Ferns.....they remain a mystery to me. But now I do notice some differences between them.

Species according to other people.

Woodwardia virginica:

[ID: A photo of a Virginian chainfern frond with more behind it. The fern is dark green, with rounded, deeply-toothed leaves. The central stem is thin, and appears dark in this photo. End ID.]

Woodwardia areolata:

[ID: A photo of a netted chain fern frond. It is light green, with large, almost smooth lobes. The central stem is bordered by a thin leafy area, making it flat and wide rather than thin and round. End ID.]

Osmundastrum cinnamomeum:

[ID: A photo of a cinnamon fern frond, with a green butterfly net nearby. These leaves are dark green, and have rounded but shallow teeth. The central stem is very thin. End ID.]
