Joseph Zu Salm-Reifferscheidt-Dyck
Joseph Franz Maria Anton Hubert Ignatz Fürst und Altgraf zu Salm-Reifferscheidt-Dyck (4 September 1773 at Castle Dyck near Neuss – 21 March 1861 in Nice) was a German aristocrat, amateur botanist and owner of Castle Dyck. Early life Joseph Franz was a member of the Salm-Reifferscheid-Dyck line of the House of Salm, an important aristocratic family that had ruled a small territory until the mediatisation of small German states in the early 19th century. He was the eldest surviving son of Count Franz Johann Wilhelm von Salm-Reifferscheidt-Dyck (1714–1775) and his wife, Countess Auguste von Waldburg zu Zeil und Wurzach (1743–1776). Biography After his training at the Jesuit College in Cologne, he traveled to Vienna, Brussels and Paris for private academic studies.

He regularly used his stays ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Genus, 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. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti ...

Uspallata
Uspallata is a village and administrative district in Argentina, in a scenic location on the road that crosses the Andes between Mendoza and Santiago in Chile. It is located west of Mendoza and was once served by the now disused Transandine Railway which passed through the town on its way from Mendoza to Los Andes in Chile. Features There are several items of interest in and around the village including "las bovedas," somewhat strangely egg-shaped kilns dating from the early 17th century which were used to extract gold, silver, zinc, copper and other metals from minerals mined nearby. Worth a brief visit as they are only approx from town, complete with a small museum, notes include the fact that some of the refractory bricks can still be seen with "Rufford Stourbridge" from the English West Midlands stamped on them; a brief reminder of Britain's industrial heritage. The road to the Chilean border incorporates some of the most dramatic scenery in the region, the Andean mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Huntington Desert Garden
The Huntington Desert Garden is part of The Huntington Library, Art Collections and Botanical Gardens in San Marino, California. The Desert Garden is one of the world's largest and oldest collections of cacti, succulents and other desert plants, collected from throughout the world. It contains plants from extreme environments, many of which were acquired by Henry E. Huntington and William Hertrich (the garden's first curator) in trips taken to several countries in North, Central and South America. History One of the Huntington Library's most botanically important gardens, the Desert Garden brought together a group of plants that were largely unknown and unappreciated in the early 1900s. Featuring a broad category of xerophytes (aridity-adapted plants), the Desert Garden grew to preeminence and remains today among the world's finest, with more than 5,000 species in the 10 acre (4 ha) garden.

Cereeae
Cereeae is a tribe of cacti belonging to the subfamily Cactoideae containing about 50 genera, divided in 2023 among six subtribes. Description Cereeae are tree-like or shrubby, sometimes climbing plants. Their mostly elongated to spherical, ribbed and thorny shoots are not articulated. The flowers, which usually appear on the side of the shoot, open during the day or at night. Their pericarpels usually have a few scales or are completely glabrous. The fleshy, berry-like, bursting or non-bursting fruits often have a blackening adherent flower remnant. The small to large seeds are oval. The hilum and micropyle of the seeds are fused, one appendage is absent. Taxonomy Phylogeny In classifications before the use of molecular phylogenetic methods, Cereeae was one of nine tribes into which the subfamily Cactoideae was divided. Molecular studies found that these traditional tribes were not monophyletic. A broader circumscription of Cereeae, including Browningieae and Trichocereeae and ...

Endemic Flora Of Argentina
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
