Pitcairnia Feliciana
''Pitcairnia feliciana'' is a plant endemic to central Guinea in West Africa and is the only species of bromeliad not native to the Americas. It can be found growing on sandstone outcrops (inselbergs) of the Fouta Djallon highlands in Middle Guinea. Its specific epithet ''feliciana'' commemorates (1907–2008), the French botanist who first collected it. In 1937, he discovered the plants growing on the steep rocks of Mount Gangan, near Kindia in the former French Guinea. The speciation occurred around 10 million years ago, therefore its distribution cannot be due to continental drift Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of pla ..., the Americas having separated from Africa much earlier. The species probably originates from seeds dispersed by migrating birds. It has bright ora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann August Theodor Harms
Hermann August Theodor Harms (16 July 1870 – 27 November 1942) was a German taxonomist and botanist. Harms was born in Berlin. He worked as a botanist at the Botanical Museum in Berlin. He was a member of the Prussian Academy of Sciences. He died in Berlin, aged 52. He was longtime editor of Adolf Engler's "''Das Pflanzenreich''", and was the author of several chapters on various plant families in Engler and Prantl's "''Die Natürlichen Pflanzenfamilien''", including the chapters on Bromeliaceae (1930) and Nepenthaceae (1936). In the latter he revised the pitcher plant genus ''Nepenthes'', dividing it into three subgenera: ''Anurosperma'', ''Eunepenthes'' and ''Mesonepenthes'' (see Taxonomy of ''Nepenthes''). Furthermore, he was interested in the genus ''Passiflora''. The plant genera ''Harmsia'' (Schum.), '' Harmsiella'' ( Briq.), '' Harmsiodoxa'' (in the Brassicaceae family) and ''Harmsiopanax'' (in the ''Araliaceae'' family) commemorate his name.

French Guinea
French Guinea (french: Guinée française) was a French colonial possession in West Africa. Its borders, while changed over time, were in 1958 those of the current independent nation of Guinea. French Guinea was established by France in 1891, within the same borders as its previous colony known as Rivières du Sud (1882–1891). Prior to 1882, the coastal portions of French Guinea were part of the French colony of Senegal. In 1891, Rivières du Sud was placed under the colonial lieutenant governor at Dakar, who had authority over the French coastal regions east to Porto-Novo (modern Benin). In 1894 Rivières du Sud, Cote d'Ivoire and Dahomey were separated into 'independent' colonies, with Rivières du Sud being renamed as the Colony of French Guinea. In 1895, French Guinea was made one of several dependent colonies and its Governor became one of several Lieutenant Governors who reported to a Governor-General in Dakar. In 1904, this federation of colonies was formalised as Fre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Guinea
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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pitcairnia
''Pitcairnia'' is a genus of plants in the Family (biology), family Bromeliaceae, subfamily Pitcairnioideae. It was named for William Pitcairn, Scottish physician and gardener (1711–1791). The genus ''Pitcairnia'' ranks as the second most prolific of the bromeliad family (after ''Tillandsia).'' They are most abundant in Colombia, Peru and Brazil, but can also be found in areas from Cuba and Mexico south to Argentina. One species, ''Pitcairnia feliciana'', is found in tropical West Africa and is the only member of the family Bromeliaceae not native to the Americas. Almost all ''Pitcairnias'' are Terrestrial plant, terrestrial or wiktionary:saxicolous, saxicolous, and prefer moist areas. However, many are found growing epiphyte, epiphytically in trees. Taxonomy ''Pitcairnia'' was established as a genus by Charles Louis L'Héritier de Brutelle in 1788. In 1870, ''Pepinia'' was established as a genus by Adolphe-Théodore Brongniart in a publication by Édouard André. ''Pepinia'' ...

Bird Pollination
Ornithophily or bird pollination is the pollination of flowering plants by birds. This sometimes (but not always) coevolutionary association is derived from insect pollination (entomophily) and is particularly well developed in some parts of the world, especially in the tropics, Southern Africa, and on some island chains. The association involves several distinctive plant adaptations forming a "pollination syndrome". The plants typically have colourful, often red, flowers with long tubular structures holding ample nectar and orientations of the stamen and stigma that ensure contact with the pollinator. Birds involved in ornithophily tend to be specialist nectarivores with brushy tongues and long bills, that are either capable of hovering flight or light enough to perch on the flower structures. Plant adaptations Plant adaptations for ornithophily can be grouped primarily into those that attract and facilitate pollen transfer by birds, and those that exclude other groups, primaril ...

A Journal Of Systematic And Evolutionary Botany
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Continental Drift
Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The idea of continental drift has been subsumed into the science of plate tectonics, which studies the movement of the continents as they ride on plates of the Earth's lithosphere. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. A pioneer of the modern view of mobilism was the Austrian geologist Otto Ampferer.Helmut W. Flügel: Die virtuelle Welt des Otto Ampferer und die Realität seiner Zeit'. In: Geo. Alp., Vol. 1, 2004. The concept was independently and more fully developed by Alfred Wegener in 1912, but the hypothesis was rejected by many for lack of any motive mechanism. The English geologist Arthur Holmes later proposed mantle convection for that mechanism. History Early history Abraham Ortelius , Theodor Christoph Lilienthal (1756), A ...

Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments of speciation, laboratory experiments. Whether genetic drift is a minor or major contributor to speciation is the subject of much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
