Carex acutiformis | |
Carex acutiformis, the lesser pond-sedge, [1] is a species of sedge.
It grows up to 150 centimetres (59 in) tall, with leaves up to 160 cm (63 in) long and 5–20 mm (0.2–0.8 in) wide. [2]
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 subnodulosus–Cirsium palustre fen-meadow habitat. [3] It is also a dominant plant in the Carex acutiformis swamp plant association. [4]
Cirsium palustre, the marsh thistle or European swamp thistle, is a herbaceous biennial flowering plant in the family Asteraceae.
A reedbed or reed bed is a natural habitat found in floodplains, waterlogged depressions and estuaries. Reedbeds are part of a succession from young reeds colonising open water or wet ground through a gradation of increasingly dry ground. As reedbeds age, they build up a considerable litter layer that eventually rises above the water level and that ultimately provides opportunities in the form of new areas for larger terrestrial plants such as shrubs and trees to colonise.
Lotus pedunculatus, the big trefoil, greater bird's-foot-trefoil or marsh bird's-foot trefoil, is a member of the pea family (Fabaceae).

Yanal Bog is a 1.6 hectare biological Site of Special Scientific Interest on the southern edge of the North Somerset Levels, just north of the village of Sandford, North Somerset. It was notified as an SSSI in 1988.
Equisetum palustre, the marsh horsetail, is a perennial herbaceous pteridophyte belonging to the subclass of horsetails (Equisetidae). It is widespread in cooler regions of Eurasia and North America.
Carex pauciflora, the few-flowered sedge, is a perennial species of sedge in the family Cyperaceae native to bogs and fens in cool temperate, subarctic, and mountainous regions of the Northern Hemisphere. The specific epithet pauciflora refers to the Latin term for 'few flowered'.
Carex pendula is a large sedge of the genus Carex. It occurs in woodland, scrubland, hedges and beside streams, preferring damp, heavy clay soils. It is sometimes grown as a garden plant because of its distinctive appearance.
Carex buxbaumii is a species of sedge known as Buxbaum's sedge or club sedge. It is native to much of the northern Northern Hemisphere, from Alaska to Greenland to Eurasia, and including most of Canada and the United States. It grows in wet habitat, such as marshes and fens. This sedge grows in clumps from long rhizomes. The stems are 75–100 cm (30–39 in) in maximum height. The leaves are narrow and small. The inflorescence has a bract which is sometimes longer than the spikes. The fruits have dark-colored bracts and a sac called a perigynium or utricle which is gray-green and rough in texture.
Carex leporina is a species of sedge known in the British Isles as oval sedge and in North America as eggbract sedge. It is native to Eurasia and eastern and western North America, where it grows in seasonally wet habitat, such as meadows and fields. This sedge produces many thin stems and narrow leaves. The inflorescence is an open cluster of several flower spikes. The pistillate flower has a reddish or brownish bract with a gold center and white tip.
Carex disticha is a Eurasian species of sedge known as the brown sedge or, in North America, tworank sedge.
Carex riparia, the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest Carex, growing up to 130 cm tall, with glaucous leaves up to 160 cm long. It hybridises with a number of other Carex species, including the closely related Carex acutiformis – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass.
Carex hirta, the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus Carex.
Carex binervis, the green-ribbed sedge, is a European species of sedge with an Atlantic distribution. It is found from Fennoscandia to the Iberian Peninsula, and occurs in heaths, moorland and other damp, acidic environments. It typically grows to a height of 15–120 cm (6–50 in), and has inflorescences comprising one male and several female spikes, each up to 45 mm (1.8 in) long. The utricles have two conspicuous green veins, which give rise to both the scientific name and the common name of the species. In the vegetative state, it closely resembles C. bigelowii, a species that usually grows at higher altitude. C. binervis was first described by James Edward Smith in 1800, and is classified in Carex sect. Spirostachyae; several hybrids with other Carex species are known.
Carex pilulifera, the pill sedge, is a European species of sedge found in acid heaths, woods and grassland from Macaronesia to Scandinavia. It grows up to 30 cm (12 in) tall, with 2–4 female spikes and 1 male spike in an inflorescence. These stalks bend as the seeds ripen, and the seeds are collected and dispersed by ants of the species Myrmica ruginodis.
Carex bigelowii is a species of sedge known by the common names Bigelow's sedge, Gwanmo sedge, and stiff sedge. It has an Arctic–alpine distribution in Eurasia and North America, and grows up to 50 centimetres (20 in) tall in a variety of habitats.
Carex pseudocyperus is a species of flowering plant in the sedge family known by the common name cyperus sedge or hop sedge. It grows in marshes, swamps, and the margins of ponds, rivers and canals. The stems can be up to 90 centimetres (35 in) with one male spike and 3 to 5 pendulous female spikes, and bright yellow-green leaves to 1.2 metres.
Carex pulicaris, the flea sedge, is a species of sedge in the genus Carex native to Europe.
Carex elongata, the elongated sedge, is a species of flowering plant in the family Cyperaceae, native to Europe, the Caucasus, western Siberia, Kazakhstan, and the Altai. It occurs in boggy woodland and wet meadows, where it forms dense tussocks up to about 1 m tall.
