I suspect this of being interjectum! Plausible?

Emerging fronds of rock polypody ( virginianum) display the circinate vernation characteristic of many ferns; i.e. their leaves begin as a tight coil, which unfurls from base to tip as the leaf matures (vernation=leaf arrangement in bud).

Echoes of ancient ? virginianum is an native to eNA, but its diploid progenitors (P. appalachianum & sibiricum) are now disjunct.. suspected they overlapped in past (Ice Ages?) yielding this fern! See Haufler 1995 in Syst Bot

Polypodium cambricum looks as fresh as a daisy at this time of year and will do throughout the winter. Tolerant of dry shade once established.

Polypodiums get their new fronds in summer, so they still look lush and leafy at this time of year when everything else is going a bit brown.

Winter can be a great time to observe evergreen ferns, as their green leaves stand out with the deciduous leaves fallen and amidst the snow. The aptly named rock polypody () likes ledges and boulders, most often in less than full sun.
