I am a postdoc at the University of Gothenburg, Sweden. I am interested in fern and lycophyte diversity, especially in the American tropics.

It is amazing! This individual is not exindusiate that is different from the common sense of the diagnostic character of this species. How to distinguish this species from striatum? I’m a little confused.
Good points, and the two species are close. In my understanding of D. lindbergii, it can have a rudimentary or non-persistent indusium.
The other differences I note and why I think this is D. lindbergii are that the lamina is chartaceous (vs. firmly herbaceous), the lamina dried a very dark color (vs. bright green), and that D. striatum tends to have slightly falcately ascending pinnae, which this plant does not have.

Hi Ran,

I could definitely be wrong, though.
