The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large; botanists have described some 5,500 known species in about 90 genera – the largest being the "true sedges", with over 2,000 species.
Carex is a vast genus of over 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.
Carex stricta is a species of sedge known by the common names upright sedge and tussock sedge. The plant grows in moist marshes, forests and alongside bodies of water. It grows up to 2 feet (0.61 m) tall and 2 feet (0.61 m) wide. When the leaves die, they build on top of or around the living plant, making a "tussock". Widely distributed in and east of the Great Plains, it is one of the most common wetland sedges in eastern North America.
Carex sparganioides, known as bur-reed sedge or loose-headed bracted sedge, is a perennial plant belonging to the sedge family (Cyperaceae). Its native range includes most of the eastern and central United States and eastern Canada. In Maine, it is typically found in hardwood or mixed forests.
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 pensylvanica is a species of flowering plant in the sedge family commonly called Pennsylvania sedge. Other common names include early sedge, common oak sedge, and yellow sedge.
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 oronensis is a species of sedge known by the common name Orono sedge. It is endemic to Maine in the United States, where it occurs mainly in the Penobscot River Valley. It is the only plant that is endemic to the state of Maine. The type locality is Orono.
Carex prairea, common name prairie sedge, is a species of Carex native to North America. It is a perennial.
Carex typhina, often called the cattail sedge, is a rare species of Carex known to grow in wetlands. It is native to North America.
Carex careyana, commonly known as Carey's sedge, is a species of sedge found in the eastern United States and Ontario, Canada.
Carex muehlenbergii is a species of flowering plant, it is a type of sedge. It is a grass-like plant in the family Cyperaceae. Its common names include sand sedge, Muhlenberg's sedge.
Carex bullata is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to south eastern parts of Canada and eastern parts of the United States. It has the common name of the button sedge.
Carex vestita, also commonly known as velvet sedge, is a tussock-forming species of perennial sedge in the family Cyperaceae. It is native to eastern parts of the United States.
