Onoclea Sensibilis
''Onoclea sensibilis'', the sensitive fern, also known as the bead fern, is a coarse-textured, medium to large-sized deciduous perennial fern. The name comes from its sensitivity to frost, the fronds dying quickly when first touched by it. It is sometimes treated as the only species in ''Onoclea'', but some authors do not consider the genus monotypic. Description The sterile and fertile fronds of ''Onoclea sensibilis'' have independent stalks originating from the same rhizome, quite different from other ferns. The bright, yellow-green trophophylls (sterile fronds) are deeply pinnatifid and are typically borne at intervals along the creeping rhizome. The sterile fronds are deciduous with trophopods, swollen bases, that serve as over winter storage organs. The sterile fronds of ''O. var. sensibilis'' have a length of 1–1.3 m (3–4 ft) with 5–11 pinnae, leaf pairs, evenly spaced along the stipe. ''O. var. interrupta Maxim.'' fronds are shorter, 20–50 cm (8–20 in) long ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiddlehead
Fiddleheads or fiddlehead greens are the furled fronds of a young fern, harvested for use as a vegetable. Left on the plant, each fiddlehead would unroll into a new frond (circinate vernation). As fiddleheads are harvested early in the season before the frond has opened and reached its full height, they are cut fairly close to the ground. Fiddleheads contain a compound associated with bracken toxicity. The fiddlehead resembles the curled ornamentation (called a ''scroll'') on the end of a stringed instrument, such as a fiddle. It is also called a crozier, after the curved staff used by bishops, which has its origins in the shepherd's crook. Varieties The fiddleheads of certain ferns are eaten as a cooked leaf vegetable. The most popular of these are: * Bracken, ''Pteridium aquilinum'', found worldwide (Toxic if not cooked fully) * Ostrich fern, ''Matteuccia struthiopteris'', found in northern regions worldwide, and the central/eastern part of North America '' (See heal ...

Finnish Language
Finnish ( endonym: or ) is a Uralic language of the Finnic branch, spoken by the majority of the population in Finland and by ethnic Finns outside of Finland. Finnish is one of the two official languages of Finland (the other being Swedish). In Sweden, both Finnish and Meänkieli (which has significant mutual intelligibility with Finnish) are official minority languages. The Kven language, which like Meänkieli is mutually intelligible with Finnish, is spoken in the Norwegian county Troms og Finnmark by a minority group of Finnish descent. Finnish is typologically agglutinative and uses almost exclusively suffixal affixation. Nouns, adjectives, pronouns, numerals and verbs are inflected depending on their role in the sentence. Sentences are normally formed with subject–verb–object word order, although the extensive use of inflection allows them to be ordered differently. Word order variations are often reserved for differences in information structure. Finnish orth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estonian Language
Estonian ( ) is a Finnic language, written in the Latin script. It is the official language of Estonia and one of the official languages of the European Union, spoken natively by about 1.1 million people; 922,000 people in Estonia and 160,000 outside Estonia. Classification Estonian belongs to the Finnic branch of the Uralic language family. The Finnic languages also include Finnish and a few minority languages spoken around the Baltic Sea and in northwestern Russia. Estonian is subclassified as a Southern Finnic language and it is the second-most-spoken language among all the Finnic languages. Alongside Finnish, Hungarian and Maltese, Estonian is one of the four official languages of the European Union that are not of an Indo-European origin. From the typological point of view, Estonian is a predominantly agglutinative language. The loss of word-final sounds is extensive, and this has made its inflectional morphology markedly more fusional, especially with respect to no ...

Cayuga People
The Cayuga ( Cayuga: Gayogo̱hó꞉nǫʼ, "People of the Great Swamp") are one of the five original constituents of the Haudenosaunee (Iroquois), a confederacy of Native Americans in New York. The Cayuga homeland lies in the Finger Lakes region along Cayuga Lake, between their league neighbors, the Onondaga to the east and the Seneca to the west. Today Cayuga people belong to the Six Nations of the Grand River First Nation in Ontario, and the federally recognized Cayuga Nation of New York and the Seneca-Cayuga Tribe of Oklahoma. History Political relations between the Cayuga, the British, and the Thirteen Colonies during the American Revolution were complicated and variable, with Cayuga warriors fighting on both sides (as well as abstaining from war entirely). Most of the Iroquois nations allied with the British, in part hoping to end encroachment on their lands by colonists. In 1778, various Iroquois bands, oft allied with British-colonial loyalists (Tories) conducted a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Danish Language
Danish (; , ) is a North Germanic language spoken by about six million people, principally in and around Denmark. Communities of Danish speakers are also found in Greenland, the Faroe Islands, and the northern German region of Southern Schleswig, where it has minority language status. Minor Danish-speaking communities are also found in Norway, Sweden, the United States, Canada, Brazil, and Argentina. Along with the other North Germanic languages, Danish is a descendant of Old Norse, the common language of the Germanic peoples who lived in Scandinavia during the Viking Era. Danish, together with Swedish, derives from the ''East Norse'' dialect group, while the Middle Norwegian language (before the influence of Danish) and Norwegian Bokmål are classified as ''West Norse'' along with Faroese and Icelandic. A more recent classification based on mutual intelligibility separates modern spoken Danish, Norwegian, and Swedish as "mainland (or ''continental'') Scandinavian", while I ...

Species Plantarum
' (Latin for "The Species of Plants") is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genera. It is the first work to consistently apply binomial names and was the starting point for the naming of plants. Publication ' was published on 1 May 1753 by Laurentius Salvius in Stockholm, in two volumes. A second edition was published in 1762–1763, and a third edition in 1764, although this "scarcely differed" from the second. Further editions were published after Linnaeus' death in 1778, under the direction of Karl Ludwig Willdenow, the director of the Berlin Botanical Garden; the fifth edition (1800) was published in four volumes. Importance ' was the first botanical work to consistently apply the binomial nomenclature system of naming to any large group of organisms (Linnaeus' tenth edition of ' would apply the same technique to animals for the first time in 1758). Prior to this work, a plant spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angiopteris
''Angiopteris'' is a genus of huge evergreen ferns from the family Marattiaceae, found throughout the paleotropics from Madagascar to the South Pacific islands. Species of smaller stature with elongate synangia and creeping rhizomes are sometimes segregated into the genus '' Archangiopteris'', and a once-pinnate monotypic segregate genus has been called ''Macroglossum'', but molecular data supports inclusion of these taxa within a broad concept of ''Angiopteris''. ''Angiopteris evecta'' has been introduced and naturalized in Hawaii, Jamaica, and parts of Central America, where it has become an invasive weed in lower elevation drainages. They feature a large, erect, woody rhizome with a wide base supported by thick roots. The fronds are deltoid, pinnate, long, with spreading leaflets.Ellison, Don (1999) Cultivated Plants of the World. London: New Holland (1st ed.: Brisbane: Flora Publications International, 1995) ''Angiopteris'' is unique among ferns in having explosively disp ...

Onoclea
''Onoclea'' is a genus of plants in the family Onocleaceae, native to moist habitats in eastern Asia and eastern North America. They are deciduous ferns with sterile fronds arising from creeping rhizomes in spring, dying down at first frost. Fertile fronds appear in late summer. Depending on the authority, the genus contains one to five species.

Sporangium
A sporangium (; from Late Latin, ) is an enclosure in which spores are formed. It can be composed of a single cell or can be multicellular. Virtually all plants, fungi, and many other lineages form sporangia at some point in their life cycle. Sporangia can produce spores by mitosis, but in nearly all land plants and many fungi, sporangia are the site of meiosis and produce genetically distinct haploid spores. Fungi In some phyla of fungi, the sporangium plays a role in asexual reproduction, and may play an indirect role in sexual reproduction. The sporangium forms on the sporangiophore and contains haploid nuclei and cytoplasm. Spores are formed in the sporangiophore by encasing each haploid nucleus and cytoplasm in a tough outer membrane. During asexual reproduction, these spores are dispersed via wind and germinate into haploid hyphae. Although sexual reproduction in fungi varies between phyla, for some fungi the sporangium plays an indirect role in sexual reprod ...
