The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Eleocharis is a virtually cosmopolitan genus of 250 or more species of flowering plants in the sedge family, Cyperaceae. The name is derived from the Greek words ἕλειος (heleios), meaning "marsh dweller," and χάρις (charis), meaning "grace." Members of the genus are known commonly as spikerushes or spikesedges. The genus has a geographically cosmopolitan distribution, with centers of diversity in the Amazon Rainforest and adjacent eastern slopes of the South American Andes, northern Australia, eastern North America, California, Southern Africa, and subtropical Asia. The vast majority of Eleocharis species grow in aquatic or mesic habitats from sea level to higher than 5,000 meters in elevation.
Hypolytrum is a genus of plant in the family Cyperaceae. It contains approximately 60–70 species, native to tropical Africa, Asia, Australia, Latin America and various oceanic islands.
Uncinia is a genus of flowering plants in the family Cyperaceae, known as hook-sedges in Australia and as hook grasses or bastard grasses in New Zealand. The genus is characterised by the presence of a long hook formed by an extension of the rachilla, which is used to attach the fruit to passing animals (epizoochory), especially birds, and it is this feature which gives the genus its name, from the Latin uncinus, meaning a hook or barb.
Lepidosperma is a genus of flowering plant of the family Cyperaceae. Most of the species are endemic to Australia, with others native to southern China, southeast Asia, New Guinea, New Caledonia and New Zealand.
Gahnia is a genus of sedges native to China, Southeast Asia, New Guinea, Australia, New Zealand and a number of Pacific Islands. The common name is due to the toothed margins. It often forms tussocks.
Mesomelaena is a genus of sedges. It has 5 known species, all endemic to Western Australia.
Schoenoplectiella mucronata is a species of flowering plant in the sedge family known by the common names bog bulrush, rough-seed bulrush, and ricefield bulrush. It is native to Eurasia, Africa and Australia. It grows in moist and wet terrestrial habitat, and in shallow water. It is a perennial herb growing from a short, hard rhizome. The erect, three-angled stems grow in dense clumps and can reach a metre tall. The leaves take the form of sheaths wrapped around the base of stem, but they generally do not have blades. The inflorescence is a headlike cluster of cone-shaped spikelets accompanied by an angled, stiff bract which may look like a continuation of the stem.
Schoenoplectiella saximontana is a species of flowering plant in the sedge family known by the common name Rocky Mountain bulrush. It is native to North America, where it is known from several areas scattered throughout Canada, the United States, and Mexico. It grows in moist and wet habitat or shallow water, including disturbed places. It is an annual herb producing tufts of very thin, erect stems which reach about 30 centimeters in maximum height. The leaves sheath the stems and have short, narrow blades. The inflorescence is a cluster of several spikelets accompanied by a long, stiff, stemlike bract.
Cyperus laxus is a sedge species in the Cyperaceae. It is native to tropical regions of the Western Hemisphere and also to Africa. The species is reportedly naturalized in Assam and the Andaman and Nicobar Islands.
Schoenoplectiella hallii is a species of flowering plant in the sedge family known by the common name Hall's bulrush. It is native to the United States, where it has a disjunct distribution, occurring in widely spaced locations throughout the Midwest and East. It is a rare plant.
