  1. Very cool Michael!

    Just like my little fossil!

  2. This seems closer to Dennstaedtia producta than to our Ecuadorian D matthewsii ??

    Thanks for weighing in Benjamin. I appreciate your expertise on these plants. I can see why you say D. producta is a better match, but I am not entirely sure. The sori are not as long-stalked as those in D. producta, and I only see a single proliferous bud on the petiole. However, this collection may be a young leaf as you point out in your treatment in Nord. J. Bot. Do you know of indument characters that can help distinguish them?

    Here are links to the images of the pressed material at VT. Maybe you could take a look at these and see if you still think D. producta is the best name to apply.
