Asplenium Ruta-muraria
''Asplenium ruta-muraria'' is a species of fern commonly known as wall-rue (but which, as a fern, is not by any means closely related to common rue). It is a very small epipetric species, growing exclusively on limestone and other calcareous rocks. Its fronds are bluish-green and are heavily sub-divided, becoming up to 12 cm in length. Taxonomy Linnaeus first gave wall-rue the binomial ''Asplenium ruta-muraria'' in his '' Species Plantarum'' of 1753. A global phylogeny of ''Asplenium'' published in 2020 divided the genus into eleven clades, which were given informal names pending further taxonomic study. ''A. ruta-muraria'' belongs to the "''Pleurosorus'' subclade" of the "''Pleurosorus'' clade". The ''Pleurosorus'' clade has a worldwide distribution; members are generally small and occur on hillsides, often sheltering among rocks in exposed habitats. ''A. ruta-muraria'' is exceptional within the subclade for its lack of hairs on the leaf. The phylogeny suggests t ...

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]   |

Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Ferns Of Europe
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.

Flora Of Lebanon
The flora of Lebanon includes approximately 2,600 plant species. Situated on the eastern coast of the Mediterranean Basin, Lebanon is a reservoir of plant diversity and one of the world's biodiversity hotspots for conservation priorities. Endemic species constitute 12% of the Lebanese flora; 221 plant species are broad endemics and 90 are narrow endemics.. Important Plant Areas (IPAs) featuring the country exceptional botanical richness were defined in 2018. The natural vegetation of Lebanon has been threatened by overexploitation and fragmentation as a result of urban expansion, overgrazing, tourism and the impact of warfare. The cedar of Lebanon is the national symbol of the country; growing in the Lebanon Mountain range, these trees have been heavily harvested over the years for their valuable timber and few mature trees still remain. Nevertheless, Lebanon is more heavily wooded than most other countries in the region and pine, oak, fir, beech, cypress and juniper are to be f ...

Flora Of England
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Asplenium
''Asplenium'' is a genus of about 700 species of ferns, often treated as the only genus in the family Aspleniaceae, though other authors consider ''Hymenasplenium'' separate, based on molecular phylogenetic analysis of DNA sequences, a different chromosome count, and structural differences in the rhizomes. The type species for the genus is ''Asplenium marinum''. The most common vernacular name is spleenworts, applied to the more "typical" species. '' A. nidus'' and several similar species are called bird's-nest ferns, the ''Camptosorus'' group is known as walking ferns, and distinct names are applied to some other particularly well-known species. Taxonomy and genetics Many groups of species have been separated from ''Asplenium'' as segregate genera. These include ''Camptosorus'', ''Ceterach'', ''Phyllitis'', and ''Tarachia'', but these species can form hybrids with other ''Asplenium'' species and because of this are usually included in a more broadly defined ''Asplenium''.

Clinton County, Iowa
Clinton County is a county located in the U.S. state of Iowa. As of the 2020 census, the population was 46,460. Its county seat is Clinton. Its name is in honor of the seventh Governor of New York State, DeWitt Clinton. Clinton County comprises the Clinton, IA Micropolitan Statistical Area, which is also included in the Davenport–Moline–Rock Island Metropolitan Statistical Area. History Clinton County was formed on December 21, 1837. It was named for DeWitt Clinton, a Governor of New York and most ardent advocate for the construction of the Erie Canal. The cities of DeWitt and Clinton were also named after him. In 1835, Elijah Buell built a log cabin for himself and his family and was thus the first settler of the region.
