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.

Elaphoglossoideae
Elaphoglossoideae is a subfamily of the fern family Dryopteridaceae. It has previously been regarded as the family Elaphoglossaceae. As circumscribed by the Pteridophyte Phylogeny Group in their 2016 classification (PPG I), the subfamily excludes the Polybotryoideae, which are kept separate. It can be divided into three clades: the bolbitidoid ferns (''Arthrobotrya'', ''Bolbitis'', '' Elaphoglossum'', ''Lomagramma'', ''Mickelia'', ''Teratophyllum''), genus ''Pleocnemia'', sister clade to the bolbititoids, and the lastreopsid ferns (''Lastreopsis'', ''Megalastrum'', ''Parapolystichum ''Parapolystichum'' is a genus of ferns in the family Dryopteridaceae, subfamily Elaphoglossoideae, in the Pteridophyte Phylogeny Group classification of 2016 (PPG I).

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] |
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] |
Pteridophyte Phylogeny Group
The Pteridophyte Phylogeny Group, or PPG, is an informal international group of systematic botanists who collaborate to establish a consensus 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). 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 suborders, as well as families not placed in a suborder: Classification to subfamily level To the level of subfamily, the PPG I classification is as follows. *Class Lycopodi ...

John Smith (botanist)
John Smith (1798–1888) was a British botanist who was the first curator at Royal Botanic Gardens, Kew (Kew Gardens), starting in 1841. He had first been employed at the gardens as a stove boy (stoking stoves to warm the greenhouses) in 1822. Along with the directors, Sir William Jackson Hooker and Sir Joseph Hooker, he oversaw the conversion of the gardens from private royal gardens to public gardens when Queen Victoria converted them, possibly saving them from oblivion. He further prevented the gardens from catastrophic decline during the late 19th century when they were neglected in funding priorities. According to the Kew website, "It is significant that when stove-boy-Smith arrived at Kew, 40 species of fern were grown but when Curator Smith retired, there were 1,084." He was born in Pittenweem, Scotland, in 1798. He died 12 February 1888 at Park House, Kew Road The A307 road runs through SW London and NW Surrey.

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images.
