Field Scabious
''Knautia arvensis'', commonly known as field scabious, is a herbaceous perennial species of flowering plant in the honeysuckle family Caprifoliaceae. Description It is a perennial plant that grows between . It prefers grassy places and dry soils, avoiding heavy soils, and flowers between July and September. The flowers are borne on inflorescences in the form of heads; each head contains many small florets. The head is flatter than in similar species, such as devil's bit scabious (''Succisa pratensis'') and small scabious (''Scabiosa columbaria''). There are 4 stamens in each floret, and 1 notched long stigma. The fruit is nut like, cylindrical and hairy, in size. It has a tap root. The stem has long stiff hairs angled downwards. The leaves form a basal rosette, are paired on the stem, the lowest typically long, spear shaped, whereas the upper are smaller. There are no stipules. Ecology It is occasionally used by the marsh fritillary as a foodplant instead of its usu ... [...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 coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsh Fritillary
The marsh fritillary (''Euphydryas aurinia'') is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. The larvae are dependent on the host food plant ''Succisa pratensis'' not only for feeding but also for hibernation, because silken webs are formed on the host plant as the gregarious larvae enter hibernation. Females lay eggs in batches on the host plant and are, like other batch-layers, selective about the location of oviposition because offspring survivorship levels for batch-layers are more tied to location selection than they are for single-egg layers. As of 2019 the butterfly's global conservation status is considered of least concern, but it has faced rapid decline and is considered regionally vulnerable or endangered over much ...

Aphantopus Hyperantus
The ringlet (''Aphantopus hyperantus'') is a butterfly in the family Nymphalidae. It is only one of the numerous "ringlet" butterflies in the tribe Satyrini. Range The ringlet is a widely distributed species found throughout much of the Palearctic realm. In Europe it is common in most countries but absent from northern Scandinavia, peninsular Italy (found in northern Italy), Portugal, southern and central Spain (found in Cantabrian Mountains and the eastern Pyrenees), the Mediterranean islands and North Africa. In Greece it is found in northern regions (Macedonia, Thessaly). Beyond Europe it is found across much of temperate Asia including Russia, Siberia, Mongolia, China and Korea. Description ''Aphantopus hyperantus'' is a medium-sized butterfly with a wingspan of up to 35 to 42 millimeters. The wing upper and lower sides are solid brown with small, yellowish-rimmed eyespots. The newly emerged ringlet has a velvety appearance and is almost black with a white fringe t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meadows
A meadow ( ) is an open habitat, or field, vegetated by grasses, herbs, and other non-woody plants. Trees or shrubs may sparsely populate meadows, as long as these areas maintain an open character. Meadows may be naturally occurring or artificially created from cleared shrub or woodland. They can occur naturally under favourable conditions (see perpetual meadows), but they are often maintained by humans for the production of hay, fodder, or livestock. Meadow habitats, as a group, are characterized as "semi-natural grasslands", meaning that they are largely composed of species native to the region, with only limited human intervention. Meadows attract a multitude of wildlife, and support flora and fauna that could not thrive in other habitats. They are ecologically important as they provide areas for animal courtship displays, nesting, food gathering, pollinating insects, and sometimes sheltering, if the vegetation is high enough. There are multiple types of meadows, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Knaut
Christian Knaut (August 16, 1656 – April 11, 1716) was a German physician, botanist and librarian born in Halle an der Saale. His older brother, Christoph Knaut (1638–1694) was also a physician and botanist. He studied medicine at the University of Leipzig, where he had as instructors Gottfried Welsch, Paul Amman, Michael Ettmüller and Johannes Bohn. In 1682 he obtained his doctorate from the University of Jena with a dissertation titled ''De fermentatione in sanguine non existente''. Afterwards he returned to Halle, where he served as a librarian and personal physician to Prince Emanuel Lebrecht of Anhalt-Köthen. As a librarian he was the author of a chronicle and description involving the counties of Ballenstädt and Aschersleben (1698). As a botanist he published ''Compendium Botanicum sive Methodus plantarum genuina'', in which he provided a classification system for flowering plants based on petal number and arrangement.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...

Bubonic Plague
Bubonic plague is one of three types of plague caused by the plague bacterium ('' Yersinia pestis''). One to seven days after exposure to the bacteria, flu-like symptoms develop. These symptoms include fever, headaches, and vomiting, as well as swollen and painful lymph nodes occurring in the area closest to where the bacteria entered the skin. Acral necrosis, the dark discoloration of skin, is another symptom. Occasionally, swollen lymph nodes, known as " buboes," may break open. The three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. Bubonic plague is mainly spread by infected fleas from small animals. It may also result from exposure to the body fluids from a dead plague-infected animal. Mammals such as rabbits, hares, and some cat species are susceptible to bubonic plague, and typically die upon contraction. In the bubonic form of plague, the bacteria enter through the skin through a flea bite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scabies
Scabies (; also sometimes known as the seven-year itch) is a contagious skin infestation by the mite '' Sarcoptes scabiei''. The most common symptoms are severe itchiness and a pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin. Scabies is caused by infection with the female mite '' Sarcoptes scabiei ''var.'' hominis'', an ectoparasite. The mites burrow into the skin to live and deposit eggs. The symptoms of scabies are due to an allergic reaction to the mites. Often, only bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemaris Tityus
''Hemaris tityus'', the narrow-bordered bee hawk-moth, is a moth of the family Sphingidae which is native to the Palearctic. Range It has a wide range, from Ireland across temperate Europe to the Ural Mountains, western Siberia, Novosibirsk and the Altai. It is also known from the Tian Shan eastwards across Mongolia to north-eastern China and southwards to Tibet. There is a separate population found from Turkey to northern Iran. Biology It appears in May and June and is a lively day-flier (unlike most other sphingids), generally active from mid-morning to mid-afternoon. It frequents marshy woodland and damp moorland, and has a wide distribution across temperate Europe and Western Asia, but is generally quite scarce. The larvae feed on devil's-bit scabious (''Succisa pratensis'') and field scabious (''Knautia arvensis''). Identification It is distinguished from '' H. fuciformis'' by the narrow band of scaling along the outer wing margin, and the forewing's undivided discal cell. ...

Stipules
In botany, a stipule is an outgrowth typically borne on both sides (sometimes on just one side) of the base of a leafstalk (the petiole). Stipules are considered part of the anatomy of the leaf of a typical flowering plant, although in many species they may be inconspicuous —or sometimes entirely absent, and the leaf is then termed ''exstipulate''. (In some older botanical writing, the term "stipule" was used more generally to refer to any small leaves or leaf-parts, notably prophylls.) The word ''stipule'' was coined by Linnaeus''Concise English Dictionary'' Wordsworth Editions Ltd. 1994, from Latin ''stipula'', straw, stalk. Types of stipules General characteristics The position of stipules on a plant varies widely from species to species, though they are often located near the base of a leaf. Stipules are most common on dicotyledons, where they appear in pairs alongside each leaf. Some monocotyledon plants display stipule-like structures, but only display one per leaf ...

Thomas Coulter
Thomas Coulter (1793–1843), of Dundalk, was an Irish physician, botanist and explorer. He was a member of the Royal Irish Academy, a fellow of Trinity College, Dublin, and founder of that college's herbarium. After completing a medical degree in Dublin, Coulter studied botany in Geneva for 17 months under Swiss taxonomist Augustin de Candolle. He then left Switzerland and became a physician with the Real del Monte Company in Mexico. During this period he collected and catalogued plants in the region. He eventually left Mexico and travelled the world exploring many countries and conducting botanical research culminating in Arizona and Alta California in the early 19th century. He returned to Ireland in 1834 and became the founding curator of the herbarium at Trinity College, Dublin. Though he was a physician by profession, Coulter achieved success in different fields and is best remembered as an explorer and a pioneer in botany. References External links Trinity College He ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. ...
