description

Vegetative characteristics

The Fritsch sedge is a perennial herbaceous plant and reaches heights of 30 to 65 centimeters. The rhizome is short and compressed and does not creep like runners. The Fritsch sedge forms an eyrie . When weathered, a tuft of fibers develops from the lowest leaf sheaths . The leaves are 2 to 4 millimeters wide and bare on both sides.

Generative characteristics

The Fritsch sedge is one of the different years of sedges. Spikes are only in the upper half of the stem. There are two to three female ears, they are 6 to 12 millimeters long and spherical to ovoid. The tubes are obovate, 3 to 3.5 (to 4) millimeters long and short-haired to bald. The beak is always shorter than 0.5 millimeters and mostly truncated to weakly edged. She has three scars. The bracts are red to black brown. The top female ear does not protrude beyond the male ear. The male ear is (10 to) 15 to 20 (to 25) millimeters long, after the anthesis it is 3 to 4 (to 5) millimeters wide.

Their number of chromosomes is 2n = 30.

distribution

The Fritsch sedge has a sub-Mediterranean to temperate continental distribution. It occurs in France, Italy, Switzerland, Austria, the Czech Republic, Slovakia, Slovenia and Hungary; it is absent in Germany.

In Austria it occurs sparsely or rarely in the colline to submontane areas of Carinthia and Burgenland. It is considered endangered here. In Switzerland their occurrence is limited to Ticino . It is not considered to be endangered and is not protected in any canton.

It grows rarely, but gregariously, in light mixed deciduous forests on moderately dry, base-rich, but lime-free, moderately acidic, humus-rich loamy soils. She loves warmth. It is often a character species of the Galio-Carpinetum from the Carpinion association. It rarely grows in poor meadows.

Taxonomy

Carex fritschii was Anton Waisbecker 1895 based on discoveries at Güns in western Hungary firstdescribed .
