This name without doubt was used for the genus before Cystopteris was, but the latter has been universally used by botanists for so long that it is very unlikely that Filix will ever be accepted. The Common Bladder Fern, Shaded rocks in almost any locality are likely to har- bour the common bladder fern (Cystopteris fragilis). It is fond of a niche in the cliff where its fronds may droop gracefully outward but also grows on the talus of broken rock at their bases and is often found in moist woods. In the extent of its distribution, it yields only to the.
