Habit: Rhizome generally short-creeping. Leaf: stipe +- fleshy, often with few scales, base ×-section with 2 vascular strands; blade 2--4-pinnate, pinnae sides unequal, acroscopic pinnules more spreading, larger, more incised; veins free. Sporangia: sori round; indusia hood-like, arched over sorus, attached on side away from margin, often obscure in mature sori.
Species In Genus: +- 20 species: generally temperate, a few at high elevations in tropics. Etymology: (Greek: bladder fern, from indusia) Note: Often confused with Woodsia (pinnae sides equal; more fragmented indusia encircling sorus base). Sole sp. of Cystopteris in California highly polymorphic, may represent a sp. complex. Malformed spores produced by some pls, possibly indicative of hybridization, existence of different ploidal levels (numbers of chromosome sets).
