Danish Scurvygrass
''Cochlearia danica'', or Danish scurvygrass, is a flowering plant of the genus ''Cochlearia'' in the family Brassicaceae. A salt-tolerant (normally) coastal plant which is now flourishing along roads and motorways in Europe, especially under the crash barriers in the central reservation. Its success has been attributed to its ability to survive the effects of salts distributed by gritters in winter and its small seeds being spread by the high speed of cars in the fast lane. Full of vitamin C, it gets its name from sailors chewing it to avoid scurvy Scurvy is a deficiency disease (state of malnutrition) resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, fatigue, and sore arms and legs. Without treatment, anemia, decreased red blood cells, gum d .... The mauve flowers are 4-5mm in diameter.

Cochlearia Groenlandica
''Cochlearia groenlandica'', known in English as polar scurvygrass or Greenland scurvy-grass, is a flowering plant of the scurvy-grass genus in the cabbage family. Description ''Cochlearia groenlandica'' grows as a solitary plants, with a single root and a branched caudex at the surface of the ground. Plants live two to five years. First or second year plants have rosettes, circular arrangement of leaves, at ground level. Flowering occurs in the last year of life with the rosettes of leaves die, but stems remain until the seeds are fully ripe. Each plant sprouts a small number of stems, usually branched towards the ends, that range in size from , though more typically . The stems are may grow straight upwards or be decumbent, growing along the ground and only turning up at the ends. The basal leaves are attached to the caudex by petioles, leaf stems that range from 0.2 to 10 centimeters in length. They are deltate to ovate in shape and 0.3 to 2.5 cm in length and ju ...

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] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochlearia
''Cochlearia'' (scurvy-grass or spoonwort) is a genus of about 30 species of annual and perennial herbs in the family Brassicaceae. They are widely distributed in temperate and arctic areas of the northern hemisphere, most commonly found in coastal regions, on cliff-tops and salt marshes where their high tolerance of salt enables them to avoid competition from larger, but less salt-tolerant plants; they also occur in alpine habitats in mountains and tundra. They form low, rounded or creeping plants, typically 5–20 cm tall. The leaves are smoothly rounded, roughly spoon-shaped (the scientific name ''Cochlearia'' derives from the Latinized form, ''cocleare'', of the Greek κοχλιάριον, ''kokhliárion'', a spoon; this a diminutive of κόχλος, ''kókhlos'', seashell), or in some species, lobed; typically 1–5 cm long, and with a fleshy texture. The flowers are white with four petals and are borne in short racemes. Selected species About 30 species are u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brassicaceae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important Family (biology), family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in Rosette (botany), rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gritters
A winter service vehicle (WSV), or snow removal vehicle, is a vehicle specially designed or adapted to clear thoroughfares of ice and snow. Winter service vehicles are usually based on a dump truck chassis, with adaptations allowing them to carry specially designed snow removal equipment. Many authorities also use smaller vehicles on sidewalks, footpaths, and cycleways. Road maintenance agencies and contractors in temperate or polar areas often own several winter service vehicles, using them to keep the roads clear of snow and ice and safe for driving during winter. Airports use winter service vehicles to keep aircraft surfaces, runways, and taxiways free of snow and ice, which, besides endangering aircraft takeoff and landing, can interfere with the aerodynamics of the craft. The earliest winter service vehicles were snow rollers, designed to maintain a smooth, even road surface for sleds, although horse-drawn snowplows and gritting vehicles are recorded in use as early as 18 ...

Vitamin C
Vitamin C (also known as ascorbic acid and ascorbate) is a water-soluble vitamin found in citrus and other fruits, berries and vegetables. It is also a generic prescription medication and in some countries is sold as a non-prescription dietary supplement. As a therapy, it is used to prevent and treat scurvy, a disease caused by vitamin C deficiency. Vitamin C is an essential nutrient involved in the repair of tissue, the formation of collagen, and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. Vitamin C may be taken by mouth or by intramuscular, subcutaneous or intravenous injection. Various health claims exist on the basis that moderate vitamin C deficiency increases disease risk, such as for the common cold, cancer or COVID-19. There are also claims of benefits from vitamin C supplementation in excess of the recommended d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scurvy
Scurvy is a deficiency disease (state of malnutrition) resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, fatigue, and sore arms and legs. Without treatment, anemia, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens, there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and Kidney dialysis, dialysis. While many animals produce their vitamin C, humans and a few others do not. Vitamin C, an antioxidant, is required to make the building blocks for collagen, carnitine, and catecholamines, and assists the intestines in the absorption of iron from foo ...

Plants Described In 1753
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants ( hornworts, liverworts, mosses, lycophytes, ferns, conifers and o ...
