The eriophorum scheuchzeri ( Eriophorum scheuchzeri ), also Alpine Wollgras called, is a plant from the genus Wollgräser ( Eriophorum ) within the family of Cyperaceae (Cyperaceae). With its long foothills that penetrate far into the water, it contributes significantly to the silting up of alpine waters. The specific epithet Scheuchzeri honors the natural scientist Johann Jakob Scheuchzer .
description
Scheuchzer's cottongrass grows as a perennial herbaceous plant and reaches heights of 10 to 40 centimeters. It forms very long red-brown runners . The simple leaf blades are short with a smooth edge.
The flowering period extends from June to September.
The chromosome number of the species is 2n = 58.
ecology
Scheuchzer's cottongrass is a hemicryptophyte .
Occurrence
The distribution area of Scheuchzer's cottongrass stretches from Europe to the western Himalayas and Mongolia and includes subarctic and subalpine North America. Scheuchzer's cottongrass is rarely found, mostly in smaller and occasionally in larger stands, especially in the central chains of the Alps with crystalline rock. In larger areas of Central Europe it is completely absent.
Scheuchzer's cottongrass occurs at altitudes of 1500 to 2000 meters in the subalpine to alpine altitudes . In the Allgäu Alps in the Tyrolean part near the Hermann-von-Barth-Hütte it rises up to 2100 m above sea level.
It grows on wet, more or less nutrient-poor peat . Scheuchzer's cottongrass thrives in flat moors, muddy ponds, ditches and lakes and silting areas of stagnant water. It thrives best on not too base-like, peaty or raw humus- containing , wet soils . Where it forms larger stands on high alpine lakes with flat banks, it contributes significantly to their silting up . It is a character species of the Eriophoretum Scheuchzeri from the association Caricion fuscae.
