features
The mountain bladder fern reaches heights of 15 to 45 centimeters. It has a long, creeping rhizome , so the fronds are spaced apart. The fronds are double to fourfold pinnate, their blade is shorter than the petiole . The outline is triangular to ovoid. The rachis is covered with fine glands. The veil (indusium) is almost bare. The edge of the chaff scales are covered with glands. The spores ripen in July and August.

Occurrence
The mountain bladder fern is common in the northern hemisphere in Eurasia and North America . In Europe it occurs in the mountains, northwards to Norway , southwards to the Pyrenees , the Apennines and Yugoslavia , the Caucasus and up to the Alps at altitudes of up to 2400 meters. In the Allgäu Alps, it rises in the Tyrolean part on the ridge between Grubachspitze and Sattelkarspitze near Hinterhornbach up to 2100 meters above sea level.
The mountain bladder fern occurs in Central Europe, especially in the Alps, scattered at higher altitudes. The mountain bladder fern occurs in Baden-Württemberg and Bavaria , in all of Austria with the exception of Vienna and Burgenland, and in Switzerland . It is rare in the Swabian Alb, but is scattered in the Alps. It grows on moist, shady limestone rocks and on limestone rubble in mountain forests. It occurs in the montane to subalpine altitude range and gets its name from this altitude distribution.
Cystopteris montana is an association character species of the Cystopteridetum montanae from the association Petasition paradoxi and also occurs in the Asplenio-Piceetum from the association Piceion abietis.
