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.

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.
Fimbristylis is a genus of sedges. A plant in this genus may be known commonly as a fimbry or fimbristyle. 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.
Carex echinata is a species of sedge known by the common names star sedge and little prickly sedge.
Carex nigra is a perennial species of plants in the family Cyperaceae native to wetlands of Europe, western Asia, north Africa, and eastern North America. Common names include common sedge, black sedge or smooth black sedge. The eastern limit of its range reaches central Siberia, Turkey and probably the Caucasus.
Georg Kükenthal was a German pastor and botanist who specialized in the field of caricology. He was the brother of zoologist Willy Kükenthal (1861–1922).
In botany, a perigynium, also referred to as a utricle, typically refers to a sac that surrounds the achene of plants in the genus Carex (Cyperaceae). The perigynium is a modified prophyll, tissue of leaf origin, that encloses the dry, one-seeded achene.
Carex sect. Spirostachyae is a section of the genus Carex, containing 38 species of sedge. Species in Carex sect. Spirostachyae share a suite of features, including the short internodes of the primary rhizomes, the presence of an antiligule, the leaf-like, sheathing bract at the base of the inflorescence, the presence of three stigmas in female flowers, and the shape of the seeds.
Carex subg. Vignea is a subgenus of the sedge genus Carex, containing around 300 of the 2000 species in the genus. Its members are characterised by having bisexual, sessile spikes, where the female flowers have two stigmas each.
Carex accrescens is a species of sedge that was first described by Jisaburo Ohwi in 1931. It is native to eastern Asia, from Siberia to the Korean Peninsula and Japan.
Carex erebus is a member of the sedge family and is found on the Antarctic Islands of Australia and New Zealand.
Peter William Ball is an English-born botanist, plant collector, and plant taxonomist, specializing in caricology.
Carex remota, the remote sedge, is a species in the genus Carex, native to Europe, the Atlas Mountains in Africa, and western Asia. It is a riparian forest specialist. It is known as one of the most frequently hybridizing species of Carex, forming hybrids with C. appropinquata, C. arenaria, C. brizoides, C. canescens, C. divulsa, C. echinata, C. elongata, C. leporina, C. otrubae, C. paniculata, and C. spicata.
Carex flava, called hedgehog grass, is a widespread species of sedge, native to the northern United States, Canada, Iceland, Europe, the Atlas Mountains in Africa, the Transcaucasus area, and parts of Siberia. It is the namesake of the Carex flava species complex.
Carex demissa is a species of sedge, native to Iceland, Macaronesia, all of Europe, and western Asia to the Himalayas and possibly Greenland. It has been introduced to eastern Canada, New Jersey, and Tasmania. It is a member of the Carex flava species complex.
Carex lepidocarpa, called the long-stalked yellow-sedge, is a species of flowering plant in the genus Carex, native to eastern Canada, Morocco, and most of Europe. It is a member of the Carex flava species complex.
Schoenus inconspicuus is a species of sedge endemic to south-western areas of the Western Cape Province of South Africa.
