description

The lowest leaf sheaths are purple and fray like a network when torn open.
The leaves are short-haired on top.
Inflorescence with a ♂-ear above and several ♀-ears below.
Female ear with hairy tubes.
Tube with three stigmas and wrapper
The black-brown bracts are shallow and pointed at the front. The tube is clearly thickened at the marginal nerves.
Mountain sedge ( Carex montana )

The mountain sedge is a perennial herbaceous plant and reaches stature heights of 10 to 25, rarely up to 40 centimeters. With a strong "root stock" and clumpy growth it forms witch-ring-like stocks. The stems are stiff, thin and bluntly triangular and hang over when the fruit is ripe. The leaves are 1 to 2 mm wide, slightly hairy on the upper side, soft and finally longer than the stem. The leaf margin is very finely serrated and therefore appears rough. The basal sheaths are blood red and fray like a network.

The inflorescence is squat. It is a variegated sedge. The one to three female spikelets are densely flowered, rounded-oval, sessile and upright. The single male spikelet is dark brown and club-shaped. The lowest bract has no or a very short sheath and is dry-skinned. Often it has no blade or the blade has wide skin margins. The female spikelet belonging to it is sessile and is usually not surmounted by the bract. The bracts are black-violet to black-brown, the shape is obovate and pointed. They are not frayed and shorter than the fruit. The stylus has three scars . Flowering time is April to June.

The fruit, which is green-brown to dark-brown when ripe, is 3 to 4.5 millimeters long, narrow-oval, densely shaggy with hair and gradually merges into the beak.

The number of chromosomes is 2n = 38.

Occurrence

The mountain sedge is common from Europe to Siberia. It is a submeridional-montane to temperate, suboceanic flora element . It occurs in Central Europe from the collinen (hill country level) to the montane (mountain level) altitude level . It is absent in the Central European lowlands west of the Elbe and is rare east of it. In the low mountain ranges of Central Europe it occurs scattered on calcareous soil, where it is often stock-forming; it rises in the Alps to around the tree line. In the Allgäu Alps, it rises on the Vorderen Üntschenalp near Schoppernau in Vorarlberg up to 1730 m above sea level.

It grows in warm deciduous forests, bushes and semi-arid grasslands . In lower altitudes it often occurs in the Carici-Fagetum and in the Galio-Carpinetum, in higher altitudes more in the Mesobromion or in the company of Sesleria albicans .

It is limestone and a (lime) clay pointer . The mountain sedge grows on moderately alkaline and often calcareous , dry clay soils mixed with gauze or humus in a climate-favorable location.
