Vittarioideae
Vittarioideae is a subfamily of the fern family Pteridaceae, in the order Polypodiales. The subfamily includes the previous families Adiantaceae (adiantoids or maidenhair ferns) and Vittariaceae (vittarioids or shoestring ferns). Description The subfamily includes two distinct groups of ferns: the adiantoids, consisting of the single genus ''Adiantum'', and the vittarioids, several genera, including ''Vittaria'', which typically have highly reduced leaves, usually entire, and an epiphytic habit. The ferns historically considered as ''Adiantum'' include both petrophilic and terrestrial plants. The vittarioid ferns are primarily epiphytic in tropical regions and all have simple leaves with sori that follow the veins and lack true indusia; the sori are most often marginal with a false indusium formed from the reflexed leaf margin. The family also includes a species, '' Vittaria appalachiana'', that is highly unusual in that the sporophyte stage of the life cycle is absent. This spe ...

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.

Hecistopteris Pinnatifida
''Hecistopteris pinnatifida'' is a fern species in the ''Vittarioideae'' subfamily of the Pteridaceae. It is endemic to Ecuador. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

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. It is primary at the north-east end; the remainder is ... [...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.

Phytotaxa
''Phytotaxa'' is a peer-reviewed scientific journal for rapid publication on any aspect of systematic botany. It publishes on a wide range of subjects, but focuses on new species, monographs, floras, revisions, reviews, and typification issues. ''Phytotaxa'' covers all plant groups covered by the International Code of Nomenclature for algae, fungi, and plants, including diatoms, fungi, algae, lichens, mosses, hornworts, liverworts, and vascular plants), both living and fossil. The journal was established in 2009 by Maarten Christenhusz and the first issue appeared in October 2009. Authors have the option to publish open access. Abstracting and indexing The journal is abstracted and indexed in Science Citation Index Expanded, Current Contents/Agriculture, Biology & Environmental Sciences, and BIOSIS Previews.

Kurt Polycarp Joachim Sprengel
Kurt Polycarp Joachim Sprengel (3 August 1766 – 15 March 1833) was a German botanist and physician who published an influential multivolume history of medicine, ''Versuch einer pragmatischen Geschichte der Arzneikunde'' (1792–99 in four volumes with later editions running to five) and several other medical reference works. Biography Sprengel was born at Boldekow in Pomerania, and he is considered of German nationality. His father, a clergyman, provided him with a thorough education of wide scope; as boy he distinguished himself as a linguist, in Latin and Greek, and also Arabic; his uncle, Christian Konrad Sprengel (1750–1816), is remembered for his studies in the fertilization of flowers by insects – a subject in which he reached conclusions many years ahead of his time. Spreng. appeared as an author at the age of fourteen, publishing a small work called '' Anleitung zur Botanik für Frauenzimmer'' ("guide to botany for women") in 1780. In 1784 he began to study the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
