American Fern Society
The American Fern Society was founded in 1893. Today, it has more than 1,000 members around the world, with various local chapters. Among its deceased members, perhaps the most famous is Oliver Sacks, who became a member in 1993. Willard N. Clute was the founder of the society, originally establishing it as the Linnaean Fern Chapter of the Agassiz Association The Agassiz Association was a society founded in 1875 for the study of natural science, named for Swiss-American naturalist Louis Agassiz. Its founder and first president was Harlan Hoge Ballard (1853–1934). History According to its Constitutio .... The chapter had two comprehensive group meetings, one in 1898 and another in 1900. The chapter consisted of small regional divisions and circulated reports by mail from member to member. In 1905 the members of the Linnean Fern Chapter separated from the Agassiz Association and formed the American Fern Society. The society has published the '' American Fern Journal'', a techn ...

Oliver Sacks
Oliver Wolf Sacks, (9 July 1933 – 30 August 2015) was a British neurologist, naturalist, historian of science, and writer. Born in Britain, Sacks received his medical degree in 1958 from The Queen's College, Oxford, before moving to the United States, where he spent most of his career. He interned at Mount Zion Hospital in San Francisco and completed his residency in neurology and neuropathology at the University of California, Los Angeles (UCLA). After a fellowship at the Albert Einstein College of Medicine, he served as neurologist at Beth Abraham Hospital's chronic-care facility in the Bronx, where he worked with a group of survivors of the 1920s sleeping sickness encephalitis lethargica, who had been unable to move on their own for decades. His treatment of those patients became the basis of his 1973 book '' Awakenings'', which was adapted into an Academy Award-nominated feature film in 1990, starring Robin Williams and Robert De Niro. His numerous other best-selling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Agassiz Association
The Agassiz Association was a society founded in 1875 for the study of natural science, named for Swiss-American naturalist Louis Agassiz. Its founder and first president was Harlan Hoge Ballard (1853–1934). History According to its Constitution, the Agassiz Association's purpose was "to collect, study, and preserve natural objects and facts." Each Chapter of the Association was allowed to choose its own officers and make its own by-laws. By 1880 there were chapters in Massachusetts, New York State, and Pennsylvania. By 1884 the Association had about 7000 members and about 600 Chapters. For some years, ''St. Nicholas Magazine'' was the official organ of communication between the Association and its members. The Association was incorporated in 1892. Ballard's successor as president was Edward F. Bigelow. The American Fern Society and the Wilson Ornithological Society originated as Chapters of the Agassiz Association.

The Fern Bulletin
''The Fern Journal'' was a quarterly scientific journal specializing in pteridology. Willard N. Clute was the editor-in-chief of ''The Fern Bulletin'' throughout its years of publication. The Linnaean Fern Chapter of the Agassiz Association published the first 4 volumes (1893–1896) under the title ''The Linnaean Fern Bulletin'' and volumes 5 through 12 (1897–1904) under the title ''The Fern Bulletin''. In 1905 the members of the Linnaean Fern Chapter created an independent organization called the American Fern Society (and the Linnaean Fern Chapter became defunct). The American Fern Society continued to use ''The Fern Bulletin'' as its official organ until 1910 when the Society's official organ became the newly created ''American Fern Journal''. The Society ceased publication of ''The Fern Bulletin'' in 1912. There are 20 volumes of ''The Fern Bulletin'', containing original research, field notes, botanical discoveries, and news of interest to members. ''The Bryologist'' origin ...

Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridomania
Pteridomania or fern fever was a Victorian craze for ferns. Decorative arts of the period presented the fern motif in pottery, glass, metal, textiles, wood, printed paper, and sculpture, with ferns "appearing on everything from christening presents to gravestones and memorials". Description ''Pteridomania'', meaning ''Fern Madness'' or ''Fern Craze'', a compound of ''Pteridophytes'' and '' mania'', was coined in 1855 by Charles Kingsley in his book ''Glaucus, or the Wonders of the Shore'': According to one author: Collection and cultivation The collection of ferns drew enthusiasts from different social classes and it is said that "even the farm labourer or miner could have a collection of British ferns which he had collected in the wild and a common interest sometimes brought people of very different social backgrounds together". For some a fashionable hobby and for others a more serious scientific pursuit, fern collecting became commercialised with the sale of mer ...

Botanical Societies
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", "herbs" "grass", or "fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, medici ...

Ferns Of The United States
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.
