Botanical Description
A yellowish-gray-green plant with a short creeping rhizome , giving short underground shoots and forming turfs.
The stems are thin, but strong, smooth, (5 [3] ) 10-30 (40) cm tall. Shoots are surrounded at the base by brown leaf sheaths.
Leaf blades 3-4 mm wide, very stiff, almost leathery, curved, flat, half-folded or with an edge wrapped back, long pointed, half or 3-4 times [3] shorter than the stem.
The upper spikelet is staminate , club-shaped or oblong-elliptic, dense, (0.5) 1-2 cm long [3] , with obovate, widely light-membranous-bordered, ciliate, brown or wide brown stripe in the middle and blunt scales along the edge ; the rest are pistillate , including 1-2, slightly spaced, slightly flowered and short, dense, ovate, spherical or oblong-ovate, (0.4) 1-1.5 cm long [3] , almost sessile, with widely obovate or ovoid , at the top, roundly blunt or islet, rusty-brown, with a light, chestnut-brown or dark-brown stripe in the middle, wide and uneven or upwards white-membranous, usually with or without fringed scales, almost equal to sacs or slightly shorter . Pouches are almost rounded in cross section or rounded trihedral, obovate or broadly obovate, 2–2.5 [3] (3) mm long, thin-leathery, yellowish or brownish-green, possibly rusty upward, later brownish, dense or diffuse pubescent over the entire surface, without veins , with barely notched, very short, 0.2 mm long, wedge-shaped nose. The lower covering sheet is scaly, with a bristle tip, shorter than the inflorescence .

Distribution and Ecology
Northern, Atlantic and Central Europe ; The Arctic part of Russia : northeast of the Kola Peninsula ; The Baltic states ; The European part of Russia : all areas except Nizhne-Volzhsky; Belarus ; Ukraine : all areas; Caucasus : the vicinity of Stavropol ; Western Siberia : all areas except the Arctic and Altai ; Central Asia : Northern Mongolia .
It grows in light dry pine , less often larch forests , along the edges, in glades and clearings, in hedgehogs, on dry gravel and rocky slopes, sometimes on dry meadows and in gravelly lichen tundra ; on the plain and in the forest belt of the mountains, less often in the highlands, mostly on sandy soil.
Spikelets regularly visit honey bees during flowering to collect pollen , probably also pollinating them, as this species is one of the earliest flowering ones [4] .
