Polypodium cambricum, a common fern in northern Spain, but rare here, in the mediterranean dry east where I live.
The leaf surface is very reflective. To avoid reflections, the illuminantion was done whith cross polarized light, both polarizers at the end of two fiber optic light guides and the analyzer behind the macro lens.
First image of inmature sorus, I like its transparency, second one of mature sorus. I was surprised to see the epidermical cells and stoma at this moderate magnification.

Many thaks to all the skilled photographers in this forums, in special to Charles Krebs. This is the best school of macro and micro photography I can imagine.

Pau,
You reminded me that I left an unfinished stack of an almost identical scene of a California Polypody, which I've now finished. I don't recall all the specifics but you can see I had some pretty bad highlights to deal with, using no polarized light.
