Botrychium Lanceolatum
''Botrychium lanceolatum'', known as lanceleaf moonwort, is a species of plant belonging to the family Ophioglossaceae. Its native range is subarctic and temperate Northern Hemisphere including Greenland. Taxonomy ''Botrychium lanceolatum'' was first described as ''Osmunda lanceolata'' by Samuel Gottlieb Gmelin Samuel George Gottlieb Gmelin (4 July 1744 – 27 July 1774) was a German physician, botanist, and explorer. Background Gmelin was born at Tübingen as part of a well-known family of naturalists. His father was Johann Conrad Gmelin, an apotheca ... in 1768.

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 ...

Ophioglossaceae
Ophioglossaceae, from Ancient Greek ὄφις (''óphis''), meaning "snake", and γλῶσσα (''glôssa''), meaning "tongue", also known as the adder's-tongue family, is a small family of ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), it is the only family in the order Ophioglossales, which together with the Psilotales is placed in the subclass Ophioglossidae. The Ophioglossidae are one of the groups traditionally known as eusporangiate ferns. Members of the family differ from other ferns in a number of ways. Many have only a single fleshy leaf at a time. Their gametophytes are subterranean and rely on fungi for energy. Description Members of Ophioglossaceae are usually terrestrial (excepting a few epiphytic species of '' Ophioglossum'') and occur in both temperate and tropical areas. They differ from the other ferns in several respects: * Many species only send up one frond or leaf-blade per year, producing only a single leaf at a time. The leaves ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel Gottlieb Gmelin
Samuel George Gottlieb Gmelin (4 July 1744 – 27 July 1774) was a German physician, botanist, and explorer. Background Gmelin was born at Tübingen as part of a well-known family of naturalists. His father was Johann Conrad Gmelin, an apothecary and surgeon. His uncle was Johann Georg Gmelin, who was also uncle to Johann Friedrich Gmelin (the naturalist publisher of the ''Systema Naturae'' of Carolus Linnaeus). Samuel earned his medical degree in 1763 from the University of Leiden at the young age of 18. While living in the Dutch Republic, Gmelin developed a keen interest in marine algae. In 1766 he was appointed professor of botany at St Petersburg. In the following year he was sent on an expedition to study the natural history of the Russian Empire. He explored the rivers Don and Volga, and the western and eastern coasts of the Caspian Sea. Whilst travelling in the Caucasus he was taken hostage by Usmey Khan of Khaïtakes and died of ill treatment in captivity in Akhmedkent ...

Botrychium
''Botrychium'' is a genus of ferns, seedless vascular plants in the family Ophioglossaceae. ''Botrychium'' species are known as moonworts. They are small, with fleshy roots, and reproduce by spores shed into the air. One part of the leaf, the trophophore, is sterile and fernlike; the other, the sporophore, is fertile and carries the clusters of sporangia or spore cases. Some species only occasionally emerge above ground and gain most of their nourishment from an association with mycorrhizal fungi. The circumscription of ''Botrychium'' is disputed between different authors; some botanists include the genera '' Botrypus'' and '' Sceptridium'' within ''Botrychium'', while others treat them as distinct. The latter treatment is provisionally followed here.
