Vegetative characteristics

The hairstalked sedge is a perennial herbaceous plant that reaches heights of 15 to 20, rarely up to 30 centimeters. It grows in dense grass and does not form runners . The stems are round and smooth. The gray-green to dark green, bare leaves are runny, 0.5 to 1 millimeter wide and a maximum of half as long as the stem. The basal leaf sheaths are pale or reddish brown and frayed.

Generative characteristics

The flowering period extends from May to July. The bracts have a longer, stem-encompassing leaf sheath. The lowest bract is the same length as the inflorescence. The hairstalked sedge is a variegated sedge. The terminal male spikelet has six to eight flowers and is surmounted by the top female spikelet. The two to four female spikelets are 5 to 15 millimeters long, contain six to ten loosely standing flowers and are on hair-thin, more than 1.5 centimeters long stems. The spikelets are drooping, especially when the fruit is ripe. The upper spikelets are brought closer together. The bracts are brown and have a white skin edge. There are three scars .

The chromosome number of the species is 2n = 54.

distribution

The hairstalked sedge is circumpolar in the subarctic and temperate zones of the northern hemisphere . It is a meridional-alpine to arctic floral element .

It occurs scattered in the Alps from the montane to the alpine altitude . In Central Europe it prefers altitudes between 800 m and 2500 m above sea level, but it rises almost to 3000 meters. In the Allgäu Alps, it rises in Bavaria at the Hochrappenkopf summit up to 2423 m above sea level.

It grows in soaking wet alpine flat and spring moors. In the Alps it inhabits stony and humus-rich mats , but it also goes on fine-grained gravel beds in rivers, in rinses , at hillside springs and on banks; it is seldom found on mats that dry out for a long time. It usually forms stocks. In Central Europe, locations outside the Alps are very rare, for example it used to be found on the Isar south of Munich . The population there is likely to have come about through flooding.

She loves lime. The hair-stalked sedge thrives best on soils that are rich in bases and, at least to a lesser extent, calcareous soils that should not be too compacted, but may be peaty if they are well drained. It is a character species of the association Caricion bicoloris-atrofuscae, but also occurs in associations of the associations Caricion davallianae or Seslerion.

Systematics

One can distinguish the following subspecies:

  • Carex capillaris subsp. capillaris : It occurs in the temperate zones of the northern hemisphere.
  • Carex capillaris subsp. fuscidula (VIKrecz. ex TVEgorova) Á.Löve & D.Löve : It occurs in the subarctic zones of the northern hemisphere.
