Asplenium trichomanes
From Natural History of Southeast Alaska
Maidenhair Spleenwort (Asplenium trichomanes): Small evergreen fern with ovate pinnae which is expected to occur, but seems to be less common than A. viride. Two subspecies indicated in FNA, with ssp. trichomanes expected in the southern half of the region (FNA map) on acidic substrates, while ssp. quadrivalens (which occurs on limestone) not thought to occur in the region (FNA map). However, most collections from Southeast Alaska have been made from limestone, so further investigation may be warranted.
Local Notes
