About Carex acutiformis Ehrh.
Carex acutiformis Ehrh. is a tuft-forming, rhizomatous plant that grows up to 150 centimetres (59 in) tall. Its stems are slender and three-angled. The leaves are narrow, tend to droop at the tips, and reach up to 160 cm (63 in) long and 5–20 mm (0.2–0.8 in) wide. Its inflorescence holds 2 to 3 male spikelets and 3 to 4 female spikelets. Male spikelets are 1 to 4 cm long and typically purple-brown. Female spikelets are 2 to 5 cm long, cylindrical, erect, and short-stalked. This species is native to parts of northern and western Europe, where it grows in moist locations across multiple habitat types. Within its native European range, it is often associated with the Juncus subnodulosus–Cirsium palustre fen-meadow habitat, and it is a dominant plant in the Carex acutiformis swamp plant association.
