Bignoniaceae
Bignoniaceae () is a Family (biology), family of flowering plants in the Order (biology), order Lamiales commonly known as the bignonias or trumpet vines.Vernon H. Heywood, Richard K. Brummitt, Ole Seberg, and Alastair Culham. ''Flowering Plant Families of the World''. Firefly Books: Ontario, Canada. (2007). . It is not known to which of the other families in the order it is most closely related.Peter F. Stevens (2001 onwards). "Bignoniaceae" At: Angiosperm Phylogeny Website. At: Botanical Databases At: Missouri Botanical Garden Website. (see ''External links'' below) Nearly all of the Bignoniaceae are woody plants, but a few are subwoody, either as vines or subshrubs. A few more are herbaceous plants of high-elevation Montane ecology, montane habitats, in three exclusively herbaceous genera: ''Tourrettia'', ''Argylia'', and ''Incarvillea''. The family includes many lianas, climbing by tendrils, by twining, or rarely, by aerial roots. The largest Tribe (biology), tribe in the fam ...

Carl Friedrich Philipp Von Martius
Carl Friedrich Philipp (Karl Friedrich Philipp) von Martius (17 April 1794 – 13 December 1868) was a German botany, botanist and explorer. Between 1817 and 1820, he travelled 10,000 km through Brazil while collecting botanical specimens. His most important work was a comprehensive flora of Brazil, ''Flora Brasiliensis'', which he initiated in 1840 and was completed posthumously in 1906. Life Martius was born at Erlangen, the son of Prof Ernst Wilhelm Martius, court apothecary. He graduated PhD from University of Erlangen–Nuremberg, Erlangen University in 1814, publishing as his thesis a critical catalogue of plants in the university's botanical garden. After that he continued to devote himself to botanical study, and in 1817 he and Johann Baptist von Spix were sent to Brazil by Maximilian I Joseph of Bavaria, Maximilian I Joseph, the king of Bavaria. They travelled from Rio de Janeiro through several of the southern and eastern provinces of Brazil and travelled up the Amazon ...

Carl Meissner
Carl Daniel Friedrich Meissner (1 November 1800 – 2 May 1874) was a Swiss botanist. Biography Born in Bern, Switzerland on 1 November 1800, he was christened Meisner but later changed the spelling of his name to Meissner. For most of his 40-year career he was Professor of Botany at University of Basel. He made important contributions to the botanical literature, including the publication of the comprehensive work ''Plantarum Vascularum Genera'', and publications of monographs on the families Polygonaceae (especially the genus ''Polygonum''), Lauraceae, Proteaceae, Thymelaeaceae and Hernandiaceae. His contributions to the description of the Australian flora were prolific; he described hundreds of species of Australian Proteaceae, and many Australian species from other families, especially Fabaceae, Mimosaceae and Myrtaceae. His health deteriorated after 1866, and he was less active. He died in Basel Basel ( ; ), also known as Basle ( ), ; ; ; . is a city in northwes ...

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 ...

Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported cle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Forest
Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the Tropic of Cancer, tropics of Cancer and Tropic of Capricorn, Capricorn, but possibly affected by other factors such as prevailing winds. Some tropical forest types are difficult to categorize. While forests in temperate climate, temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. There is no single scheme that defines what a forest is, in tropical regions or elsewhere.Anatoly Shvidenko, Charles Victor Barber, Reidar Persson et al. 2005 "Millennium Ecosystem Assessment." Ecosystems and human wellbeing: a framework for assessment Washington, DC: Island Press Because of these difficulties, information on the extent of tropical forests varies between sources. However, tropical forests are extensive, making up just under half the world's forests. The tropical domain has the largest proportion of ...

Monotypic Lamiales Genera
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 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 system. ...
