Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, 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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Britannica
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is '' fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms '' gut flora'' or '' skin flora'' for purposes of specificity. 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 communi ...

Perennial
In horticulture, the term perennial ('' per-'' + '' -ennial'', "through the year") is used to differentiate a plant from shorter-lived annuals and biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as herbaceous perennials. However, depending on the rigours of the local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a peren ...

Catkin
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind- pollinated ( anemophilous) but sometimes insect-pollinated (as in '' Salix''). It contains many, usually unisexual flowers, arranged closely along a central stem that is often drooping. Catkins are found in many plant families, including Betulaceae, Fagaceae, Moraceae, and Salicaceae. Occurrence Catkin-bearing plants include many trees or shrubs such as birch, willow, aspen, hickory, sweet chestnut, and sweetfern (''Comptonia''). In many of these plants, only the male flowers form catkins, and the female flowers are single ( hazel, oak), a cone ( alder), or other types ( mulberry). '' Corylus jacquemontii'' has male catkins and also female spikes. In other plants (such as poplar), both male and female flowers are borne in catkins. '' Populus alba'' has male catkins which are grey and the female catkins are greyish-green. While the blooming months ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boggart
A boggart is a supernatural being from English folklore. The dialectologist Elizabeth Mary WElizabeth Wright described the boggart as 'a generic name for an apparition'; folklorist Simon Young defines it as 'any ambivalent or evil solitary supernatural spirit'. Halifax, West Yorkshire, Halifax folklorist Kai Roberts states that boggart ‘might have been used to refer to anything from a hilltop hobgoblin to a household faerie, from a headless apparition to a proto-typical poltergeist’. As these wide definitions suggest boggarts are to be found both in and out of doors, as a household spirit, or a malevolent spirit defined by local geography, a ''genius loci'' inhabiting topographical features. The 1867 book ''Lancashire Folklore'' by John Harland, Harland and Wilkinson, makes a distinction between "House boggarts" and other types. Typical descriptions show boggarts to be Evil, malevolent. It is said that the boggart crawls into people's beds at night and puts a clammy hand on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chenopodium Bonus-henricus
''Blitum bonus-henricus'' ( syn. ''Chenopodium bonus-henricus''), also called Good-King-Henry, poor-man's asparagus, perennial goosefoot, Lincolnshire spinach, Markery, English mercury, or mercury goosefoot, is a species of goosefoot which is native to much of central and southern Europe. Good-King-Henry has been grown as a vegetable in cottage gardens for hundreds of years, although this dual-purpose vegetable is now rarely grown and the species is more often considered a weed. Description It is an annual or perennial plant growing up to tall. The leaves are long and broad, triangular to diamond-shaped, with a pair of broad pointed lobes near the base, with a slightly waxy, succulent texture. The flowers are produced in a tall, nearly leafless spike long; each flower is very small ( in diameter), greenish, with five sepals. The seeds are reddish-green, 2–3 mm in diameter. Taxonomy The species was described in 1753 by Carl Linnaeus as ''Chenopodium bonus-henricus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coppicing
Coppicing is the traditional method in woodland management of cutting down a tree to a tree stump, stump, which in many species encourages new Shoot (botany), shoots to grow from the stump or roots, thus ultimately regrowing the tree. A forest or grove that has been subject to coppicing is called a copse or coppice, in which young tree stems are repeatedly cut down to near ground level. The resulting living stumps are called Living stump, stools. New growth emerges, and after a number of years, the coppiced trees are harvested, and the cycle begins anew. Pollarding is a similar process carried out at a higher level on the tree in order to prevent grazing animals from eating new shoots. ''Daisugi'' (台杉, where ''sugi'' refers to Japanese cedar) is a similar Japanese technique. Many silviculture practices involve cutting and regrowth; coppicing has been of significance in many parts of lowland temperate Europe. The widespread and long-term practice of coppicing as a landscape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
