description

Vegetative characteristics

The prickly sedge is a perennial herbaceous plant that rarely reaches heights of 7, usually 10 to 30 centimeters. It forms clumps with long runners . The smooth, round and thin stems are limp, curved and slightly protrude above the leaves. The leaves are less than 1 millimeter wide, bristle-shaped and curved. The basal sheaths are pale or reddish-brown and frayed.

Generative characteristics

The flowering period extends from May to August. The prickly sedge is a variegated sedge. There are one or two female spikelets that are 1 to 2 inches long, have few flowers and are practically sessile. There is a terminal male spikelet with a short stalk. The lowest bract has a short sheath and is shorter than the inflorescence , but longer than its spikelet. The bracts are dark red-brown and have a light central stripe and a white skin edge. There are two scars .

The fruit tube, which is brown when ripe, has short hairs and balding, with the beak 4.5 to 5.5 millimeters long, narrowly ovoid and gradually merges into the short, two-toothed beak. The fruit is longer than its bract.

The number of chromosomes is 2n = 36.

Occurrence

The prickly sedge thrives in the mountains of Central and Southern Europe. It is a submeridional-subalpine to temperate-subalpine, suboceanic floral element . In Central Europe they are found in the Limestone Alps ; otherwise it is very rare, but it sometimes forms smaller stocks.

In Central Europe it settles on sunny rocky slopes and rubble, on the one hand it extends into rock crevices that are poor in soil, on the other hand it extends into light, warm deciduous forests with open rock sections. It thrives mainly at altitudes of 700 to 2500 meters. They can also be found again and again on the gravel of the rivers that come from the Alps into the Alpine foothills . It grows in Germany in alpine stone lawns, on dry limestone rocks and on gravel alluvionen . It is rare in the Alps, otherwise it only occurs occasionally in the foreland (e.g. along the Isar). In the Allgäu Alps, it rises to altitudes of 2200 meters. It thrives in Androsacetum Helveticae and Potentilletum caulescentis from the Association Potentillion caulescentis and Caricetum company e from the Association Seslerion.

The prickly sedge thrives best on calcareous , stony-rocky subsoil that must be warm in summer and predominantly dry.
