Family: Cystopteridaceae

Group: Vascular Plant, Species

Scientific Name	Common Name	Summary
Cystopteris fragilis	Fragile Fern	Fairly Common fern typically found on wet cliffs. Quite a few collections of this species have been made from sites scattered throughout the region.
Cystopteris montana	Mountain Bladder Fern	Expected throughout the region (FNA map). Collections from the southern outer islands, Chichagof Island, one on Admiralty Island, and the mainland north of Haines. Seems like it may be associated with calcareous geology.
Gymnocarpium disjunctum	Pacific Oakfern	Common deciduous fern found in most productive forests, often in large colonies in riparian forest. Expected throughout the region, apparently only a few collections from both the south and north, but none in the central part (seems likely there are older collections still labeled G. dryopteris). Hybrids with G. dryopteris should be expected.
Gymnocarpium dryopteris	Western Oakfern	Expected and probably common throughout the region, some collections labeled as this species may be G. disjunctum. Hybrids with G. disjunctum should be expected.
