I bought this fern yesterday and it came with no tag and it was the only one of its kind. I asked the nursery which it was and, after looking in a book, they said it was Dryopteris ludoviciana (southern shield fern). I was hoping to get a second opinion to either confirm that or offer another suggestion. Let me know if you need any other angles than the ones pictured.

It sure seems to match the photos of Dryopteris ludoviciana available online.
A photo of the entire frond shown in photo 7 might be useful in order to determine whether it has the following identifying features:
- Fertile and sterile pinnae are dissimilar in that fertile pinnae are narrower and more widely spaced
- Fertile pinnae are found in the upper 1/2 of the frond with sterile pinnae in the lower 1/2 (from http://www.wlf.louisiana.gov/s...)

The frond in the 7th photo is also the frond in the 4th photo. I'll have to look more but it does appear that the fertile pinnae are more widely spaced than the sterile. That and the fertile pinnae are in the top half of that one frond pictured.
