It is a genus of monocotyledonous flowering plants, commonly known as rushes.
Plant with few to many stems. Stems (5-)10-20(-30) cm, erect and usually stout, with 1-4 usually long leaves below the inflorescence, the lower bracts long, leaf-like. Leaves 2-7(-10) cm, usually 0.5-1 mm wide, flat, with convolute margins. Flowers usually in 1-10 capitate clusters. Perianth-segments 3.5-8.5 mm, usually mostly scarious; outer narrowly ovate to lanceolate; inner narrowly ovate to lanceolate, obtuse or subacute. Stamens 6, 1/3-1/2 as long as the perianth; anthers 0.4-0.8 mm, 2/3-4/5 as long as the filaments. Capsule 3.5-4.5 mm, equalling or slightly shorter than the inner perianth-segments, obtusely angled to ellipsoid, subacute to obtuse, often with a raised style-base; style usually deciduous. Seeds 0.3-0.4 mm, broadly ellipsoid to ovoid, usually obtuse, smooth. Flowers occasionally cleistogamous.
This plant is useful.
How to get rid of:
Dig up the area thoroughly. This is not an easy job, because it is not enough just to dig up the ground - you also need to scrupulously select all the rhizomes from it.
