Schlumbergera Russelliana (Epiphyllum Russellianum) Bot
''Schlumbergera russelliana'' is a species of plant in the family Cactaceae. It is endemic to a small area of the coastal mountains of south-eastern Brazil where its natural habitat is moist forest. It grows on trees as an epiphyte. It is one of the parents of many of the popular houseplants known as Christmas cactus or Thanksgiving cactus. Description ''Schlumbergera russelliana'' resembles other species of the genus ''Schlumbergera'' in that it has leafless green stems which act as photosynthetic organs. The stems (cladodes) are composed of strongly flattened segments, which have a small number of notches along their edges. Individual segments are about long by wide. Special structures characteristic of cacti, called "areoles", occur in the notches at the side of a segment and at the end. The areoles, which bristles up to long, are where the flower buds appear. The flowers hang downwards and are radially symmetrical (regular). They are about long by across. The tepals, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

John Russell, 6th Duke Of Bedford
John Russell, 6th Duke of Bedford, (6 July 1766 – 20 October 1839), known as Lord John Russell until 1802, was a British Whig politician who notably served as Lord Lieutenant of Ireland in the Ministry of All the Talents. He was the father of Prime Minister John Russell, 1st Earl Russell. Background Bedford was a younger son of Francis Russell, Marquess of Tavistock, eldest son and heir of John Russell, 4th Duke of Bedford. His mother was Lady Elizabeth, the youngest child of Willem van Keppel, 2nd Earl of Albemarle and Lady Anne Lennox. Political career Like most Russells, Bedford was a Whig in politics. He sat as Member of Parliament for Tavistock from 1788 to June 1790 and from December 1790 to 1802, when he was automatically elevated to the Lords on the death of his brother. He served as Lord Lieutenant of Ireland during the Whig government of 1806–1807. He became, as did many of his party who were strong followers of Bonapartism, opposed to the Peninsular War, be ...

'' Cultivation
In formal language theory, the empty string, or empty word, is the unique string of length zero. Formal theory Formally, a string is a finite, ordered sequence of characters such as letters, digits or spaces. The empty string is the special case where the sequence has length zero, so there are no symbols in the string. There is only one empty string, because two strings are only different if they have different lengths or a different sequence of symbols. In formal treatments, the empty string is denoted with ε or sometimes Λ or λ. The empty string should not be confused with the empty language ∅, which is a formal language (i.e. a set of strings) that contains no strings, not even the empty string. The empty string has several properties: * , ε, = 0. Its string length is zero. * ε ⋅ s = s ⋅ ε = s. The empty string is the identity element of the concatenation operation. The set of all strings forms a free monoid with respect to ⋅ and ε. * εR = ε. Reversal of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schlumbergera Orssichiana
''Schlumbergera orssichiana'' is a species of plant in the family Cactaceae. It is endemic to a small area of the coastal mountains of south-eastern Brazil where its natural habitat is moist forest. It grows on trees as an epiphyte. It is in the same genus as the popular houseplant known as Christmas cactus or Thanksgiving cactus. Description ''Schlumbergera orssichiana'' resembles other species of the genus ''Schlumbergera'' in that it has leafless green stems which act as photosynthetic organs. The stems (cladodes) are composed of strongly flattened segments, which have "teeth" of varying shapes along their edges, where there are generally two to three, and at the ends. Individual segments are large, long by wide. Special structures characteristic of cacti, called "areoles", occur at the end of the segments. The areoles are where the flower buds appear. The large flowers, which open widely, are held at a slight angle to the vertical, with the higher side somewhat different ...

Schlumbergera Truncata
''Schlumbergera truncata'', the false Christmas cactus, is a species of plant in the family Cactaceae. It is endemic to a small area of the coastal mountains of south-eastern Brazil where its natural habitats are subtropical or tropical moist forests. It is the parent or one of the parents of the houseplants called Christmas cactus, Thanksgiving cactus or zygocactus, among other names. Description ''Schlumbergera truncata'' resembles other species of the genus ''Schlumbergera'' in that it has leafless green stems which act as photosynthetic organs. The stems (cladodes) are composed of strongly flattened segments, which have two or three "teeth" of varying shapes along their edges and at the ends. The ends of the stems are "cut off" (truncated) rather than pointed. Individual segments are about long by wide. Special structures characteristic of cacti, called "areoles", occur between two teeth at the end of segments. The areoles, which have brown wool and bristles up to long ...

Schlumbergera Buckleyi WPC3
''Schlumbergera'' is a small genus of cacti with six to nine species found in the coastal mountains of south-eastern Brazil. These plants grow on trees or rocks in habitats that are generally shady with high humidity, and can be quite different in appearance from their desert-dwelling cousins. Most species of ''Schlumbergera'' have stems which resemble leaf-like pads joined one to the other and flowers which appear from areoles at the joints and tips of the stems. Two species have cylindrical stems more similar to other cacti. Recent phylogenetic studies using DNA have led to three species of the related genus ''Hatiora'' being transferred into ''Schlumbergera,'' though this change is not universally accepted. Common names for these cacti generally refer to their flowering season. In the Northern Hemisphere, they are called Christmas cactus, Thanksgiving cactus, crab cactus and holiday cactus. In Brazil, the genus is referred to as (May flower), reflecting the period in which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphyte
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Charles Antoine Lemaire
Charles Antoine Lemaire (1 November 1800, in Paris – 22 June 1871, in Paris), was a French botanist and botanical author, noted for his publications on Cactaceae. Education Born the son of Antoine Charles Lemaire and Marie Jeanne Davio, he had an excellent early education, and acquired the reputation of being an outstanding scholar. He studied at the University of Paris and was appointed as Professor of Classical Literature there. At some stage his botanical interest was sparked and developed by his association with M. Neumann, horticulturist at the Muséum national d'histoire naturelle, Museum of Natural History. Career He worked for some time as an assistant to M. Mathieu, at a nursery in Paris, building up a collection of Cactaceae, a group to which he would devote almost all of his life. In 1835, M. Cousin, a Parisian publisher, started a gardening journal and requested that he be its editor. For a number of years, he remained editor of ''Jardin Fleuriste'' and ''L'Horticu ...
