Bachelot de la Pylaie's cottongrass

The Bachelot de la Pylaie's cottongrass (Eriophorum pylaieanum) is a species in the genus Eriophorum. Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Common Cotton-Grass

<em>Eriophorum angustifolium</em>, commonly known as common cotton grass or many-stalked cottongrass, is a perennial sedge in the family Cyperaceae. It is distributed across peatlands, bogs, fens, and wet moorlands of Europe and North America, where it is often a dominant and ecologically significant species. Common cotton grass is easily recognized by its distinctive fluffy white seed heads, which resemble balls of cotton and appear conspicuously across boggy landscapes in late spring and summer. These cotton-like structures are modified perianth bristles that aid in wind dispersal of seeds. The species plays a vital role in peatland ecosystems as a peat-forming plant and provides food and nesting material for various wetland birds. It is assessed as Vulnerable on the IUCN Red List, reflecting ongoing habitat loss due to peatland drainage, agricultural conversion, and climate change. Biological traits of this species remain poorly documented in the scientific literature.
