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 at an altitude of 1000 m on November 18, 1983. The specific epithet An epithet (, ), also a byname, is a descriptive term (word or phrase) commonly accompanying or occurring in place of the name of a real or fictitious person, place, or thing.

Cyatheales
The order Cyatheales, which includes most tree ferns, is a Taxonomy (biology), taxonomic order of the fern class, Polypodiopsida. No clear morphology (biology), morphological features characterize all of the Cyatheales, but DNA sequence data indicate the order is monophyly, 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 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 bec ...

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 ...

Interspecific Hybrid
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate 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 hybridization, which include genetic and morpholog ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism 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 and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

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 (wine), 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 diff ... [...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, Cuba, Contramaestre, San Luis, Santiago de Cuba, 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 warfare, guerrilla fighting took place in the forested and mountainous province. Prior to 1976, Cuba was divided into six Provinces of Cuba#History, historical provinces. One of these was Oriente Province, Oriente province, which was, prior to 1905, known as Santiago de Cuba province. The present day province comprises the south-central region of Oriente.

Epithet
An epithet (, ), also a byname, is a descriptive term (word or phrase) commonly accompanying or occurring in place of the name of a real or fictitious person, place, or thing. It is usually literally descriptive, as in Alfred the Great, Suleiman the Magnificent, Richard the Lionheart, and Ladislaus the Short, or allusive, as in Edward the Confessor, William the Conqueror, Æthelred the Unready, John Lackland, Mehmed the Conqueror and Bloody Mary. The word ''epithet'' also may refer to an abusive, defamatory, or derogatory word or phrase. This use is criticized by Martin Manser and other proponents of linguistic prescription. H. W. Fowler noted in 1926 that "''epithet'' is suffering a vulgarization that is giving it an abusive imputation." Linguistics Epithets are sometimes attached to a person's name or appear in place of their name, as what might be described as a glorified nickname or sobriquet, and for this reason some linguists have argued that they should be c ...
