Carex appropinquata
Black - crested sedge ( Carex appropinquata ) in the Botanical Garden Munich- Nymphenburg
The black-haired Sedge ( Carex appropinquata ) is a plant from the family of the family of the Sedge family ( Cyperaceae ). A commonly used synonym is Carex paradoxa Willd., From which we derive also the German name Weird sedge and sedge miracle. The species forms clumps with a black-brown fiber tuft of dissolved leaf sheaths at the base. The stalks can reach heights of 30 to 80 centimeters and the inflorescences are racemose panicles - ährig. The distribution area is located in Central and Northern Europe and extends to Siberia. The black-haired Sedge applicable in Austria and Germany as endangered. It provides scattering, but can be poorly mowed.

Description
Appearance and leaves
The black-haired Sedge is a perennial, herbaceous plant that forms dense, bultige clumps. There is a black-brown, shiny fiber tuft of dissolved leaf sheaths at the base. The stalks stand upright and can reach a height of 30 to 80 centimeters. They are thin and triangular and rough in the upper part. Leaf blades are flat, 2-3 mm wide, usually green, sometimes gray-green, little stiff and rough cutting. Never outshine the inflorescence. There shall be no foothills.
Inflorescence, flowers and fruit
The inflorescences are strongly contracted, little branched, ährig - racemose, rarely also loose and sagging panicles. They are 2-8 rarely to 10 inches long with diameters of 0.5 to 1.5 centimeters. The inflorescence branches are mostly from upright and have spelzige, sometimes deciduous leaf-like bracts. The lowest branch usually reaches a length of 1.5 to 2.5 centimeters. The spikelets are oval to cylindrical, 4-15 mm long. The female flowers are in the lower part, the male in the upper part of the spikelets. The glumes are reddish brown, broadly oval, pointed, and 3 millimeters long. The fruit hoses are dark brown, matte, clear along annoying, also 3 millimeters long, roundish ovate, and suddenly go into a beak on. It also forms two scars. It blooms in May and June.

Distribution and ecology
The natural range of the black-haired Sedge is located in Central and Northern Europe and extends to Siberia. The species grows in Central Europe scattered from the lowlands up to about 1500 meters altitude in the Alpine region. They are found on wet meadows, swamps, ditches and forest ponds usually on lime-free, nutrient-poor peat soils. It is a companion plant of the sedge meadows ( Magnocaricion ) and the alder swamps ( Alnion ). The black-haired Sedge promotes siltation. The fruits contain a swimming tissue and are transported through the water.
The species is critically endangered in Austria and in Germany.
Systematics and history of research
The black-haired Sedge ( Carex appropinquata ) is a species in the genus of sedges ( Carex ) in the family of the Sedge family ( Cyperaceae ). It is assigned to the subgenus Vignea. The species was described in 1801 by Heinrich Christian Friedrich Schumacher in his work Enumeratio Plantarum in Partibus Saellandiae Septentrionalis et Orientalis first time scientifically. The genus name comes from the Latin and Carex designated grasses with cutting blades. The specific epithet appropinquata also comes from Latin and means " pushed ". It refers to the strongly contracted panicle.
The construction of the inflorescence is approximately between the panicles of sedge ( Carex paniculata ) and the wire sedge ( Carex diandra ), but you can distinguish the type of the fiber tuft good of the other two. The also similar comb - sedge ( Carex disticha ) differs by its foothills of the Black Crested Sedge.

Use
The black-haired Sedge provides good litter, can only mow bad but because of the tight horstigen growth.
