Lorenzochloa
''Lorenzochloa'' is a monotypic genus of perennial plants in the grass family. The only known species is ''Lorenzochloa erectifolia'' They are native to South America. It was formerly placed in the Ortachne genus, as ''Ortachne erectifolia'', until phylogenetic analysis. They are found in Colombia, Costa Rica, Ecuador, Peru and Venezuela. The genus name of ''Lorenzochloa'' is in honour of Lorenzo Raimundo Parodi (1895–1966), who was an Argentinian botanist and agricultural engineer, professor of botany in Buenos Aires and La Plata with a focus on South American grasses. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius. Not every polyg ... in Bol. Soc. Argent. Bot. vol.11 on page 239 in 1969.

John Raymond Reeder
John Raymond Reeder (July 29, 1914 – February 8, 2009) was an American agrostologist who was active in identifying the grasses of New Guinea, Wyoming, and Arizona. Biography Reeder was born on a farm in Charlotte, Michigan on July 29, 1914. He went on to attend Oregon State University and met Charlotte Olive Goodding, whom he married in 1941. Reeder joined the military upon the involvement of America in World War II. He was stationed in a malaria unit in New Guinea. While on duty, he collected grasses for curation back in America. Upon his return from the war, Reeder was accepted into a Ph.D. program at Harvard University. He took classes while also working at the Arnold Arboretum, and eventually earned his doctorate. In 1947, he accepted a position at Yale University in the forestry department. He taught courses on dendrology, agrostology, and plant taxonomy. He also served as Curator of the Herbarium at the Peabody Museum of Natural History. In 1968, Reeder and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charlotte Goodding Reeder
Charlotte Goodding Reeder (born Charlotte Olive Goodding; July 26, 1916 – October 23, 2009) was an American agrostologist who was active in identifying the flora of Arizona. The abbreviation C.O.Goodd. has also been used. Biography Reeder was born on July 26, 1916 in Flagstaff, Arizona. She was the daughter of accomplished botanist Leslie Newton Goodding. Picking up from her father, she began to help him identify species in Arizona. She attended the University of Wyoming, earning her M.A. in 1939 for her thesis on '' Muhlenbergia''.

Monotypic
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. ...

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Lorenzo Raimundo Parodi
Lorenzo Raimundo Parodi (born 23 January 1895 in Pergamino, Buenos Aires Province - died 21 April 1966 in Buenos Aires) was an Argentinian botanist and agronomist. Parodi studied at the University of Buenos Aires Faculty of Agronomy under Lucien Leon Hauman and in 1926 took Hauman's place as professor of botany. Several plant genera, have been named in his honour; in 1929, '' Parodiodoxa'', a genus of flowering plants from Argentina, belonging to the family Brassicaceae, then in 1941, ''Parodianthus'', a genus of flowering plants from Argentina belonging to the family Verbenaceae. Followed by in 1969, ''Parodiodendron'', a genus under the family Picrodendraceae, and lastly in 2008, ''Parodiophyllochloa'' is a genus of Latin American plants in the grass family Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses.

Buenos Aires
Buenos Aires ( or ; ), officially the Autonomous City of Buenos Aires ( es, link=no, Ciudad Autónoma de Buenos Aires), is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia, Italy. Buenos Aires is classified as an alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking. The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include t ...

La Plata
La Plata () is the capital city of Buenos Aires Province, Argentina. According to the , it has a population of 654,324 and its metropolitan area, the Greater La Plata, has 787,294 inhabitants. It is located 9 kilometers (6 miles) inland from the southern shore of the Río de la Plata estuary. La Plata was planned and developed to serve as the provincial capital after the city of Buenos Aires was federalized in 1880. It was officially founded by Governor Dardo Rocha on 19 November 1882. Its construction is fully documented in photographs by Tomás Bradley Sutton. La Plata was briefly known as ''Ciudad Eva Perón'' (Eva Perón City) between 1952 and 1955. The city is home to two important first division football teams: Estudiantes de La Plata and Gimnasia y Esgrima La Plata. History and description After La Plata was designated the provincial capital, Rocha was placed in charge of creating the city. He hired urban planner Pedro Benoit, who designed a city layout based on a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pooideae
The Pooideae are the largest subfamily of the grass family Poaceae, with about 4,000 species in 15 tribes and roughly 200 genera. They include some major cereals such as wheat, barley, oat, rye and many lawn and pasture grasses. They are often referred to as cool-season grasses, because they are distributed in temperate climates. All of them use the C3 photosynthetic pathway. The Pooideae are the sister group of the bamboos within the BOP clade, and are themselves subdivided into 15 tribes. Phylogeny Relationships of tribes in the Pooideae according to a 2017 phylogenetic In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups o ... classification, also showing the bamboos as sister group: References External links Poaceae subfamilies {{Poaceae-stub ...
