Chonocentrum
''Chonocentrum'' is a genus of the family Phyllanthaceae described as a genus in 1922. It contains only known species, ''Chonocentrum cyathophorum'', native to the State of Amazonas in northwestern Brazil. The genus is still not well understood; W. John Hayden has observed that the plant seems have been collected just once, in upper Rio Negro of Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America.

Ferdinand Albin Pax
Ferdinand Albin Pax (26 July 1858 – 1 March 1942) was a German botanist specializing in spermatophytes. A collaborator of Adolf Engler, he wrote several monographs and described several species of plants and animals from Silesia and the Carpathians. He was a professor at Wrocław University from 1893. His son Ferdinand Albert Pax (1885–1964) was a noted zoologist. Life and work Pax was born on 26 July 1858 in Dvůr Králové nad Labem, in what was then known as Bohemia, to Carl Ferdinand, a mine superintendent in Schatzlar, and Elisabeth Haas (died 1861). He graduated from the Kamienna Góra gymnasium and joined the University of Wrocław. He received a PhD in 1882 studying under Heinrich Göppert and moved to Kiel and habilitated in 1886 for studies on the Cyperaceae. He served as an assistant at the Botanical Garden and moved to Berlin in 1889 where he worked with Adolf Engler. In 1893 he became the chair of botany at Wrocław. He became a professor of botany and zoolog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Monotypic Malpighiales 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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Rio Negro (Amazon)
The Rio Negro ( pt, Rio Negro, br ; es, Río Negro} "''Black River''"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. Geography Upper course The source of the Rio Negro lies in Colombia, in the Department of Guainía where the river is known as the ''Guainía River''. The young river generally flows in an east-northeasterly direction through the Puinawai National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén. After roughly 400 km the river starts forming the border between Colombia's Department of Guainía and Venezuela's Amazonas State. After passing the Colombian community of Tonina and Macanal the river turns Southwest. Maroa is the first Venezuelan town the river passes. 1 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Johannes Müller Argoviensis
Johann Müller (9 May 1828 - 28 January 1896) was a Swiss botanist who was a specialist in lichens. He published under the name Johannes Müller Argoviensis to distinguish himself from other naturalists with similar names. Biography Müller was born into a farming family on 9 May 1828 in Teufenthal, Switzerland. He received his education at the Reinach gymnasium and then entered the Aargau industrial school, where he was passionate about botany and mathematics. Encouraged by Hans Schinz he built a herbarium of the flora of Aargau. In 1850 and 1851 he studied in Geneva and came into contact with prominent botanists Edmond Boissier and Alphonse Pyrame de Candolle (who offered him the vacant post of curator at his herbarium). In the spring of 1851 he collected in southern France with Jean Étienne Duby. The herbarium specimens from this trip were later sent to several herbaria in Europe. The following year, Müller travelled with Boissier to collect plants in the Alps of Savoy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiosperms
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils are in the ...
