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 the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Adoxaceae
Adoxaceae, commonly known as moschatel family, is a small family of flowering plants in the order Dipsacales, now consisting of five genera and about 150–200 species. They are characterised by opposite toothed leaves, small five- or, more rarely, four-petalled flowers in cymose inflorescences, and the fruit being a drupe. They are thus similar to many Cornaceae. In older classifications, this entire family was part of Caprifoliaceae, the honeysuckle family. ''Adoxa'' (moschatel) was the first plant to be moved to this new group. Much later, the genera '' Sambucus'' (elders) and '' Viburnum'' were added after careful morphological analysis and biochemical tests by the Angiosperm Phylogeny Group. An additional monotypic genus '' Sinadoxa'' has been added based on molecular comparison with ''Adoxa''. Recent sources, including the Angiosperm Phylogeny Website, treat this family as Viburnaceae Raf., ''nom. cons.'' ''Adoxa'' is a small perennial herbaceous plant, flowering ea ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Honduras
Honduras, officially the Republic of Honduras, is a country in Central America. It is bordered to the west by Guatemala, to the southwest by El Salvador, to the southeast by Nicaragua, to the south by the Pacific Ocean at the Gulf of Fonseca, and to the north by the Gulf of Honduras, a large inlet of the Caribbean Sea. Its Capital city, capital and largest city is Tegucigalpa. Honduras was home to several important Mesoamerican cultures, most notably the Maya civilization, Maya, before Spanish colonization of the Americas, Spanish colonization in the sixteenth century. The Spanish introduced Catholic Church, Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability, and remains one of the poorest countries in the Western Hemisphere. In 1960, the northern part o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viburnum
''Viburnum'' is a genus of about 150–175 species of flowering plants in the moschatel family, Adoxaceae. Its current classification is based on molecular phylogeny. It was previously included in the honeysuckle family Caprifoliaceae. The member species are evergreen or deciduous shrubs or (in a few cases) small trees native throughout the temperate Northern Hemisphere, with a few species extending into tropical montane regions in South America and southeast Asia. In Africa, the genus is confined to the Atlas Mountains. Name The generic name ''Viburnum'' originated in Latin, in which it referred to '' V. lantana''. Description The leaves are opposite, simple, and entire, with toothed or lobed margins. Cool temperate species are deciduous, while most of the warm temperate species are evergreen. Some species have densely hairy shoots and leaves covered in star-shaped hairs. The flowers are produced in corymbs 5–15 cm across. Each flower is white, cream or pink, sm ...
