The felt-sedge ( Carex tomentosa ), also known as the felt- fruited sedge , is a member of the sour grass family (Cyperaceae) that grows scattered or rarely in Central Europe.

description

The felt sedge is a perennial, herbaceous plant that reaches heights of about 20 to 40 cm and has long runners . The stiff, upright, triangular stem is only coarsely hairy on top and has a black-red leaf sheath at the base. The stem leaves are gray-green, no more than 2 mm wide and have a triangular tip.

The lowest bract is formed like a leaf and towers over the spikelet. In the end it often sticks out horizontally. Usually the plant has one or two female spikelets about 0.5 to 1.5 cm long and one terminal male spikelet. These are cylindrical in shape, with short stems and a little distant. The fruity spikelets are whitish and brown piebald. The husks are pointed, red to light brown in color and have a green central nerve. The fruit sacs are 1.5 to 2 mm long, gray-brown in color, spherical-inverted-egg-shaped, almost beakless and covered with whitish tomentose hair.

It blooms mainly in May and June.

The number of chromosomes is 2n = 48.

Occurrence

Carex tomentosa occurs from southern Scandinavia and England to northern Italy, the Balkans and east to western Siberia and Central Asia. It is a temperate continental floral element. In Austria the species is absent-minded and endangered, while it is common in Switzerland. The felt sedge occurs in Germany only scattered in the central and southern areas. It is absent in northern Germany as well as in the low mountain ranges and in the Alps in larger areas.

It prefers to colonize wet meadows, ditch edges and light, somewhat damp deciduous forests. It barely rises above 1500 m in the Alps. In the Allgäu Alps, it barely exceeds the 800 meter altitude limit. The felt sedge needs summer-dry, but winter and spring moist, loamy or clayey, lime or base-rich, nitrogen-poor soil in a location that is not too shaded. It is a character species of the order Molinietalia, but also occurs in the Querco-Ulmetum of the Alno-Ulmion association.

The felt sedge does not tolerate fertilization very well and has therefore disappeared from grassland locations in many places. In humid littered meadows it was still found in large stocks in Central Europe around 1900 .
