Scientific Name	Common Name	Summary
Asplenium adulterinum	Adulterated Spleenwort	Officially known only from Vancouver Island, the FNA account of this hybrid between Maidenhair Spleenwort (Asplenium trichomanes) and Asplenium trichomanes-ramosum suggests it could be expected elsewhere. A plant with the (apparently diagnostic, key-wise) character of partially brown rachis was photographed (but not collected) at Red Bluff Bay.
Asplenium trichomanes	Maidenhair Spleenwort	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.
Asplenium viride	Green Spleenwort	Expected throughout much of the region. Collections seem to primarily be from outer islands and the northern mainland. Seems to be scattered, though can be locally fairly common, especially in some limestone areas and also on the ultramafic bluffs at Red Bluff Bay.
