There are one to three female spikelets . They are dense, sessile and erect. There is a male spikelet. The lowest bract is dry-skinned and broadened at the base. It has almost no sheath and does not usually protrude beyond its spikelet. The bracts are blunt, broadly obovate, dark red-brown and with a white dry skin margin. A median strip is missing, at the front end the bract is often fringed ciliate. The stylus has three scars . Flowering time is March and April.

The fruit is 2 to 2.5 mm long, hairy. It is obovate to spherical. The beak is short, two-toothed and trimmed.

distribution

The heather sedge is native from Europe to Mongolia and is a plant that occurs in submeridional-montane to boreal, continental climates. In Germany it is scattered, rare in the southwest and widespread in the northeast. In the Allgäu Alps, it rises in the Tyrolean part between Oberellenbogen and the Elbognerspitze up to 1540 m above sea level.

It grows in subcontinental heaths and dry pine forests. In Central Europe it is a character species of the Pyrolo-Pinetum from the Cytiso-Pinion association, but also occurs in societies of the Erico-Pinion association, in the eastern areas also in the Genistion association and in the Elynetum in the central Alps.
