Leucospora Multifida
''Leucospora multifida'', known variously as Obi-Wan conobea, narrow-leaved paleseed, cliff conobea, cut-leaved conobea, or much-cleft conobea, is an annual herb in the plantain family, Plantaginaceae, and the only species in the North American genus ''Leucospora''. Taxonomy and naming The genus ''Leucospora'', from the Greek for "white-seeded", was named in 1834 by English botanist Thomas Nuttall. Its sole species (), now known as ''Leucospora multifida'', was first described in 1803 by French botanist André Michaux as ''Capraria multifida''. The epithet ''multifida'' is Greek for "cleft many times", in reference to the shape of its leaves. It has since been placed in several different genera, including ''Leucospora'', '' Stemodia'', ''Sutera'', and '' Conobea'', the latter from which several of its vernacular names originate. While one of its names, Obi-Wan conobea, a reference to the Star Wars character Obi-Wan Kenobi, is sometimes considered purely a joke snuck into the ...

Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Rams ...

Plantaginaceae Genera
Plantaginaceae, the plantain family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain." In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: ''Bougueria'', ''Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, ''Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the International Code of B ...

Marl
Marl is an earthy material rich in carbonate minerals, clays, and silt. When hardened into rock, this becomes marlstone. It is formed in marine or freshwater environments, often through the activities of algae. Marl makes up the lower part of the cliffs of Dover, and the Channel Tunnel follows these marl layers between France and the United Kingdom. Marl is also a common sediment in post-glacial lakes, such as the marl ponds of the northeastern United States. Marl has been used as a soil conditioner and neutralizing agent for acid soil and in the manufacture of cement. Description Marl or marlstone is a carbonate-rich mud or mudstone which contains variable amounts of clays and silt. The term was originally loosely applied to a variety of materials, most of which occur as loose, earthy deposits consisting chiefly of an intimate mixture of clay and calcium carbonate, formed under freshwater conditions. These typically contain 35–65% clay and 65–35% carbonate. The te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Facultative Wetland
Wetland indicator status denotes the probability of individual species of vascular plants occurring in freshwater, brackish and saltwater wetlands in the United States. The wetland status of 7,000 plants is determined upon information contained in a list compiled in the National Wetland Inventory undertaken by the U.S. Fish and Wildlife Service and developed in cooperation with a federal inter-agency review panel (Reed, 1988). The National List was compiled in 1988 with subsequent revisions in 1996 and 1998. The wetland indicator status of a species is based upon the individual species occurrence in wetlands in 13 separate regions within the United States. In some instances the specified regions contain all or part of different floristic provinces and the tension zones which occur between them. While many Obligate Wetland (OBL) species do occur in permanently or semi-permanently flooded wetlands, there are also a number of obligates that occur in temporary or seasonally flooded ...

Adventive
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and neophyta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

André Michaux
André Michaux, also styled Andrew Michaud, (8 March 174611 October 1802) was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include ''Histoire des chênes de l'Amérique'' (1801; "The Oaks of North America") and ''Flora Boreali-Americana'' (1803; "The Flora of North America") which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist. Biography Michaux was born in Satory, part of Versailles, Yvelines, where his father managed farmland on the king's estate. Michaux was trained in the agricultural sciences in anticipation of his one-day assuming his father's duties, and received a basic classical 18th century education, including Latin and some Greek, until h ...
