Class Polypodiopsida CRONQUIST, TAKHT. et W.ZIMM., 1966

R e m a r k s. Ferns are represented in the Torres Vedras mesofossil by salvinealean megaspores with their associated microspores, as well as vegetative and fertile portions of various other ferns, including tiny fiddleheads, fragments of pinnules and sporangia with microspores. In this section, we briefly describe the megaspores and microspores. The vegetative remains provide evidence of additional fern diversity, but are not especially common and are too fragmentary for more precise systematic determination. Microspores recovered in sporangia or in clumps are probably mostly from ferns, but some may represent other spore-bearing plants such as lycopodiopsids and bryophytes.
