Onychium Japonicum
''Onychium japonicum'' is a species of fern in the family Pteridaceae. Taxonomy The species was first described in 1784 by Carl Peter Thunberg as ''Trichomanes japonicum''. In 1825, Blume used the name "''Onychium''" for a genus of orchids, but this was illegitimate since it had been used in 1820 for the fern genus. Blume also used the combination "''Onychium japonicum''" for an orchid (now ''Dendrobium moniliforme ''Dendrobium moniliforme'', known as Shihu in Chinese and Sekkoku in Japanese, is a species of orchid. It is native to Japan, Korea, China, the Himalayas, and northern Indochina. ''Dendrobium moniliforme'' is the type species for the genus ''Den ...''). In 1848, Kunze transferred ''Trichomanes japonicum'' to the fern genus ''Onychium'' as ''Onychium japonicum''. The name ''Onychium japonicum'' (Thunb.) Kunze is conserved against ''Onychium japonicum'' Blume. References Pteridaceae Plants described in 1784 {{Pteridaceae-stub ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes 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 leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled 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) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pteridoideae
''Pteridoideae'' is one of the five subfamilies of the fern family Pteridaceae. This subfamily contains about 14 genera and around 400 species. Taxonomy Phylogeny The following diagram shows a likely phylogenic relationship between Pteridoideae and the other the Pteridaceae subfamilies. The cladogram below shows one hypothesis for the evolutionary relationships among the genera of the Pteridoideae, based on a maximum likelihood analysis using six plastid markers. The authors of the study identified four major clades. The ''Pteris'' and JAPSTT clades are found worldwide; the GAPCC clade is pantropical; and the ''Actiniopteris''+''Onychium'' clade is restricted to the Old World. Genera The Pteridophyte Phylogeny Group classification of 2016 (PPG I) recognized 13 genera. Shortly afterwards, the genus ''Gastoniella'' was created for three species formerly placed in ''Anogramma'' which a molecular phylogenetic analysis had shown to be distinct. *'' Actiniopteris'' Link *'' Anogra ...

Pteridaceae
Pteridaceae is a family of ferns in the order Polypodiales, including some 1150 known species in ca 45 genera (depending on taxonomic opinions), divided over five subfamilies. The family includes four groups of genera that are sometimes recognized as separate families: the adiantoid, cheilanthoid, pteridoid, and hemionitidoid ferns. Relationships among these groups remain unclear, and although some recent genetic analyses of the Pteridales suggest that neither the family Pteridaceae nor the major groups within it are all monophyletic, as yet these analyses are insufficiently comprehensive and robust to provide good support for a revision of the order at the family level. Description Members of Pteridaceae have creeping or erect rhizomes. The leaves are almost always compound and have linear sori that are typically on the margins of the leaves and lack a true indusium, typically being protected by a false indusium formed from the reflexed margin of the leaf.
