Cyperus Dives
''Cyperus dives'' is a plant in the genus ''Cyperus'' of the sedge family, Cyperaceae, which is found from south-west Syria to Africa, and from Pakistan to Vietnam. The SANBI Red List of South African Plants assessed its conservation status as being of "Least Concern" in 2006. Description Protologue "Sa tige est lisse, triangulaire, haute de 13 à 16 décimètres à 5 pieds Ses feuilles radicales sont longues d'environ un mètre pieds rudes à leur sommet, sur leurs bords, leur nervure dorsale, et vers leurs sommet sur deux nervures principales de leur face supérieure, où elles sont aiguillonnées par des dents très fines. Les rayons d'ombrelle sont au nombre de cinq à dix; les plus grands ont 15 centimètres de longueur nviron 6 pouces "Les feuilles extérieures de l'involucre sont longues d'environ 3 à 6 décimètres n ou deux pieds et sont rudes et finement aiguillonnées de la même manière que les feuilles radicales.

Pierre-Joseph Redouté
Pierre-Joseph Redout̩ (, 10 July 1759 Р19 June 1840), was a painter and botanist from Belgium, known for his watercolours of roses, lilies and other flowers at the Ch̢teau de Malmaison, many of which were published as large, coloured stipple engravings. He was nicknamed "the Raphael of flowers" and has been called the greatest botanical illustrator of all time.Schmidt, Alesandra M., and Trudy B. Jacoby"Herbs to Orchids: Botanical Illustration in the Nineteenth Century" Watkinson Exhibition Catalogs, Paper 3, 1996. Redout̩ was an official court artist of Marie Antoinette, and continued painting through the French Revolution and Reign of Terror. He survived the turbulent political upheaval to gain international recognition for his precise renderings of plants, which remain as fresh in the early 21st century as when first painted. He combined great artistic skills with a pleasing, ingratiating personality which assisted him with his influential patrons. After Queen Marie- ...

Alire Raffeneau Delile
Alire Raffeneau Delile (23 January 1778, in Versailles – 5 July 1850, in Montpellier) was a French botanist. Biography Delile studied botany with Jean Lemonnier, and was in the Paris medical school in 1796. Egypt Delile participated in Napoleon Bonaparte's Egypt Campaign where he described Lotus and Papyrus. Director of the Cairo botanical garden, he wrote the botanical sections of ''Travel in Lower and Upper Egypt'' by Dominique Vivant. He made a cast of the Rosetta Stone which allowed the reproduction of its Greek and Demotic inscriptions in his ''Description de l'Égypte''. United States In 1802, Delile was appointed French vice consul at Wilmington, North Carolina, and also asked to form an herbarium of all American plants that could be naturalized in France. He sent to Paris several cases of seeds and grains, and discovered some new graminea and presented them to Palisot de Beauvois, who described them in his ''Agrostographie''. Raffeneau made extensive explorations throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide an alternative food source for ...

Sedge
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. In comparison, g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nile Delta
The Nile Delta ( ar, دلتا النيل, or simply , is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers of Mediterranean coastline and is a rich agricultural region. From north to south the delta is approximately in length. The Delta begins slightly down-river from Cairo. Geography From north to south, the delta is approximately in length. From west to east, it covers some of coastline. The delta is sometimes divided into sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta had several distributaries, but these have been lost due to flood control, silting and changing relief. One such defunct distributary is Wadi Tumilat. The Suez Canal is east of the delta and enters the coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GBIF
The Global Biodiversity Information Facility (GBIF) is an international organisation that focuses on making scientific data on biodiversity available via the Internet using web services. The data are provided by many institutions from around the world; GBIF's information architecture makes these data accessible and searchable through a single portal. Data available through the GBIF portal are primarily distribution data on plants, animals, fungi, and microbes for the world, and scientific names data. The mission of the GBIF is to facilitate free and open access to biodiversity data worldwide to underpin sustainable development. Priorities, with an emphasis on promoting participation and working through partners, include mobilising biodiversity data, developing protocols and standards to ensure scientific integrity and interoperability, building an informatics architecture to allow the interlinking of diverse data types from disparate sources, promoting capacity building and catal ...

Taxa Named By Alire Raffeneau Delile
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
