Description

Carex acutiformis is a tuft-forming, rhizomatous plant growing up to 150 centimetres (59 in) tall. Stems are slender and three angled. Leaves are narrow, with a tendency to droop at the tips, and measuring up to 160 cm (63 in) long and 5–20 mm (0.2–0.8 in) wide. Inflorescence consists of 2 to 3 male and 3 to 4 female spikelets. Male spikelets measure 1 to 4 cm, and are generally purple-brown in colour. Female spikelets measure between 2 and 5 cm, and are cylindrical in shape, erect and short-stalked. [2] [3]

Ecology

It is native to parts of northern and western Europe, where it grows in moist spots in a number of habitat types. In its native European range this species is often associated with the Juncus subnodulosusCirsium palustre fen-meadow habitat. [4] It is also a dominant plant in the Carex acutiformis swamp plant association. [5]
