Cultivation and use of wood, shield and lady ferns
Cultivation and use of wood, shield, and lady ferns covers growing shade-garden Dryopteris and Athyrium ferns, notable cultivars like the Japanese painted fern, and male fern's historical use as a tapeworm remedy.
Cultivation and uses of maidenhairs and brakes
Cultivation and uses of maidenhairs and brakes describes growing Adiantum and Pteris ferns indoors and out, using Pteris vittata to extract arsenic from soil, and herbal uses.
Cultivation and uses of polypody ferns
The cultivation and uses of polypody ferns cover growing Polypodiaceae ferns such as mounted staghorn ferns, licorice fern, and resurrection ferns, and their traditional medicinal uses.

Cyatheaceae, the scaly tree fern family of the order Cyatheales, includes Alsophila, Cyathea, Gymnosphaera, and Sphaeropteris, about 700 tropical-mountain species with scaled trunks, x=69 chromosomes, and slow Jurassic-to-Cretaceous diversification.
Cyatheales

Cyrtomium falcatum
Cyrtomium falcatum (オニヤブソテツ), Japanese holly fern or Japanese netvein hollyfern, is an East Asian evergreen Dryopteridaceae fern with glossy falcate pinnae; it occurs as diploid sexual, triploid apogamous (n=123, 32 spores), and tetraploid sexual cytotypes and has escaped cultivation in North America and Europe.
Cystopteris
Cystopteris (bladder fern, brittle fern) is a cosmopolitan genus of about 20–26 temperate ferns in Cystopteridaceae, named for bladder-like indusia; sister to Acystopteris, with the widespread C. fragilis complex shaped by hybridization and allopolyploidy.

Desiccation tolerance in ferns
Desiccation tolerance in ferns is the ability of certain ferns and lycophytes to lose almost all cellular water, suspend metabolism, and resume normal function after rehydration.
