illustration

The fox sedge grows as a deciduous, perennial herbaceous plant . The leaves are simple. It grows clumpy. Their spikelets are male at the tip, and the fruit is pointed in a two-toothed beak. Female flowers have two stigmas. The plant is between 30 and 100 cm high and has 4–10 cm wide, more or less upright leaves that are keeled to a point. The fox sedge is a sedge of the same age.

The number of chromosomes is 2n = 68.

Differentiation of similar species

The fox sedge differs from the similar false fox sedge ( Carex otrubae ) mainly in the winged stem and the beak of the rust-brown colored tubes, which are cut significantly deeper on the curved side than on the flat side. Further characteristic features are the flat-angled ligule ; the leaf sheaths , which have broad, black-brown nerves and the short bracts of the inflorescence, which have brown auricles at the base.

ecology

The Fuchs sedge is a helomorphic, scleromorphic hemicryptophyte .

The pollination is carried by the wind. The diaspores spread by the wind, Velcro spreading or self-spreading.

Occurrence and endangerment

The fox sedge is common in Eurasia , it occurs from Europe to northwestern China. In Central Europe it occurs scattered, and it forms smaller stocks here and there. It has its main occurrence on the edge of nutrient-rich waters and also populates banks, ditches, wet meadows, wet meadows , reeds and large sedge beds . The fox sedge is the characteristic of the plant community (association) of the fox sedge (Caricetum vulpinae).

The fox sedge colonizes base-rich, but not necessarily calcareous , moist or even wet soils . She avoids full shade. It rises in the mountains to altitudes of around 1000 meters.

The fox sedge was classified as endangered in Germany's 1996 Red List of Endangered Plant Species.
