Vegetative characteristics

The hare's paw sedge is a deciduous, perennial herbaceous plant that reaches heights of between 10 and 60 centimeters. It does not form runners , but small to medium-sized solid clumps that do not disintegrate. Their stems have tangible knots at the bottom, which are usually 2 to 3 millimeters thick and appear rounded, triangular. In addition to flowering shoots, there are also vegetative shoots with several layers of leaves arranged one above the other.

The leaves are always shorter than the stem, 2 to 4 millimeters wide, rigid, light green to yellow-green in color and folded twice on the inside in the upper half; they usually run into a clear, usually long, triangular point. The leaf sheaths have distinct dark green nerve lines, but are mostly pale, rarely brown in color.

Generative characteristics

The hare's paw sedge is a sedge of the same age. The inflorescence , which is up to 4 centimeters long, contains four to seven spikelets when standing together . The yellow-brown to brown spikelets are egg-shaped with a length of 6 to 10 millimeters and a width of 5 to 7 millimeters. The female flowers are at the tip of the spikelet and the male flowers at the base. The elongated, pointed husks are as long as the 3 to 5 millimeters long and 2 millimeters wide winged tubes, which are not spread when ripe. They enclose two scars.

The species chromosome number is 2n = 64, 66 or 68.

ecology

The hare's paw sedge is a hemicryptophyte . There is also vegetative reproduction with the help of their rhizome .

The flowering time is in June and July. The pollination is carried by the wind ( anemophily ), but it is believed that in this Seggenart insects could act as pollinators ( Entomophilie ). For example, their long-lived seeds self-propagate ( autochory ).

Occurrence

The hare's foot sedge is common in the temperate zones of Eurasia. It is also found in the Azores, northwest Africa, and from western Canada to the western United States. In the other areas of North America as well as in Tasmania and New Zealand it is a neophyte .

This article or paragraph presents the situation in Germany . Help us to describe the situation in other countries.

The hare's paw sedge is relatively widespread throughout Germany , it is only rare in arid regions and on lime-rich soils . In the Allgäu Alps in Bavaria, it rises at the summit of the Schnippenkopf up to 1820 m above sea level.

The lime-avoiding hare paw sedge occurs on moist to sometimes waterlogged and often acidic meadows , pastures and grasslands . It is part of Kleinseggenrieden. It is also found on the edges of ditches or in forest fields. It thrives on dammed-seepage damp or alternately damp, moderately nutrient-rich, base-poor, peaty soils.
