description
The lawn sedge grows perennial herbaceous plants and reaches heights of 15 to 60 centimeters. It forms dense clumps without elongated runners . The stems are slender, thin and sharp triangular. The leaves are 2 to 3 mm wide, light green and rigid. They are the same length as the stem. The ligule is significantly higher than it is wide. The basal sheaths are purple-red, spideless and frayed, fine-meshed, reticulated.
The flowering period extends from April to May. There is a male spikelet. Of the one to three female spikelets, the bottom 1 to 2 centimeters long and short stalked, the top is sessile. The bracts of the female flowers are black with a reddish brown central stripe and pointed to the maximum. The stylus has two scars .
The bald fruit is round with a diameter of 2 millimeters, shows no veins and is unbeaked.
The number of chromosomes is 2n = 78 or 80.
Occurrence
The turf sedge is common in the temperate zones of Eurasia . It is a submeridional montane to boreal continental flora element . It thrives in Central Europe in wet flat moor meadows and alder quarries on base-rich, but lime-free peat soils . In Germany it occurs scattered in the north, east and south and populates at most the submontane altitude level up to altitudes of 1000 meters. It is a character species of the Caricetum cespitosae from the Magnocaricion association, but also occurs in societies of the Caricion lasiocarpae or Alnion associations.
