Alsophila × Boytelii
''Alsophila'' × ''boytelii'' is a tree fern endemic to the Sierra Maestra range of southeastern Cuba. It is a natural interspecific hybrid between '' Alsophila balanocarpa'' and ''Alsophila woodwardioides''. The spores of ''A.'' × ''boytelii'' are normal in appearance; Caluff and Serrano (2002) suggest that it might therefore be fertile. This theory is strengthened by the presence of a large population of ''A.'' × ''boytelii'' in the Gran Piedra area. Caluff and Serrano (2002) note that "a full range of intermediates linking this hybrid with its parent species suggests the occurrence of backcrossing". The type material was collected in Reserva Gran Piedra, Santiago de Cuba Province Santiago de Cuba Province is the second most populated province in the island of Cuba. The largest city Santiago de Cuba is the main administrative center. Other large cities include Palma Soriano, Contramaestre, San Luis and Songo-la Maya. Hi ... at an altitude of 1000 m ...

Cyatheales
The order Cyatheales, which includes most tree ferns, is a taxonomic order of the fern class, Polypodiopsida. No clear morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyletic. Some species in the Cyatheales have tree-like growth forms from a vertical rhizome, others have shorter or horizontal expanding rhizomes. Some species have scales on the stems and leaves, while others have hairs. However, most plants in the Cyatheales are tree ferns and have trunk-like stems up to tall. It is unclear how many times the tree form has evolved and been lost in the order.Judd, W.S., C.S. Campbell, E.A. Kellogg, P.F. Stevens, and M.J. Donoghue (Eds.) 2008.

Endemic (ecology)
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] |
Sierra Maestra
The Sierra Maestra is a mountain range that runs westward across the south of the old Oriente Province in southeast Cuba, rising abruptly from the coast. The range falls mainly within the Santiago de Cuba and in Granma Provinces. Some view it as a series of connecting ranges (Vela, Santa Catalina, Quemado Grande, Daña Mariana), which join with others to the west. At 1,974 m (6,476 ft), Pico Turquino is the range's – and the country's – highest point. The area is rich in minerals, especially copper, manganese, chromium, and iron. History The Sierra Maestra has a long history of guerrilla warfare, starting with the resistance of the Taínos under Guamá (died 1532), the Cimarrón Neo-Taíno nations escaped slave cultures, the Ten Years' War (1868–1878) and the Cuban War of Independence (1895–1898), and various minor conflicts such as the Race War of 1912, and the uprisings of Antonio Guiteras (died 1935) against Gerardo Machado (President of Cuba f ...

Cuba
Cuba ( , ), officially the Republic of Cuba ( es, República de Cuba, links=no ), is an island country comprising the island of Cuba, as well as Isla de la Juventud and several minor archipelagos. Cuba is located where the northern Caribbean Sea, Gulf of Mexico, and Atlantic Ocean meet. Cuba is located east of the Yucatán Peninsula (Mexico), south of both the American state of Florida and the Bahamas, west of Hispaniola ( Haiti/Dominican Republic), and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The official area of the Republic of Cuba is (without the territorial waters) but a total of 350,730 km² (135,418 sq mi) including the exclusive economic zone. Cuba is the second-most populous country in the Caribbean after Haiti, with over 11 million inhabitants. The territory that is now Cuba was inhabited by the Ciboney people from the 4th millennium BC with the Gua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interspecific Hybrid
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alsophila Balanocarpa
''Alsophila balanocarpa'', synonym ''Cyathea balanocarpa'', is a species of tree fern native to Cuba, Jamaica and Hispaniola. Despite its wide distribution, little is known about this species. It is apparently of hybrid origin.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reserva Gran Piedra
Reserve wine is wine of a higher quality than usual, a wine that has been aged before sale, or both. Traditionally, winemakers would reserve some of their best wine rather than sell it immediately, coining the term. In some countries the use of the term "reserve", "''reserva''" or "''riserva''" is regulated, but in many places it is not. According to Italian wine laws, ''riserva'' indicates additional aging. Sometimes, reserve wine originates from the best vineyards, or the best barrels. Reserve wines may be made in a style suited to longer aging periods. In regions where the use is not regulated, the presence of the term "reserve" on a wine label may be a marketing strategy, without specific criteria. In Kendall-Jackson Chardonnay, every bottle produced is "Vintner's Reserve", and to indicate a traditional reserve wine, Kendall-Jackson uses the term "Grand Reserve". Like the term "old vines", "reserve" traditionally indicates a wine that is special, or at least different in flav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santiago De Cuba Province
Santiago de Cuba Province is the second most populated province in the island of Cuba. The largest city Santiago de Cuba is the main administrative center. Other large cities include Palma Soriano, Contramaestre, San Luis and Songo-la Maya. History Santiago de Cuba province has been the site of many battles, both during the war for independence and the 1959 Cuban Revolution, where much of the guerrilla fighting took place in the mountainous province. Prior to 1976, Cuba was divided into six historical provinces. One of these was Oriente province, which was, prior to 1905, known as Santiago de Cuba province. The present day province comprises the south-central region of Oriente. Economy The province is rich in material resources such as iron and nickel. The economy, however, relies mostly on agriculture, with large plantations growing bananas, cacao, and coffee dotting the landscape. Industry is growing around the capital, as is tourism.

Epithet
An epithet (, ), also byname, is a descriptive term (word or phrase) known for accompanying or occurring in place of a name and having entered common usage. It has various shades of meaning when applied to seemingly real or fictitious people, divinities, objects, and binomial nomenclature. It can also be a descriptive title: for example, Pallas Athena, Phoebus Apollo, Alfred the Great, Suleiman the Magnificent, and Władysław I the Elbow-high. Many English monarchs have traditional epithets: some of the best known are Edward the Confessor, William the Conqueror, Richard the Lionheart, Æthelred the Unready, John Lackland and Bloody Mary. The word ''epithet'' can also refer to an abusive, defamatory, or derogatory phrase. This use as a euphemism is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler complained that "epithet is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes at ...
