been cataloged incorrectly.
The plant is classified as Dryopteris Filix-Mas, but to me it looks much more like a Christella Dentata. What kind of fern is this in the photo?
