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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaphoglossum
''Elaphoglossum'' is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Taxonomy ''Elaphoglossum'' was first described in 1841 by John Smith, who attributed the name to Heinrich Schott. The name ''Elaphoglossum'' in botanical Latin means 'stag's tongue', in reference to the shape and texture of the leaf fronds.Gledhill D. 1996. ''The Names of Plants''. Cambridge University Press. Species The genus has a large number of species. The Pteridophyte Phylogeny Group classification of 2016 (PPG I) suggested there were about 600; ''Plants of the World Online'' and the ''Checklist of Ferns and Lycophytes of the World'' both listed at least 730 . Species include: *''Elaphoglossum conforme'' (Sw.) J.Sm.

Dryopteridaceae
The Dryopteridaceae are a Family (biology), family of leptosporangiate ferns in the Order (biology), order Polypodiales. They are known Common name, colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae ''Sensu, sensu lato''. The family contains about 1700 species and has a cosmopolitan distribution. Species may be terrestrial plant, terrestrial, epipetric, hemiepiphyte, hemiepiphytic, or epiphytic. Many are Gardening, cultivated as ornamental plants. The largest genera are ''Elaphoglossum'' (600+), ''Polystichum'' (260), ''Dryopteris'' (225), and ''Ctenitis'' (150). These four genera contain about 70% of the species. Dryopteridaceae Evolutionary radiation, diverged from the other families in eupolypods I about 100 million years ago.
