Carex Subg. Carex
''Carex'' subg. ''Carex'' is a subgenus of the sedge genus '' Carex''. It is the largest of the four traditionally recognised subgenera, containing around 1400 of the 2000 species in the genus. Its members are characterised by the presence of one or more exclusively male (staminate) terminal spikes, quite dissimilar in appearance from the lateral female (pistillate) spikes below. In most species, the female flowers have three stigmas, but a few species, including ''Carex nigra ''Carex nigra'' is a perennial species of plants in the family Cyperaceae native to wetlands of Europe, western Asia, northwestern Africa, and eastern North America. Common names include common sedge, black sedge or smooth black sedge. The easte ...'', have female flowers with only two stigmas.

Carex Riparia
''Carex riparia'', the greater pond sedge, is a species of sedge found across Europe and Asia. It grows in a variety of wet habitats, and can be a dominant species in some swamps. It is Britain's largest ''Carex'', growing up to tall, with glaucous leaves up to long. It hybridises with a number of other ''Carex'' species, including the closely related ''Carex acutiformis'' – the lesser pond sedge. A variegated cultivar is grown as an ornamental grass. Distribution and habitat ''Carex riparia'' has a broad distribution over Europe and Western and Central Asia, with isolated occurrences in North Africa. It can form large stands along slow-flowing rivers, canals, on the edges of lakes, and in wet woodland. It may be the dominant species in swamps, especially if there is standing water in spring, and is also found in tall-herb fens, alongside ''Carex acutiformis'', ''Carex acuta'' and other similar species.

Carex Hirta
''Carex hirta'', the hairy sedge or hammer sedge, is a species of sedge native across Europe. It has characteristic hairy leaves and inflorescences, and is the type species of the genus ''Carex''. Description ''Carex hirta'' grows tall, with leaves long and (occasionally up to ) wide. The stems are trigonous (roughly triangular in cross-section), but with convex, rounded faces. The leaves, leaf sheaths and ligules are all hairy, although plants growing in wetter positions may be less hairy; these have sometimes been separated as ''C. hirta'' var. ''sublaevis'' by Jens Wilken Hornemann, but this may not be a worthwhile taxon. The culms bear 2–3 lateral female spikes, each long, and on half-ensheathed peduncles up to twice the length of the spike. There are 2–3 male spikes at the end of the culm, each long. The hairy utricles, male glumes and leaves make it hard to confuse ''Carex hirta'' with any other ''Carex'' species. Distribution ''Carex hirta'' is native to Europ ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

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] |

Spike (botany)
A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers. The oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. Examples of racemes occur on mustard (genus ''Brassica'') and radish (genus ''Raphanus'') plants. Definition A ''raceme'' or ''racemoid'' is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers (flowers having short floral stalks called ''pedicels'') along its axis. In botany, an ''axis'' means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers grow close to the base and new flowers are produced as the shoot grows in height, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. the species ''Cimicifuga racemosa''. A compou ...

List Of Carex Species
The genus ''Carex'', the sedges, is one of the largest genera of flowering plants, containing around 1800 species, according to a 2004 estimate. All the species (including hybrid species) accepted by '' The Plant List'' are given below: In May 2015, the Global Carex Group argued for a broader circumscription of Carex, proposing the addition of all species currently classified in ''Cymophyllus'' (1 species), ''Kobresia'' (c. 60 species), ''Schoenoxiphium'' (c. 15 species) and ''Uncinia'' (c. 70 species) to those already classified as ''Carex''.
