Stenanthium Densum
''Stenanthium densum'' is a poisonous but spectacular monocot wildflower native to pine barrens of the eastern United States. It is known variously as Osceola's plume, crowpoison, or black snakeroot. '' Stenanthium leimanthoides'' is either treated as a synonym of this species or as a separate species. It is native to the southernmost Gulf Coast, from eastern Louisiana east, down through most of Florida, and to the easternmost Atlantic Coast north to Rhode Island, seldom far from the coast. Within the family Melanthiaceae, it is placed in the tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in substantial rearrangement of the species in this tribe, many being moved to different genera. ''S.'' ''densum'' was previously placed in ''Zigadenus ''Zigadenus'' is a genus of flowering plants now containing only one species, ''Zigadenus glaberrimus'', the sandbog death camas, found in the southeastern United States from Mississippi to Virginia. ...

Louis Auguste Joseph Desrousseaux
Louis Auguste Joseph Desrousseaux (27 July 1753 – 20 January 1838) was a French botanist and pteridologist. He was a contributor to the "Encyclopedia Botanique" of Lamarck, from 1783 to 1796. Desrousseaux produced many works on new plant species, creating 414 new records. In 1828, botanist Augustin Pyramus de Candolle (DC.) published '' Rousseauxia'', a genus of flowering plants from Madagascar, belonging to the family Melastomataceae Melastomataceae is a family of dicotyledonous flowering plants found mostly in the tropics (two-thirds of the genera are from the New World tropics) comprising c. 175 genera and c. 5115 known species.

Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site at Kew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zigadenus
''Zigadenus'' is a genus of flowering plants now containing only one species, ''Zigadenus glaberrimus'', the sandbog death camas, found in the southeastern United States from Mississippi to Virginia. Around 20 species were formerly included in the genus, but have now been moved to other genera. Description ''Zigadenus glaberrimus'' generally grows to a height of . A total of 30–70 flowers are borne in panicles. Each white to cream colored flower is bell-shaped, across. The tepals of the flower remain attached to the fruit capsule when it forms. The cone shaped seed capsules are long by across. ''Zigadenus glaberrimus'' flowers from mid July to September. It is found growing in pine bogs, savannas and sandy pinelands in the US states of Alabama, Florida, Georgia, Mississippi, Virginia, North Carolina and South Carolina. Systematics The genus is a member of the family Melanthiaceae, tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in numb ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Melanthieae
Melanthieae is a tribe of flowering plants within the family Melanthiaceae. Molecular phylogenetic studies in the 21st century have resulted in a large-scale reassignment of many of its species to different genera; in particular the genus ''Zigadenus'' (deathcamases) has been restricted to a single species, ''Zigadenus glaberrimus''. Plants contain alkaloids, making them unpalatable to grazing animals; many are very poisonous to both animals and humans. Description Like the family as a whole, members of the tribe are "lilioid monocots", i.e. their flowers superficially resemble those of the genus ''Lilium'', with six tepals not differentiated into sepals and petals. As with other lilioid monocots, they were previously included in a broadly defined family Liliaceae. They are found mainly in woodland or alpine habitats in the temperate regions of the Northern Hemisphere (North America, Central America, and Asia), with one species found in South America. They are perennials, growing ... [...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 ...

Stenanthium Leimanthoides
''Stenanthium leimanthoides'' is a poisonous monocot wildflower native to acid montane areas of the eastern United States. It is either treated as a separate species to ''Stenanthium densum'' or as a synonym of that species. A common name is pine barren deathcamas. Within the family Melanthiaceae, it is placed in the tribe Melanthieae. Molecular phylogenetic studies in the 21st century have resulted in substantial rearrangement of the species in this tribe, many being moved to different genera. ''S.'' ''leimanthoides'' was previously placed in ''Zigadenus'' as ''Z. leimanthoides'', and will be found under this name in older sources. It is native to the southernmost United States, more inland than ''S. densum'', largely in the Appalachian Mountains The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gulf Coast
The Gulf Coast of the United States, also known as the Gulf South, is the coastline along the Southern United States where they meet the Gulf of Mexico. The coastal states that have a shoreline on the Gulf of Mexico are Texas, Louisiana, Mississippi, Alabama, and Florida, and these are known as the ''Gulf States''. The economy of the Gulf Coast area is dominated by industries related to energy, petrochemicals, fishing, aerospace, agriculture, and tourism. The large cities of the region are (from west to east) Brownsville, Corpus Christi, Houston, Galveston, Beaumont, Lake Charles, Lafayette, Baton Rouge, New Orleans, Gulfport, Biloxi, Mobile, Pensacola, Navarre, St. Petersburg, and Tampa. All are the centers or major cities of their respective metropolitan areas and many of which contain large ports. Geography The Gulf Coast is made of many inlets, bays, and lagoons.
