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.
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.
Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions.
Cyperus rotundus is a species of sedge (Cyperaceae) native to Africa, southern and central Europe, and southern Asia. The word cyperus derives from the Greek κύπερος, kyperos, and rotundus is from Latin, meaning "round". The earliest attested form of the word cyperus is the Mycenaean Greek 𐀓𐀞𐀫, ku-pa-ro, written in Linear B syllabic script.
Cyperus alternifolius, the umbrella papyrus, umbrella sedge or umbrella palm, is a grass-like plant in the very large genus Cyperus of the sedge family Cyperaceae. The plant is native to West Africa, Madagascar and the Arabian Peninsula, but widely distributed throughout the world. It has gained the Royal Horticultural Society's Award of Garden Merit. The subspecies Cyperus alternifolius ssp. flabelliformis is also known as Cyperus involucratusRottb..
Cyperus polystachyos, also known as Pycreus polystachyos, and also called manyspike flatsedge in the US, or bunchy sedge, coast flatsedge, many-spiked sedge or Texas sedge in Australia, is a herbaceous species in the family Cyperaceae, widespread in tropical and subtropical areas around the world, sometimes extending its range into temperate regions.
Cyperus eragrostis is a species of sedge known by several common names, including tall flatsedge, nutgrass, tall nutgrass, umbrella sedge, chufa, Earth almond, zula nuts, edible galingale and pale galingale.
Cyperus erythrorhizos is a species of sedge known by the common names red-rooted flatsedge or redroot flatsedge. It is found across much of North America from Maine, Ontario and British Columbia south to Tabasco in southern Mexico.
Cyperus fuscus is a species of sedge known by the common name brown galingale, or brown flatsedge. This plant is native to much of Europe, Asia and North Africa from England, Portugal and Morocco east to China and Thailand. It is an introduced species in North America, where it is naturalized in widely scattered locations in the United States and Canada.
Cyperus niger is a species of sedge known by the common name black flatsedge. This plant is native to the Americas, where it can be found in wet areas from South and Central America to the southwestern United States, from California and Oklahoma south to Argentina.
Cyperus odoratus is a species of sedge known by the common names fragrant flatsedge and rusty flatsedge. This plant can be found in much of the tropical and warm temperate world, including South, Central, and North America, Southeast Asia, some Pacific Islands, Australia, New Guinea, Madagascar, and central Africa. It is a plant of wet, muddy areas, including disturbed and altered sites. This species is quite variable and may in fact be more than one species included under one name. In general this is an annual plant approaching half a meter in height on average but known to grow much taller. It usually has some long, thin leaves around the base. The inflorescence is made up of one to several cylindrical spikes attached at a common point. Each of the spikes bears a large number of flat, oval-shaped spikelets. Each spikelet is usually light brown to reddish-brown and has a few to over 20 flowers. Each flower is covered by a tough, flat bract with a visible midvein. The fruit is a flat achene less than two millimeters long.
Cyperus squarrosus is a species of sedge known by several common names, including bearded flatsedge and awned flatsedge. It is found in wet environments in North and South America, Africa, Australia, southern Asia and Italy.
Cyperus laevigatus is a species of sedge known by the common name smooth flatsedge.
Cyperus echinatus is a species of plant in the sedge family. It is native to much of the eastern United States, primarily in the lower Mississippi Valley and the lowland plain east of the southern Appalachians, with scattered populations in Florida and as far north as Wisconsin and the Adirondacks. Additional isolated populations occur in southern Mexico. It is found in a variety of sunny, often mesic habitats.
Cyperus gracilis, with the common name is slender flat sedge and slimjim flatsedge, is a sedge native to Australia. The species epithet gracilis refers to the graceful form of the leaves.
Cyperus articulatus is an aromatic species of sedge known by the common names jointed flatsedge and priprioca. It has also been known as Guinea rush or adrue. It grows as a perennial herb. It grows in water or near it in rivers, streams, lakes, and swamps with a hyperhydrate or possibly tenagophyte growth pattern. It is widespread across tropical and subtropical regions in Africa, southern Asia, northern Australia, the southeastern United States, the West Indies, and Latin America. While it is closely related to highly invasive sedges such as purple nut sedge, priprioca is less prolific and competitive than its relative.
Bulrush is a vernacular name for several large wetland grass-like plants
Cyperus javanicus, also known as the Javanese flatsedge, is a sedge of the family Cyperaceae that is native to Indonesia and Australia.
Cyperus flavescens, commonly known as the yellow flatsedge, is a species of flowering plant belonging to the family Cyperaceae.
