Cyperaceae
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. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks.

Carex
''Carex'' is a vast genus of more than 2,000 species of grass-like plants in the family Cyperaceae, commonly known as sedges (or seg, in older books). 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. Description All species of ''Carex'' are perennial, although some species, such as '' C. bebbii'' and '' C. viridula'' can fruit in their first year of growth, and may not survive longer. They typically have rhizomes, stolons or short rootstocks, but some species grow in tufts (caespitose). The culm – the flower-bearing stalk – is unbranched and usually erect. It is usually distinctly triangular in section. The leaves of ''Carex'' comprise a blade, which extends away from the stalk, and a sheath, which encloses part of the stalk. The blade is normally long and flat, but may be folded, inrolled, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiscirpus
''Amphiscirpus'' is a monotypic genus of flowering plants in the sedge family containing the single species ''Amphiscirpus nevadensis'', which is known by the common name Nevada bulrush. This plant was formerly included in genus ''Scirpus''.Goetghebeur, P. and D. A. Simpson. (1991). Critical notes on ''Actinoscirpus'', ''Bolboschoenus'', ''Isolepis'', ''Phylloscirpus'' and ''Amphiscirpus'' (Cyperaceae). ''Kew Bulletin'' 46:1 169-78. It is native to western North America, including the western Canadian provinces and the northwestern United States, as well as southern South America. It grows in wet and seasonally wet habitat, often on saline and alkaline soils. It is a perennial herb growing from a small, hard rhizome. The erect stems are stiff, ridged, and cylindrical, not three-angled. It lacks aerenchyma, a trait which makes it different from many of its relatives. The stems are sheathed by tough long leaves. The inflorescence is a headlike cluster of a few cone-shaped spikelet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperus Rotundus
''Cyperus rotundus'' (coco-grass, Java grass, nut grass, purple nut sedge or purple nutsedge, red nut sedge, Khmer ''kravanh chruk''Martin, Robert & Pol Chanthy, 2009''Weeds of Upland Cambodia'', ACIAR Monagraph 141, Canberra.) is a species of sedge (Cyperaceae) native to Africa, southern and central Europe (north to France and Austria), and southern Asia. The word ''cyperus'' derives from the Greek , ''kyperos'', and ''rotundus'' is from Latin, meaning "round". The earliest attested form of the word ''cyperus'' is the Mycenaean Greek , ''ku-pa-ro'', written in Linear B syllabic script. Description ''Cyperus rotundus'' is a perennial plant, that may reach a height of up to . The names "nut grass" and "nut sedge" – shared with the related species ''Cyperus esculentus'' – are derived from its tubers, that somewhat resemble nuts, although botanically they have nothing to do with nuts. As in other Cyperaceae, the leaves sprout in ranks of three from the base of the plant, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleocharis
''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 (in the tropical Andes). The genus itself is relatively easy to recognize; all ''Eleocharis'' species have photosynthetic stems but no green leaves (the leaves have been reduced to sheaths surrounding the base of the stems). Many species are robust, rhizomatously ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eriophorum
''Eriophorum'' (cottongrass, cotton-grass or cottonsedge) is a genus of flowering plants in the family Cyperaceae, the sedge family. They are found throughout the arctic, subarctic, and temperate portions of the Northern Hemisphere in acid bog habitats, being particularly abundant in Arctic tundra regions.Flora Europaea''Eriophorum''/ref> They are herbaceous perennial plants with slender, grass-like leaves. The seed heads are covered in a fluffy mass of cotton-like fibers which are carried on the wind to aid dispersal. The cotton grass also maintains a height of 12 inches and around 2 inches in water. In cold Arctic regions, these masses of translucent fibres also serve as 'down' – increasing the temperature of the reproductive organs during the Arctic summer by trapping solar radiation. Paper and the wicks of candles have been made of its fiber, and pillows stuffed with the same material. The leaves were formerly used in treating diarrhea, and the spongy pith of th ...

Actinoscirpus
''Actinoscirpus'' is a monospecific genus in the family Cyperaceae which contains only the species ''Actinoscirpus grossus'', the greater club rush. It is found across East and South Asia and is known in China as 大藨草 (da biao cao), ''rumput menderong'' in Malaysian, and ''kasheruka'' within Ayurvedic medicine, which uses the tubers as an antiemetic and treatment for liver and digestive diseases. It is a perennial plant that grows rapidly with long rhizomes that end in small tubers. ''A. grossus'' is considered a "principal" weed of rice in some Southeast Asian countries. It is abundant in swampy or inundated areas, such as marshes and ditches, and is capable of dominating wetlands and rice patties. It is also a host of ''Chilo polychrysus'', the dark-headed rice borer. Description Stands of greater club rush grow to lengths of 1.5 to 2 meters. It grows well in both inundated lands and areas with flooding. Individuals grow in colonies with 10 to 15 centimeters between stem ...

Rhynchospora Colorata
''Rhynchospora colorata'', also known as starrush whitetop, white star sedge and white-topped sedge, is a perennial sedge with white bracts, giving it the appearance of white petals with long, green points. It is native to southeastern North America, from Virginia west to New Mexico in the United States, and south into the Caribbean islands. The inflorescence is a dense cluster of small spikes, each containing several tiny flower A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Angiospermae). The biological function of a flower is to facilitate reproduction, usually by providing a mechani ...s. It sits on top of 3–10 green and white bracts that grow to 10–15 cm long.

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Cladium
''Cladium'' (fen-sedge, sawgrass or twig-sedge) is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence. Like many plants found in wet habitats, it has deeply buried rhizomes that can produce tall shoots with dense canopies. ''Cladium mariscus ''subsp.'' jamaicense'', or saw-grass, is common in marshes and savannas throughout the tropical Americas. One typical and well-known area of extensive saw-grass growth is the Florida Everglades; sawgrass is the plant referred to by the descriptor, "River of Grass". Like many species of the Everglades, ''C. jamaicense'' grows in extremely infertile conditions, particularly wet sites that are low in phosphorus. Dense sawgrass beds are intermingled with other vegetation types. Together they produce a rich arr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperus Papyrus
''Cyperus papyrus'', better known by the common names papyrus, papyrus sedge, paper reed, Indian matting plant, or Nile grass, is a species of aquatic flowering plant belonging to the sedge family Cyperaceae. It is a tender herbaceous perennial, native to Africa, and forms tall stands of reed-like swamp vegetation in shallow water. Papyrus sedge (and its close relatives) has a very long history of use by humans, notably by the Ancient Egyptians (as it is the source of papyrus paper, one of the first types of paper ever made). Parts of the plant can be eaten, and the highly buoyant stems can be made into boats. It is now often cultivated as an ornamental plant. In nature, it grows in full sun, in flooded swamps, and on lake margins throughout Africa, Madagascar, and the Mediterranean countries. It has been introduced outside its range to tropical regions worldwide (such as the Indian subcontinent, South America, and the Caribbean). Description This tall, robust aquatic pl ...
