The short-term sedge ( Carex brachystachys ) is a species of sedge ( Carex ) native to Central Europe . It is a variegated sedge.
description
The short-term sedge is a perennial plant , grows densely and does not form runners. It becomes 15 to 40 cm high. The stems are thin, round, limp and smooth. They are only leafy at the base and usually slightly longer than the leaves. The leaves are finely rolled into bristles and up to 1 mm wide. The basal leaf sheaths are brown to reddish brown and disintegrate into plates.
The only male spikelet is light rust-brown and has a long stalk. Sometimes there are female flowers at its tip. The two or three female spikelets are loose-flowered and 1.5 to 2 cm long. They are 7 to 10 times as long as they are wide. They stand apart, their stems are long and thin. They hang when the fruit is ripe. The lower bract is usually shorter than the spikelet.
The bracts are purple-brown, have a narrow skin edge and a green central vein. They are entire, not long pointed. Sometimes they are slightly serrated at the top. They are shorter than the fruit. The stylus has three scars . Flowering time is June to August.
The fruit is 3 to 4 mm long, glabrous and fine-veined. The shape is lanceolate, slender, 3 to 4 times as long as it is thick. It gradually narrows into the beak.
The number of chromosomes is 2n = 40.
distribution
The species occurs in the mountains of Central and Southern Europe and is a submeridional-subalpine to temperate-subalpine, oceanic flora element. It is widespread in the Alps and is also found in the Black Forest. It grows in damp limestone crevices, on trickled rocks, in ravines and on tufa. It is a character species of the Caricetum brachystachyos from the association Cystopteridion. It rises to 2200 m above sea level.
