The bird's foot sedge ( Carex ornithopoda ) is a species of sedge ( Carex ) native to Central Europe . It is a variegated sedge.

description

The bird's foot sedge is a perennial plant , grows in small clumps and has a central, sterile rosette of leaves. It becomes 8 to 15 cm high. The stems are lateral and upright, almost stalk-round and rough in the upper area. The leaves are usually less than 10 cm long and 1 to 3 mm wide. They are coarse, pale green and slightly shiny. The leaf margin is rough. The abdominal vaginal wall is red and deeply indented. The leaves are shorter than the stem. The basal leaf sheaths are light brown to dirty purple and frayed.

There are two to four female spikelets , each with two to five loose flowers . The spikelets are 6 to 10 mm long, the lower ones are clearly stalked and protrude with their stalk from their bract. The spikelets are fingered closer together. The male spikelets are up to 8 mm long and narrow. The bracts are red to pale brown and almost always have a narrow skin edge. They are obovate and not serrated. The stylus has two scars . The fruit is 2.5 to 3 mm long and longer than its bract. It is hairy and has a thin beak.

Flowering time is April to June.

The number of chromosomes is 2n = 52 or 54.

distribution

The species is native to sub-ocean Europe up to Turkey and is a submeridional-alpine to temperate-montane and boreal flora element. It is widespread in the Alps, but scattered to rare in the rest of Germany. It grows in warmth-loving forests, bushes and semi-arid grasslands. She is chalky. In Central Europe it focuses on the Erico-Pinion societies, but also occurs in the Carici-Fagetum, in the Alno-Ulmion societies, Quercion pubescentis, Berberidion or in open Brometalia and Seslerietalia societies.

Systematics

There are two subspecies, which some authors also regard as species:

  • Carex ornithopoda subsp. ornithopoda : It occurs in Europe and Turkey. In the Allgäu Alps in Vorarlberg on the Üntscheller near Schoppernau , it rises to 2130 m above sea level.
  • Carex ornithopoda subsp. ornithopodioides (Hausm.) Nyman (Syn .: Carex ornithopoda subsp. elongata (Leyb.) Vierh. , Carex ornithopodioides Hausm. ): It occurs in Central and Southern Europe in snow- soil societies as Arabidetalia caeruleae-order character, but also in Caricetum firmae in the high mountains. They are found in the Allgäu Alps between 1500 m and 2200 m above sea level. It has the chromosome number 2n = 54.
