In the Red List of Belarus it is included for the first time. The protected plant of Lithuania, Latvia and Poland.
Perennial grassy plant with a short creeping rhizome and upright stalks 50-100 cm high. Sheet plates flat, up to 8 mm wide. Inflorescences - sprawling whisks up to 20 cm long. Cones are 2-3-floral, 5-10 mm long, greenish or brownish-golden. Lower floral scales with two short edges and the awn leaving their top third. Awns are curved, in the lower part a little twirled, at the end of blossoming unbent down. A fruit - a zernovka, up to 4 mm long, above with quite large appendage.
Eurasia, North America (Alaska and Aleutian Islands). In Belarus is on the western border of an area. It is noted in Dokshitsky, Dubrovensky, Kamenetsky, Lepelsky, Logoysky and Minsk districts. There is gerbarny collecting from the Rogachevsky County, the Vyalovsky reserve (Volozhinyosky district) and the Mogilev province. According to literary data it is brought for Mogilev and Minsk.
Boggy woods (birch, pine and pine and birch) and meadows, key bogs.
Blossoms and fructifies in June-July. Anemofil. Breeds seeds and vegetativno. Anemokhor.
Number and tendency of its change:
The majority of populations small also occupy the small spaces (to 0,05 hectares). The largest population is revealed in the Dokshitsky district.
Major factors of threat:
Anthropogenous: drainage and plowing of lands, peatery, all views of cabins of the wood, economic transformation of lands, pasturage of cattle and excessive recreational loadings (trampling), early mowing (late mowing is inexpedient to carry out as after blossoming the plant strongly grows coarse).
Grows in territories of National park "Bialowieza Forest", the Berezinsky biospheric reserve, wildlife areas of "Servech" and "Plover" of the Dokshitsky district. Control of a condition of the known populations, search of new places of growth, the organization of the specialized botanical wildlife area in the Minsk district is necessary (vicinities of. The new Yard) with prohibition or restriction in places of growth of anthropogenous influences.
