William Aiton
William Aiton (17312 February 1793) was a Scotland, Scottish botanist. Aiton was born near Hamilton, Scotland, Hamilton. Having been regularly trained to the profession of a gardener, he travelled to London in 1754, and became assistant to Philip Miller, then superintendent of the Chelsea Physic Garden. In 1759 he was appointed director of the newly established Royal Botanic Gardens, Kew, botanical garden at Kew, where he remained until his death. He effected many improvements at the gardens, and in 1789 he published ''Hortus Kewensis'', a catalogue of the plants cultivated there. He is buried at nearby St. Anne's Church, Kew. A second and enlarged edition of the ''Hortus'' was brought out in 1810–1813 by his eldest son, William Townsend Aiton. Aiton is commemorated in the Specific epithet (botany), specific epithet ''aitonis''. In 1789, he classified the Sampaguita plant to the ''Jasmine, Jasminium'' genus and also named it as ''Arabian Jasmine'' because it was believed th ...

Catalogue Of Life
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological environment.

Crassulaceae
The Crassulaceae (from Latin ''crassus'', thick), also known as the stonecrop family or the orpine family, are a diverse family of dicotyledon flowering plants characterized by succulent leaves and a unique form of photosynthesis, known as Crassulacean acid metabolism (CAM). Flowers generally have five floral parts. Crassulaceae are usually herbaceous but there are some subshrubs, and relatively few treelike or aquatic plants. Crassulaceae are a medium size monophyletic family in the core eudicots, among the order Saxifragales, whose diversity has made infrafamilial classification very difficult. The family includes approximately 1,400 species and 34–35 genera, depending on the circumscription of the genus ''Sedum'', and distributed over three subfamilies. Members of the Crassulaceae are found worldwide, but mostly in the Northern Hemisphere and southern Africa, typically in dry and/or cold areas where water may be scarce, although a few are aquatic. Crassulaceae are mainly pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Madeira Island
Madeira is a Portuguese island, and is the largest and most populous of the Madeira Archipelago. It has an area of , including Ilhéu de Agostinho, Ilhéu de São Lourenço, Ilhéu Mole (northwest). As of 2011, Madeira had a total population of 262,456. The island is the top of a massive submerged shield volcano that rises about from the floor of the Atlantic Ocean. The volcano formed atop an east–west rift in the oceanic crust along the African Plate, beginning during the Miocene epoch over 5 million years ago, continuing into the Pleistocene until about 700,000 years ago. This was followed by extensive erosion, producing two large amphitheatres open to south in the central part of the island. Volcanic activity later resumed, producing scoria cones and lava flows atop the older eroded shield. The most recent volcanic eruptions were on the west-central part of the island only 6,500 years ago, creating more cinder cones and lava flows. Madeira is the largest is ...

Desertas Islands
The Desertas Islands ( pt, Ilhas Desertas, , "Deserted Islands") are a small archipelago in the Atlantic Ocean, part of the larger Portuguese Madeira Archipelago. The archipelago is located off the coast of Morocco. Deserta Grande Island is located about southeast of the eastern tip of Madeira Island, Ponta de São Lourenço. Geography The archipelago of the Desertas Islands is a chain of three long and narrow islands that stretch over a north/south distance of . The Desertas Islands, from north to south with approximate area figures, are: Administration Administratively, the islands are part of the Municipality of Santa Cruz in Madeira, and in the Santa Cruz civil parish. The islands are a designated Portuguese nature reserve. A licence is needed to land there. Natural history Though near the main island of Madeira, where the islands can often be seen on the horizon, the geology of the Ilhas Desertas is starkly different. The high, long, and rocky islands of the group ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Levadas
A levada is an irrigation channel or aqueduct specific to the Portuguese Atlantic region of Madeira. History In Madeira, the levadas originated out of the necessity of bringing large amounts of water from the west and northwest of the island to the drier southeast, which is more conducive to habitation and agriculture, such as sugar cane production. They were used in the past also by women to wash clothes in areas where running water to homes was not available. The idea of this style of water channel was brought to Portugal by the Moors during the time of al-Andalus (dubious) . Similar examples can still be found in Iberia, such as some Acequias in Spain. In the sixteenth century the Portuguese started building levadas to carry water to the agricultural regions. The most recent were made in the 1940s. Madeira is very mountainous, and building the levadas was often difficult. Many are cut into the sides of mountains, and it was also necessary to dig of tunnels. Levadas to ...

Aichryson
''Aichryson'' is a genus of about 15 species of succulent, subtropical plants, mostly native to the Canary Islands, with a few in the Azores, Madeira and Morocco. The species of ''Aichryson'' are not frost-resistant. They are related to ''Sempervivum, Jovibarba, Greenovia, Aeonium'' and ''Monanthes'', readily seen in their similar flowers. The genus name comes from a contraction of the Greek "aei" (always) and "chrysos" (gold). Several species are cultivated as ornamental plants. The hybrid cultivar ''Aichryson'' × ''aizoides'' var. ''domesticum'' 'Variegatum' is a recipient of the Royal Horticultural Society's Award of Garden Merit. Taxonomy Recent phylogenetic studies of Crassulaceae indicate that ''Aichryson'' is closely related to ''Monanthes'' and ''Aeonium'' (both genera are also largely endemic to the Canary Islands). Two other genera of Crassulaceae that have many-parted (polymerous) flowers (''Sempervivum'' and ''Jovibarba ''Jovibarba'' ("beard of Jupiter") is a ...
