Charles Leo Hitchcock
Charles Leo Hitchcock (April 23, 1902 – February 3, 1986) was an American botanist. He discovered 20 species of plants and his works have been cited thousands of times. He is also the primary co-author to the Flora of the Pacific Northwest, still the most up to date flora for three northwest U.S. States to date. A hall at the University of Washington is named in his honor, and he taught thousands of botanists over the course of his teaching career at the University of Washington. Selected works *''A Monographic Study of the Genus Lycium of the Western Hemisphere'' (1932) *''A Key to the Grasses of Montana Based upon Vegetative Characters'' (1936) *''The Tofieldia glutinosa Complex of Western North America'' (1944) *''A Revision of the North American Species of Lathyrus'' (1952) *''A Checklist of Vascular Plants of West-Central Washington'' (1969) *''Key to the Grasses of the Pacific Northwest Based upon Vegetative Characters'' (1969) *''Flora of the Pacific Northwest'' w ...

Bassett Maguire
Bassett Maguire (August 4, 1904 – February 6, 1991) was an American botanist, head curator of the New York Botanical Garden, and a leader of scientific expeditions to the Guyana Highlands in Brazil and Venezuela. Life Maguire was born in Gadsden, Alabama, on August 4, 1904. He obtained his doctorate from Cornell University in 1938. In 1931, he was appointed assistant professor of botany at Utah State University, where he started the Intermountain Herbarium and served as its principal collector and curator until 1942. He left his position in Utah when he got a job at the New York Botanical Garden in 1943. Maguire served at the New York Botanical Garden in many roles as Curator (1943-1958); Head Curator (1958-1961); Nathanial Lord Britton Distinguished Senior Curator (1961-1971); Assistant Director (1968-1969); Director of Botany (1969-1971, 1974-1975); Senior Scientist (1972-1974); and Senior Scientist Emeritus from 1975 until his death in 1991. While in Utah, Maguire started wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caryophyllaceae
Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 81 genera and about 2,625 known species. This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains. Some of the more commonly known members include pinks and carnations (''Dianthus''), and firepink and campions ('' Lychnis'' and ''Silene''). Many species are grown as ornamental plants, and some species are widespread weeds. Most species grow in the Mediterranean and bordering regions of Europe and Asia. The number of genera and species in the Southern Hemisphere is rather small, although the family does contain Antarctic pearlwort (''Colobanthus quitensis''), the world's southernmost dicot, which is one ...

Endemism
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring Mountains
The Spring Mountains are a mountain range of Southern Nevada in the United States, running generally northwest–southeast along the west side of Las Vegas and south to the border with California. Most land in the mountains is owned by the United States Forest Service and the Bureau of Land Management and managed as the Spring Mountains National Recreation Area within the Humboldt-Toiyabe National Forest and the Red Rock Canyon National Conservation Area. Geography The Spring Mountains range is named for the number of springs to be found, many of them in the recesses of Red Rock Canyon National Conservation Area, which is on the eastern side of the mountains. The Spring Mountains divide the Pahrump Valley and Amargosa River basins from the Las Vegas Valley watershed, which drains into the Colorado River watershed, by way of Las Vegas Wash into Lake Mead, thus the mountains define part of the boundary of the Great Basin. The Great Basin Divide, (one of the Great Basin region b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clark County, Nevada
Clark County is located in the U.S. state of Nevada. As of the 2020 census, the population was 2,265,461. Most of the county population resides in the Las Vegas Census County Divisions, which hold 1,771,945 people as of the 2010 Census, across . It is by far the most populous county in Nevada, and the 11th most populous county in the United States. It covers 7% of the state's land area but holds 74% of the state's population, making Nevada one of the most centralized states in the United States. History Las Vegas, the state's most populous city, has been the county seat since its establishment. The county was formed by the Nevada Legislature by splitting off a portion of Lincoln County, Nevada, Lincoln County on February 5, 1909, and was organized on July 1, 1909. The Las Vegas Valley (landform), Las Vegas Valley, a basin, includes Las Vegas and other major cities and communities such as North Las Vegas, Henderson, Nevada, Henderson, and the unincorporated community of Parad ...

Silene
''Silene'' is a genus of flowering plants in the family Caryophyllaceae. Containing nearly 900 species, it is the largest genus in the family. Common names include campion and catchfly. Many ''Silene'' species are widely distributed, particularly in the northern hemisphere. Scientific history Members of this genus have been the subject of research by preeminent plant ecologists, evolutionary biologists, and geneticists, including Charles Darwin, Gregor Mendel, Carl Correns, Herbert G. Baker, and Janis Antonovics. Many ''Silene'' species continue to be widely used to study systems, particularly in the fields of ecology and evolutionary biology.Bernasconi et al. 2009. Silene as a model system in ecology and evolution. Heredity. 103:5-14. PMI19367316/ref> The genus has been used as a model for understanding the genetics of sex determination for over a century. ''Silene'' species commonly contain a mixture of hermaphroditic and female (or male-sterile) individuals (gynodioecy), and ...
