description

Vegetative characteristics

The bank sedge is a perennial herbaceous plant that reaches heights of 40 to 120, rarely up to 200 centimeters. It forms long runners . The upright stems are sharp triangular and rough in the upper area. The gray-green leaves are 5 to 20, rarely up to 30 millimeters wide, flat, but with a central groove and rough at the edge. The ligule is flat rounded. The basal leaf sheaths are brown and not reticulated, but latticed. The remaining leaf sheaths are torn at the ends, but not latticed.

Female spikelets of the bank sedge

Generative characteristics

The bank sedge is a variegated sedge. There are three to six male spikelets that are thick and densely flowered. The three to five female spikelets are 8 to 12 millimeters wide and club-shaped. The lower ones have a long stem and often nod. Their bracts have a short sheath and are longer than the inflorescence . The bracts are lanceolate and have a hair tip. they are light purple-brown with green stripes and are about the same length as the fruit. The stylus has three scars .

The olive-green to gray-brown, bald fruit is 5 to 7 millimeters long, indistinctly veined and puffy. The fruit has no longitudinal furrows and gradually merges into the short, two-toothed beak.

The number of chromosomes is 2n = 72.

distribution

The bank sedge is common from Europe to Central Asia and southern South America. In Europe it is a meridional to temperate, oceanic floral element . It occurs scattered in the plains .

In Central Europe , it is particularly absent in landscapes with a harsh climate in larger areas. Overall, it is rare in Central Europe. At its locations, it is usually an inventory building. It only rises in the warmest alpine valleys at altitudes of a little over 1000 meters.

It settles in Großseggenrieden and in swamp forests, for example alder quarries. It grows in ditches, wet meadows, silting areas and on banks. The bank sedge is a character species of the Caricetum ripariae from the Magnocaricion association, but also occurs in communities of the Alnion.

The bank sedge thrives best on base-rich, often calcareous , peaty or clayey soils , which must be wet and may be temporarily flooded. It is sensitive to cold and can tolerate shade.

Systematics

One can distinguish the following subspecies:

  • Carex riparia subsp. chilensis (Brongn.) Kük. : It occurs in South America in Argentina, Chile, Uruguay and Paraguay.
  • Carex riparia subsp. riparia : It occurs from Europe to Central Asia.

use

The bank sedge was previously valued as a source of litter ; however, it was already rare in Central Europe at that time .
