Eriophorumlajit

Eriophorum is a genus of flowering plants in the sedge family, Cyperaceae, commonly known as cotton-grasses. These plants are found in temperate and cold regions of the Northern Hemisphere, typically in wet habitats such as bogs, marshes, and fens. The genus name Eriophorum is derived from Greek words meaning "wool-bearing," referring to the plant's distinctive fluffy seed heads.

Cotton-grasses are perennial herbs that grow from rhizomes. They are characterized by their grass-like leaves, which are often narrow and triangular in cross-section. The flowers are borne in spikelets, which are clustered together. After flowering, the spikelets develop into a mass of silky white or brownish hairs, which surround the seeds. These hairs aid in wind dispersal.

Several species of Eriophorum are recognized, with variations in height, leaf structure, and the appearance of the cottony inflorescences. Eriophorum vaginatum, commonly known as hare's-tail cotton-grass, is widespread and often forms dense tussocks. Other species include Eriophorum angustifolium (common cotton-grass) and Eriophorum latifolium (broad-leaved cotton-grass). These plants play a role in their ecosystems by providing habitat and food for various invertebrates and birds, and their root systems help stabilize wetland soils.
