Cyrus Longworth Lundell
Cyrus Longworth Lundell (November 5, 1907 – March 28, 1994) was an American botanist. Education Lundell did his undergraduate studies at Columbia University and Southern Methodist University. He completed his BA at the later in 1932. He then entered New York University's graduate school of business administration, but seems not to have completed course work there. He received an M.A. from the University of Michigan in 1934 and a Ph.D. from the same institution in 1936. It appears based on his later professorship that his Ph.D. was in botany. Early achievement At the age of 21, in 1928, Lundell was a sophomore at Southern Methodist University (SMU). He was appointed assistant physiologist at the Tropical Plant Research Foundation in Washington, D.C. He was to assist in British Honduras, with experiments on the sapodilla tree (''Achras zapota''), which yields chicle, for the U.S. chewing gum industry. Chicle Chicle is the natural gum from trees of the genus ''Manilkara'', tropic ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

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 ...

Hamamelidaceae
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. An earlier system, the Cronquist system, recognized Hamamelidaceae in the Hamamelidales order. Description The Hamamelidaceae are distinguishable from other families in the Saxifragales due to the range of floral characteristics that are generally uniform though all genera. Uniform characteristics include stipules borne on stems with leaves often 2-ranked. Genera usually have a two carpel gynoecium, although some species show variation. Other characteristics include a multicellular stigma, with shallow papillae or ridges. Anthers Anther structure and the modes of opening are considered to be one of the most important features in the systematics and evolution of hamamelids. The anthers in Hamamelids are on average shorter than in other families in t ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eizi Matuda
(1894–1978) was a Mexican botanist of Japanese origin. In scholarly works his name is generally romanised Romanization or romanisation, in linguistics, is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and ... as "Eizi Matuda" following the "Kunrei" system. Biography Matuda and his wife, Miduho Kaneko de Matuda, were naturalized Mexican citizens and had five Mexico-born children. Legacy In 1956, a species of cactus native to Mexico was named in his honor, the '' Mammillaria matudae''. The genus '' Matudina'' in the sunflower family is also named in his honor. Two species and one subspecies of reptiles are named in his honor: '' Abronia matudai'' (Matuda's arboreal alligator lizard), '' Anolis matudai'' (Matuda's anole), and '' Pseudelaphe flavirufa matudai'' (Matuda's ratsnake).Beolens, Bo; Watkins, Michael; Grayson, Michael ...

Japanese Mexicans
Japanese Mexicans are Mexicans of Japanese ancestry. As of 2019, there are an estimated 76,000 people who are Japanese or of Japanese descent in Mexico. Japanese immigration to Mexico began in the late 19th century, to found coffee growing plantations in the state of Chiapas. Although this initiative failed, it was followed by greater immigration from 1900 to the beginning of World War II, although it never reached the levels of Japanese immigration to countries like the United States, or Brazil. Immigration halted during World War II and many Japanese nationals and even some naturalized Mexicans citizens of Japanese origin were forced to relocate from communities in Baja California, Sinaloa and Chiapas to Mexico City and other areas in the interior until the war was over. After the war, immigration began again, mostly due to Japanese companies investing in Mexico and sending over skilled employees. History Early history In the years 1613 through 1620, several diplomatic missions ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Saxifragales Genera
The Saxifragales (saxifrages) are an order of flowering plants (Angiosperms). They are an extremely diverse group of plants which include trees, shrubs, perennial herbs, succulent and aquatic plants. The degree of diversity in terms of vegetative and floral features makes it difficult to define common features that unify the order. In the Angiosperm Phylogeny Group classification system, the Saxifragales are placed within the major division of flowering plants referred to as eudicots, specifically the core eudicots. This subgroup consists of the Dilleniaceae, superasterids and superrosids. The superrosids in turn have two components, rosids and Saxifragales. The Saxifragales order has undergone considerable revision since its original classification based purely on plant characteristics. The modern classification is based on genetic studies using molecular phylogenetics. There is an extensive fossil record from the Turonian-Campanian (late Cretaceous) time, about 90 mill ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...
