Pyrostria Revoluta
''Pyrostria revoluta'', formerly ''Scyphochlamys revoluta'', is a species of flowering plant in the Family (biology), family Rubiaceae that lives on the island of Rodrigues. Distribution and conservation ''Pyrostria revoluta'' is found on Rodrigues, one of the Mascarene Islands in the Indian Ocean, and an Outer islands of Mauritius, Outer island of Mauritius. By 1980, it appeared to be restricted to Grande Montagne and Cascade Victoire, and by 1989, the species was considered to be "on the verge of extinction". Some seeds were sent to the Royal Botanic Gardens, Kew, where they were successfully germinated in 1982 and subsequently grown up. Cutting (plant), Cuttings have since been taken, effectively ensuring the species' survival in cultivation. Description ''Pyrostria revoluta'' is a shrub or small tree, at up to tall. The leaves are notably dimorphic – they grow in two distinctly different forms. Juvenile leaves are up to long, but only wide. Mature leaves are a similar l ...

Isaac Bayley Balfour
Sir Isaac Bayley Balfour, KBE, FRS, FRSE (31 March 1853 – 30 November 1922) was a Scottish botanist. He was Regius Professor of Botany at the University of Glasgow from 1879 to 1885, Sherardian Professor of Botany at the University of Oxford from 1884 to 1888, and Professor of Botany at the University of Edinburgh from 1888 to 1922. Early life He was the son of John Hutton Balfour, also a botanist, and Marion Spottiswood Bayley, and was born at home, 27 Inverleith Row, Edinburgh. His mother was granddaughter of George Husband Baird. He was the cousin of Sir James Crichton-Browne. Biography Balfour was educated at the Edinburgh Academy from 1864 to 1870. At this early stage his interests and abilities were in the biological sciences, which were taught to him by his father. Due to his father's post as Professor of Botany at Edinburgh, the young Balfour was able to visit the Edinburgh Botanical Gardens, not open to the public at the time. Balfour studied at the University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1877
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 abilit ...

Endemic Flora Of Rodrigues
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanguerieae
Vanguerieae is a tribe of flowering plants in the family Rubiaceae and contains about 655 species in 30 genera. It is one of the most species-rich groups within the family and it is distributed across the Paleotropics. Description Several different life forms are present in the tribe: most species are shrubs, but geofructices (plants with woody rhizomes) (e.g. ''Fadogia homblei'', ''Pygmaeothamnus zeyheri''), small trees (e.g. ''Vangueria infausta''), and climbers (e.g. ''Keetia gueinzii'') also occur. As all Rubiaceae species, the leaves are opposite, simple and entire, and they have interpetiolar stipules. The phyllotaxis is decussate, sometimes conspicuously so (e.g. ''Canthium inerme''), and rarely whorled (e.g. ''Fadogia''). Some species have spines (e.g. ''Canthium''). Secondary pollen presentation is characteristic for the tribe and the species develop a conspicuous “stylar head”-complex, which is a structural unit consisting of a pollen presenting organ combined with ...

Henry Horrocks Slater
Henry Horrocks Slater (1851–26 November 1934) was an English parson-naturalist who studied ornithology, entomology, and botany. Early life and clerical career Slater was born in Stanhope, County Durham, the son of the priest Henry Slater and his wife Mary Sarah Horrocks. He was matriculated at St Catharine's College, Cambridge in 1870, and graduated as a Bachelor of Arts in 1880 (made Master of Arts in 1887). In 1879 he was ordained a deacon in Ripon, West Riding of Yorkshire. In 1881 he was ordained as a priest.

George Gulliver
George Gulliver (4 June 1804 – 17 November 1882), was an English anatomist and physiologist. Life and work Gulliver was born at Banbury, Oxfordshire, on 4 June 1804, and after an apprenticeship with local surgeons entered at St. Bartholomew's Hospital, London, where he became prosector to Abernethy and dresser to Lawrence (afterwards Sir William). Becoming a Member of the Royal College of Surgeons in June 1826 he was gazetted hospital assistant to the forces in May 1827, and afterwards became surgeon to the Royal Horse Guards (the Blues). He was elected a Fellow of the Royal Society in 1838, Fellow of the Royal College of Surgeons in 1843, and in 1852 a member of the council of the latter body. In 1861 he was Hunterian professor of comparative anatomy and physiology, and in 1863 delivered the Hunterian oration, in which he strongly put forward the neglected claims of William Hewson and John Quekett as discoverers. For some years before his death he had retired from the arm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Of Venus, 1874
The 1874 transit of Venus, which took place on 9 December 1874 (01:49 to 06:26 UTC), was the first of the pair of transits of Venus that took place in the 19th century, with the second transit occurring eight years later in 1882. The previous pair of transits had taken place in 1761 and 1769, and the next pair would not take place until 2004 and 2012. As with previous transits, the 1874 transit would provide an opportunity for improved measurements and observations. Numerous expeditions were planned and sent out to observe the transit from locations around the globe, with several countries setting up official committees to organise the planning. There were six official French expeditions. One expedition went to New Zealand's Campbell Island, the other five travelling to Île Saint-Paul in the Indian Ocean, Nouméa in New Caledonia in the Pacific, Nagasaki in Japan (with an auxiliary station in Kobe), Peking in China, and Saigon in Vietnam. There were five official British ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pyrostria
''Pyrostria'' is a genus of dioecious flowering plants in the family Rubiaceae. Most of the species are endemic to Madagascar, others occur on islands in the western Indian Ocean (Mauritius, Comoros, Réunion, Rodrigues, Socotra), a few are found in continental Africa, and only six species occur in tropical Southeast Asia. The formerly recognized genus ''Leroya'', containing two species endemic to Madagascar, ''L. madagascariensis'' and ''L. richardiae'', was sunk into synonymy with ''Pyrostria''.

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...
