Coreopsis Chippii
''Bidens chippii'' is a species of flowering plant in the family Asteraceae. It belongs to the genus ''Bidens''. The plant was at first named ''Coreopsis chippii'' after British botanist Thomas Ford Chipp (1886–1931)). Chipp found it on 11 February 1929 growing in scrub at an altitude of on top of Mount Kinyeti in the Imatong Mountains The Imatong Mountains (also Immatong, or rarely Matonge) are mainly located in Eastern Equatoria in southeastern South Sudan, and extend into the Northern Region of Uganda.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

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 ...

Bidens
''Bidens'' is a genus of flowering plants in the aster family, Asteraceae.''Bidens''. Flora of North America. The genus include roughly 230 species which are distributed worldwide.Knope, M.

Thomas Ford Chipp
Thomas Ford Chipp (1 January 1886 – 28 June 1931) was an English botanist who became Assistant Director of the Royal Botanic Gardens, Kew. He played an important role in development of the study of ecology in the British Empire. Early career Chipp was born in 1886, son of a constable in Gloucester who died when Thomas was five years old. Chipp was accepted by the Royal Masonic School, and then became a student gardener at Kew. He was admitted to University College, London, earning a degree in botany in 1909. He then obtained a job as conservator of forests in the Gold Coast colony. His reports from this period show enthusiasm for developing the colonial economy combined with interest in the local environment and people. Detailed reports on local estates covered topography, climate, ecology, commercial value and suggestions for improvements. The reports were written for the use of local landowners and were not published in scientific journals. A highly organized man, with gr ...

Mount Kinyeti
Mount Kinyeti is the highest peak in South Sudan. It is located in the Imatong Mountains in Ikwoto County of Eastern Equatoria, near the Ugandan border. Kinyeti has an elevation of above sea level. The group of high mountains that contain Kinyeti, extending to the border with Uganda, are sometimes called the Lomariti or Lolobai mountains. The lower parts of the mountain were covered with lush forest. These are the most northern forests of the East African montane forest ecoregion. The summit is rocky, with montane grassland and scattered, low ericaceous scrubs, low subshrub and herbs in rock crevices. One of the first Europeans to visit the mountain was the botanist Thomas Ford Chipp Thomas Ford Chipp (1 January 1886 – 28 June 1931) was an English botanist who became Assistant Director of the Royal Botanic Gardens, Kew.

Imatong Mountains
The Imatong Mountains (also Immatong, or rarely Matonge) are mainly located in Eastern Equatoria in southeastern South Sudan, and extend into the Northern Region of Uganda. Mount Kinyeti is the highest mountain of the range at , and the highest point of South Sudan. The range has an equatorial climate and had dense montane forests supporting diverse wildlife. Since the mid-20th century the rich ecology has increasingly been severely degraded by native forest clearance and subsistence farming, causing extensive erosion of the slopes. Geography The Imatong Mountains massif lies mainly within Torit County (western part) and Ikotos County (eastern part) of Imatong State. It is located some southeast of Juba and south of the main road from Torit to the Kenyan border town of Lokichoggio. The mountain range rises steeply from the surrounding plains, which slope gradually down from about on the South Sudan-Uganda border in the south to at Torit in the north. These plains are c ...

Endemic Flora Of South Sudan
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
