description

Vegetative characteristics

The Banat sedge is a perennial herbaceous plant and reaches heights of 45 to 90, rarely up to 120 centimeters. It forms elongated runners . The stems are sharp triangular and very rough on top. The leaves are up to 10 mm wide on non-flowering shoots and curl down as they dry. The basal sheaths are spideless, red-brown to black-brown and frayed with a strong network.

Generative characteristics

The flowering time is in April and May. The Banat sedge is a variegated sedge. The male and female spikelets are different, but all slender cylindrical. The lower spikelets in particular are distant. There are one to three male and three to five female spikelets. The female spikelets are up to 10 centimeters long, have a short stalk, stand upright and later hang over. The lowest bract is leaf-like and longer than its spikelet, but shorter than the entire inflorescence .

The bracts of the female flowers are blackish and have a green central stripe. They are elongated and blunt, shorter than the fruit. The stylus has two scars .

The green, bare fruit is 2 mm long, veinless, flat on the inside, arched on the outside and has a very short beak.

Occurrence

The Banat sedge occurs from Central Europe to the Caucasus. The main distribution area of ​​the Banat sedge is in south- eastern Europe and in the eastern Mediterranean , and it extends from there eastward to Kazakhstan . It is a submeridional to subtemperate, subcontinental flora element .

In Central Europe it occurs only sporadically in Saxony-Anhalt , in Saxony (for example in the Elbe valley near Dresden ) on river banks; it is rare in the Bavarian Forest in Lower and Upper Austria.

It grows in a very warm summer climate on river banks and riparian forests. The Banat sedge thrives best on loose, base-rich, often slightly boggy, loose-sand or fine-gravel soils with groundwater flowing through them . It is a character species of the Caricetum buekii from the Magnocaricion association.
