Willd. |
The plant genus Schuppenseggen ( Kobresia ), also known as Schuppenried , belongs to the sour grass family (Cyperaceae). The approximately 57 species are common in the northern hemisphere .
description
The common sedge species are perennial herbaceous plants that usually form lawns. Their stem is round or indistinctly triangular, it is usually only leafed at the base. The leaves are folded like bristles or narrow and runny.
The inflorescence is terminal, spiked or narrow panicle. The lower part usually consists of hermaphrodite spikelets that sit along an axis or in a contracted panicle. The inflorescence goes above into single-flowered, all-female spikelets, then into male spikelets. In species with a compound inflorescence, this order also applies to the side branches. For the sake of simplicity, all flowers behind a glume are referred to as spikelets, even if - as with the genus Sedge ( Carex ), which is closely related - the purely male flowers are viewed as flowers and not as reduced inflorescence. The flowers are threefold. There are no bracts. There are three stamens. The stylus is usually three columns and its base permanent.
The nut fruits are mostly triangular and surrounded by a perigynium (utriculus). But this is open here on one side.
Systematics and distribution
The genus Kobresia was established by Carl Ludwig Willdenow in Species Plantarum . The scientific generic name Kobresia honors Joseph Paul von Cobres (Kobres) in Augsburg , who owned a large collection of natural objects that the Bavarian state later bought up. The later genus Elyna Schrad. , in which the nude song was placed, is now mostly incorporated in Kobresia . Synonyms for Kobresia Willd. are: Elyna Schrad. , Hemicarex Benth. , Blysmocarex N.A.Ivanova .
The genus Kobresia belongs to the tribe Cariceae in the subfamily Cyperoideae within the family Cyperaceae .
The approximately 57 species thrive mainly in temperate areas of the northern hemisphere in the high mountains of Eurasia , in North America and in the Arctic . There are around 44 species in China, 16 of them only there. In Europe there are only two species, the naked sedge ( Kobresia myosuroides ) and the two-part common sedge ( Kobresia simpliciuscula ). The Siberian common sedge ( Kobresia sibirica ) has not yet been proven with certainty in Europe.
The genus includes about 57 species. However, some authors place them under the Carex genus :
- Kobresia burangensis Y.C.Yang : This species is only known from the type material of a young specimen that is not yet capable of flowering. It wascollectedin 1987 on a grass slope at an altitude of about 5000 meters in Burang in the southwestern part of the Xizang autonomous region.
