Scientific NameCommon NameSummary
Polypodium glycyrrhizaLicorice FernCommon fern of low elevations. Grows as epiphyte and on open rocks and cliffs. Expected throughout the region (FNA map), there are apparently only a few (geo-referenced) collections from Southeast Alaska. (Further searches in Arctos may reveal additional collections without coordinates.)
Polypodium hesperiumWestern PolypodyNot currently known from the region, but present on Haida Gwaii just to the south. There is a collection record from Prince William South as well, so this species could be expected to occur in Southeast Alaska.
Polypodium sibiricumSiberian PolypodyA single 2015 collection from Haines labeled as this species is the only report of this species, which appears to be more typically found in the interior in Alaska.
