Its grass-green, about 2 to 3 mm wide, double-folded leaves run into a characteristic long, triangular point. The red-brown leaf sheaths have red-brown nerve lines on the inside on the back, which form fibers when decomposed.

The flowering period extends from April to the end of May. The up to 2 centimeters long inflorescence is composed of a terminal male spikelet pointed at the end and two to three female spikelets below. The husks have no noticeable whitish skin edge. The tubes are densely or briefly hairy and almost spherical.

The number of chromosomes is 2n = 18.

Occurrence

The distribution area of the pill-sedge is limited to Europe and Macaronesia . It is partially absent in the Arctic and the Mediterranean.

The pill sedge mostly colonizes fresh to moderately dry sandy and silicate grasslands , light deciduous forests, fresh forest edges, dwarf shrub heaths and grass grass. Your focus resources it has in companies of Class Nardo Callunetea. In addition, it also occurs in those of the association Epilobion angustifolii or the sub-association Luzulo-Fagenion.

In the Allgäu Alps, it rises on the Steinmandl in Vorarlberg up to 1980 m above sea level.
