John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899. He wrote handbooks on many plant groups, including Amaryllidaceae, Bromeliaceae, Iridaceae, Liliaceae, and ferns. His published works includ''Flora of Mauritius and the Seychelles''(1877) and ''Handbook of the Irideae'' (1892). He married Hannah Unthank in 1860. Their son Edmund was one of twins, and his twin brother died before 1887. John G. Baker was elected a Fellow of the Royal Society in 1878. He was awarded the Veitch Memorial Medal of the Royal Horticultural Society in 1907. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Between 1911 and 1913 he published several important articles on Australian taxonomy. In 1916 he was named as professor of botany. Domin specialised in phytogeography, geobotany and plant taxonomy. He became a member at the Czechoslovak Academy of Sciences, published many scientific works and founded a botany institute at the university. The Domin scale, a commonly used means of classifying a standard area by the number of plant species found in that area, is named after him. In the acad ...

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.

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.

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. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America).
