Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions.
Carex is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges. Other members of the family Cyperaceae are also called sedges, however those of genus Carex may be called true sedges, and it is the most species-rich genus in the family. The study of Carex is known as caricology.
Bratton Downs is a 395.8 hectare biological and geological Site of Special Scientific Interest in Wiltshire, England, near the villages of Bratton and Edington, and about 3 miles (5 km) east of the town of Westbury. It was notified in 1971. The designated area consists mainly of chalk grassland, as well as some ancient woodland, and supports a diverse range of native flora and fauna. It overlays notable geological features—principally landforms created by glaciation in the Pleistocene.
Fimbristylis is a genus of sedges. A plant in this genus may be known commonly as a fimbry, fimbristyle, or fringe-rush. There are 200 to 300 species distributed worldwide. Several continents have native species but many species have been introduced to regions where they are not native. Some are considered weeds. These are typical sedges in appearance, with stiff, ridged stems and cone-shaped terminal panicles of spikelets. They are found in wet environments, and are most diverse in tropical and subtropical regions.
Kyllinga brevifolia is a species of sedge known by several common names, including shortleaf spikesedge, green kyllinga, perennial greenhead sedge, and kyllinga weed. It is native to tropical areas in the Americas but it can be found in warm regions around the world where it is an introduced species. This is a rhizomatous perennial herb growing one to several erect stems to heights up to about half a meter, often much shorter. It produces tiny inflorescences of a few spikelets each which in total are less than a centimeter long. Pollens are tiny, approximately 20-30 microns in size. It is sometimes a weed in wet areas such as cultivated land and irrigation ditches.
Tussock grasses or bunch grasses are a group of grass species in the family Poaceae. They usually grow as singular plants in clumps, tufts, hummocks, or bunches, rather than forming a sod or lawn, in meadows, grasslands, and prairies. As perennial plants, most species live more than one season. Tussock grasses are often found as forage in pastures and ornamental grasses in gardens.
Carex cusickii is a species of sedge known by the common name Cusick's sedge. It is native to Northwestern North America from British Columbia to California, and in Utah, where it can be found in several types of wet habitat, such as marshes, mountain meadows, and ditches. In its range it is most common in the Cascade Range and areas west.
Carex geyeri is a species of sedge known by the common names Geyer's sedge and elk sedge. It is native to western North America from British Columbia to California to Colorado, where it grows in dry areas in mountain meadows, grasslands, and open forest. This sedge produces scattered tufts of stems connected by a network of long rhizomes. The stems are triangular in cross-section and approach half a meter in maximum height. The inflorescence is composed of a cluster of staminate flowers and a cluster of pistillate flowers separated by a node.
Carex rossii, commonly known as Ross's sedge, is a hardy species of sedge that is often a pioneer species in areas with little or no established vegetation, or in places where disturbance has occurred. Ross's sedge grows in a variety of habitats throughout much of western North America, from Alaska to Ontario, south to New Mexico and California. It flowers in May and June.
Carex vesicaria is an essentially Holarctic species of sedge known as bladder sedge, inflated sedge, and blister sedge. It has been used to insulate footwear in Norway and among the Sami people, and for basketry in North America.
The Manitoba Tall Grass Prairie Preserve is located in southeastern Manitoba near Gardenton and Vita, this is about 50 kilometres (31 mi) south of Steinbach, Manitoba. It is one of the last remaining stands of tallgrass prairie in Manitoba and is part of the Tallgrass Aspen Parkland conservation area in Manitoba and Minnesota. Several groups and organizations help in land preservation in the Manitoba Tall Grass Prairie such as the Nature Conservancy of Canada, Nature Manitoba, Environment Canada, Manitoba Conservation and the Manitoba Habitat Heritage Corporation.
Uncinia uncinata, the Hawai'i birdcatching sedge, hook grass, hook sedge, bastard grass, kamu or matau-a-maui, is a species of flowering plant in the sedge family, Cyperaceae.
Carex bulbostylis, known as the false hair sedge, is a species of sedge native to the southcentral and southeastern United States. It was first formally named by Kenneth Mackenzie in 1915. It is also known as the eastern narrowleaf sedge, thick style sedge, and globose sedge.
Carex crawei, commonly called Crawe's sedge, is a species of flowering plant in the sedge family. It is native to North America, where it is widespread in the United States and Canada. Though widespread, it has a patchy distribution and is generally rare throughout its range. It is found in wet calcareous areas, usually associated with flat limestone outcrops or gravels. It is usually found in high quality natural habitats.
Carex fascicularis, commonly known as tassel sedge, is a species of sedge of the family Cyperaceae that is native to Western Australia and Victoria.
Carex inversa, commonly known as knob sedge, is a species of sedge of the family Cyperaceae that is native to Western Australia
Cyperus congestus, commonly known as dense flat-sedge or clustered flat-sedge, is a sedge of the family Cyperaceae that is native to southern Africa mostly in South Africa, Lesotho and Namibia.
Cyperus vaginatus, commonly known as stiff-leaf sedge or stiff flat-sedge, is a sedge of the family Cyperaceae that is native to Australia.
Cyperus zollingeri, commonly known as roadside flatsedge, is a sedge of the family Cyperaceae that is native to tropical areas of Australia, Africa and Asia.
Sitka Sedge State Natural Area is an estuary and beach on the north coast of the U.S. state of Oregon in Tillamook County. Sitka Sedge consists of 357 acres (144 ha) of tidal marsh, mudflats, dunes, forested wetlands, and uplands at the south end of the Sand Lake estuary, north of Tierra Del Mar.
