Tectariaceae
Tectariaceae is a family of leptosporangiate ferns in the order Polypodiales. 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 Tectarioideae of a very broadly defined family Polypodiaceae '' sensu lato''. The family comprises seven genera, of which '' Tectaria'' is by far the largest. Taxonomy In 1990, Karl U. Kramer and coauthors treated '' Pleocnemia'' and 7 of the currently recognized genera as a subfamily of Dryopteridaceae.Karl U. Kramer (with Richard E. Holttum, Robin C. Moran, and Alan R.

Arthropteris
''Arthropteris'' is a small genus of ferns in family Tectariaceae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It was previously placed in the families Oleandraceae or Davalliaceae. The genus is native to Australia, Europe, Asia and Africa. Around 12 to 21 species are considered part of this genus. The name ''Arthropteris'' is from the Greek, meaning "jointed fern", referring to the joint at the base of the petiole.Les Robinson - Field Guide to the Native Plants of Sydney, page 309 The type species is ''Arthropteris tenella''.Hooker, J.D.

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 fe ...
