description

Left: male flower with bract; right: female flower (bract and tube)

The sedge sedge is a perennial herbaceous plant , stature heights of 5 to 30, rarely reached up to 60 centimeters. It develops numerous, up to 2 mm thick, smooth, triangular, unleaved stems. The light green leaves are 1.5–2.5 mm wide. Below the inflorescence there are 2–5 bracts that protrude far beyond the inflorescence. The lowest bract is 3–15 cm long and continues the direction of the stem. The inflorescence is a green, later light brown head made up of numerous spikelets. The spikelets themselves are many-flowered, dense and have the male flowers at the base. The husks are only half as long as the tubes, white-skinned on the edge and with a green central nerve. The tubes are 7–10 mm long, green, later light yellow, glabrous and narrowed at the top into a two-toothed beak. The female flowers have 2 stigmas; the fruit is shiny, light brown. The species blooms between June and September. Their chromosome number is 2n = 80.

Occurrence

The sedge sedge thrives on wet, nutrient-rich, sandy clay or mud soils on dry lake or pond banks and on rivers. It can suddenly appear in abundance and soon disappear again as the plants only last a few years. The species is a characteristic of Carici-Eleocharitetum ovatae (Nanocyperion). It only rises up to 1000 m in the mountains. Its distribution area is Europe and Asia (Caucasus to Japan). In Europe it avoids the north and is extremely rare in the south. It is also rare in Central Europe.
