Japanobotrychum
''Japanobotrychum'' is a genus of ferns in the family Ophioglossaceae with the sole species ''Japanobotrychum lanuginosum''. The genus is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I) (under the name "''Japanobotrychium''"), but not by some other sources. Taxonomy The genus ''Japanobotrychum'' was first described in 1931 by the Japanese botanist Genkei Masamune, with the only species being ''Japanobotrychum arisanense''. This is now considered to be a synonym of ''Botrychium lanuginosum'' Wall. ex Hook. & Grev., first described in 1828, so the epithet ''lanuginosum'' has priority over ''arisanense''. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) accepts the genus (with the spelling "''Japanobotrychium''"), with one species, as did the ''Checklist of Ferns and Lycophytes of the World'' , whereas ''Plants of the World Online'' subsumed the genus into ''Botrychium''. Distribution ''Japanobotrychum lanuginosum'' is widely distributed, ...

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
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Fern
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaf, leaves called megaphylls that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled Fiddlehead fern, fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae (plant), Polypodiidae) and eusporangiate ferns, the latter group including horsetails, Psilotaceae, whisk ferns, marattioid ferns, and ophioglossoid ferns. The fern crown group, consisting of the leptosporangiates and ...

Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group (PPG) is an informal international group of systematic botanists who collaborate to establish on the classification of pteridophytes ( lycophytes and ferns) that reflects knowledge about plant relationships discovered through phylogenetic studies. In 2016, the group published a classification for extant pteridophytes, termed "PPG I". The paper had 94 authors (26 principal and 68 additional). The classification was presented as a consensus classification supported by the community of fern taxonomists. Alternative classifications of ferns exist and are preferred by some. PPG I A first classification, PPG I, was produced in 2016, covering only extant (living) pteridophytes. The classification was rank-based, using the ranks of class, subclass, order, suborder, family, subfamily and genus. Phylogeny The classification was based on a consensus phylogeny, shown below to the level of order. The very large order Polypodiales was divided into two subord ...

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized Author citation (botany), author abbreviations. These were initially based on Authors of Plant Names, Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium (Australian Plant Name Index, APNI). The IPNI database is a collection of the names registered by the three cooperating ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

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. Phylogeny Phylogeny of ''Botrychium'' Unassigned species: * (thin-leaved moonwort) * '' Botrychium farrarii'' Legler & Popovich 2024 * '' Botrychium onondagense'' Underw. 1903 * '' Botrychium rubellum'' Stensvold & Farrar 20 ...
