Carex disticha is a Eurasian species of sedge known as the brown sedge [1] or, in North America, tworank sedge. [2]
Carex disticha is native to parts of Northern and Western Europe, where it grows in moist spots in a number of habitat types, and it has been introduced to the Great Lakes region of southern Canada. [3] In its native range, this species is often associated with the Juncus subnodulosus–Cirsium palustre fen-meadow habitat. [4] Carex disticha has also been introduced to Canada, where it is known from only two sites, in Ontario and Quebec. [3] [5]
Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hairs.
Cirsium palustre, the marsh thistle or European swamp thistle, is a herbaceous biennial flowering plant in the daisy family, Asteraceae.
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 plant species belonging to the division of horsetails (Equisetopsida). It is widespread in cooler regions of North America and Eurasia.
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 diandra is a species of sedge known by the common names lesser tussock-sedge and lesser panicled sedge.
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 praegracilis is a species of North American sedge known as clustered field sedge, field sedge, and expressway sedge. Carex praegracilis is cultivated in the specialty horticulture trade as lawn substitute and meadow-like plantings.
Carex scoparia is a species of sedge known by the common names broom sedge and pointed broom sedge. It should not be confused with the unrelated grass species known as "broom sedge," Andropogon virginicus.
Carex vulpinoidea is a species of sedge known as fox sedge and American fox-sedge. It is native to North America, including most of Canada, the Dominican Republic, the United States and parts of Mexico. It is known in Europe and New Zealand as an introduced species. The sedge lives in wet and seasonally wet habitat, and grows easily as a roadside weed. It produces clumps of stems up to a meter tall. The inflorescence is a dense, tangled cluster of many flower spikes up to about 10 cm (3.9 in) long. Tolerates fluctuating water levels and periods of drying.
Trodds Copse is a 25.23 hectare biological Site of Special Scientific Interest (SSSI), in central Hampshire, notified in 1989. It comprises ancient semi-natural woodland, unimproved meadows and flushes.
Carex acutiformis, the lesser pond-sedge, is a species of sedge.
Carex lutea is a rare species of sedge known by the common names golden sedge and sulphur sedge. It is endemic to North Carolina, where it is known only from Pender and Onslow Counties in the Cape Fear River watershed. There are nine populations. The plant was discovered in 1991 and described to science as a new species in 1994, and it has not been thoroughly studied nor completely surveyed yet. Its rarity was obvious by 2002, however, when it was federally listed as an endangered species.
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 saxatilis is a species of sedge known by the common names rock sedge and russet sedge.
Carex distans, commonly known as distant sedge, is a plant species in the sedge family, Cyperaceae. It is native to Europe and North Africa. It is part of a complex of similar species that occur across Eurasia. Its relatives include Carex diluta of central Asia, which has also introduced to North America in Montana. Carex distans has been introduced to the US states including Maryland and Pennsylvania. More recently, it was found in Oregon. There is a report from Victoria, Australia as well.
Carex lacustris, known as lake sedge, is a tufted grass-like perennial of the sedge family (Cyperaceae), native to southern Canada and the northern United States. C. lacustris us an herbaceous surface-piercing plant that grows in water up to 50 cm (1.6 ft) deep, and grows 50–150 cm (1.6–4.9 ft) tall. It grows well in marshes and swampy woods of the boreal forest, along river and lake shores, in ditches, marshes, swamps, and other wetland habitat. It grows on muck, sedge peat, wet sand or silt, in filtered or full sunlight.
Chyenhal Moor is a poorly drained shallow valley, 2 miles (3.2 km) to the south-west of Penzance, Cornwall. Due to several rare plants in a diverse range of habitats, it was notified as a Site of Special Scientific Interest (SSSI) in 1951.
