Cystopteridaceae is a small, mainly temperate family occurring in both the northern and southern hemispheres. It is represented in New Zealand by one indigenous and one naturalised species. Cystopteris tasmanica is an indigenous species which occurs in montane and alpine areas of both islands, frequently on limestone or marble but also on greywacke and granite. It is widespread in the South Island, but confined to central parts of the North Island. It is found also in eastern Australia from New South Wales to Tasmania. Cystopteris fragilis is a naturalised species occurring mostly in urban areas from Auckland to Invercargill, which has been in New Zealand since the late 19th century. Species of Cystopteris can be recognised by their herbaceous, usually glabrous, pinnate to 3-pinnate laminae, by their hood-like indusia protecting the sori, and by their echinate spores.
Cystopteris has previously been included in Dryopteridaceae, Athyriaceae or Woodsiaceae, but on the basis of molecular evidence is now separated into a much smaller Cystopteridaceae.
