linaigrette à anthères courtes

Closed-sheathed cottongrass is a sedge in the genus Eriophorum (family Cyperaceae) characterized by leaf sheaths that are fused to form a closed tube around the stem, a morphological feature distinguishing it from open-sheathed relatives. Cottongrasses are quintessential plants of northern peatlands, bogs, and acidic fens across the boreal and arctic zones of the Northern Hemisphere, producing conspicuous cottony white seed heads — modified perianth bristles elongating as fruits mature — that transform peat bogs into spectacular white-tufted landscapes in late spring and early summer. These plants are ecological keystones of Sphagnum-dominated peat bogs, contributing organic matter through their dense root systems that resist decomposition in waterlogged, oxygen-depleted conditions, driving peat formation over millennia. Eriophorum species serve as important food plants for ptarmigan, geese, and various invertebrates in arctic and subarctic ecosystems. Climate change threatens cottongrass habitats through warmer temperatures accelerating peat decomposition, altered hydrological regimes, and permafrost thaw that fundamentally transforms the structure of northern peatlands.

<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.
