Winged Sumac
''Rhus copallinum'' (''Rhus copallina'' is also used, but this is not consistent with the rules of the International Association for Plant Taxonomy), the winged sumac, shining sumac, dwarf sumac or flameleaf sumac, is a species of flowering plant in the cashew family (Anacardiaceae) that is native to eastern North America. It is a deciduous tree growing to tall and an equal spread with a rounded crown. A 5-year-old sapling will stand about . Description Shining sumac is often cultivated, where it is well-suited to natural and informal landscapes because it has underground runners which spread to provide dense, shrubby cover for birds and wildlife. This species is valued for ornamental planting because of its lustrous dark green foliage which turns a brilliant orange-red in fall. The fall color display is frequently enjoyed along interstate highways, as the plant readily colonizes these and other disturbed sites. The tiny, greenish-yellow flowers, borne in compact, terminal p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
British Museum
The British Museum is a Museum, public museum dedicated to human history, art and culture located in the Bloomsbury area of London. Its permanent collection of eight million works is the largest in the world. It documents the story of human culture from its beginnings to the present.Among the national museums in London, sculpture and decorative art, decorative and applied art are in the Victoria and Albert Museum; the British Museum houses earlier art, non-Western art, prints and drawings. The National Gallery holds the national collection of Western European art to about 1900, while art of the 20th century on is at Tate Modern. Tate Britain holds British Art from 1500 onwards. Books, manuscripts and many works on paper are in the British Library. There are significant overlaps between the coverage of the various collections. Established in 1753, the British Museum was the first public national museum. In 2023, the museum received 5,820,860 visitors, 42% more than the previous y ...

Trees Of Northern America
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, e.g., including only woody plants with secondary growth, only plants that are usable as lumber, or only plants above a specified height. But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhus
Sumac or sumach ( , )—not to be confused with poison sumac—is any of the roughly 35 species of flowering plants in the genus ''Rhus'' (and related genera) of the cashew and mango tree family, Anacardiaceae. However, it is '' Rhus coriaria'' that is most commonly used for culinary purposes. Sumac is prized as a spice—especially in Kurdish, Arab, Lebanese, Turkish, Armenian, Iranian, and other Eastern cuisines —and used as a dye and holistic remedy. The plants grow in subtropical and temperate regions, on nearly every continent except Antarctica and South America. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germination
Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a sporeling from a spore, such as the spores of fungi, ferns, bacteria, and the growth of the pollen tube from the pollen grain of a seed plant. Seed plants Germination is usually the growth of a plant contained within a seed resulting in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting in the emergence of radicle and plumule. The seed of a vascular plant is a small package produced in a fruit or cone after the union of male and female reproductive cells. All fully developed seeds contain an embryo and, in most plant species some store of food reserves, wrapped in a seed coat. Dormant seeds are viable seeds that do not germinate because they require specific internal or environmental stimuli to resume growth. Und ...

Gingivitis
Gingivitis is a non-destructive disease that causes inflammation of the gums; ulitis is an alternative term. The most common form of gingivitis, and the most common form of periodontal disease overall, is in response to bacterial biofilms (also called plaque) that are attached to tooth surfaces, termed ''plaque-induced gingivitis''. Most forms of gingivitis are plaque-induced. While some cases of gingivitis never progress to periodontitis, periodontitis is always preceded by gingivitis. Gingivitis is reversible with good oral hygiene; however, without treatment, gingivitis can progress to periodontitis, in which the inflammation of the gums results in tissue destruction and bone resorption around the teeth. Periodontitis can ultimately lead to tooth loss. Signs and symptoms The symptoms of gingivitis are somewhat non-specific and manifest in the gum tissue as the classic signs of inflammation: *Swollen gums *Bright red gums *Gums that are tender or painful to the touch *B ...

Menorrhagia
Heavy menstrual bleeding (HMB), previously known as menorrhagia or hematomunia, is a menstrual period with excessively heavy flow. It is a type of abnormal uterine bleeding (AUB). Abnormal uterine bleeding can be caused by structural abnormalities in the reproductive tract, skipping ovulation ( anovulation), bleeding disorders, hormonal issues (such as hypothyroidism) or cancer of the reproductive tract. Initial evaluation during diagnosis aims at determining pregnancy status, menopausal status, and the source of bleeding. One definition for diagnosing the condition is bleeding lasting more than 7 days or the loss of more than 80 mL of blood. Treatment depends on the cause, severity, and interference with quality of life. Initial treatments often involve birth control pills, tranexamic acid, danazol and hormonal intrauterine device. Painkillers ( NSAIDs) are also helpful. Surgery can be effective for those whose symptoms are not well-controlled with other treatments. App ...

Coquerel's Sifaka
Coquerel's sifaka (''Propithecus coquereli'') is a Diurnality, diurnal, medium-sized lemur of the sifaka genus ''Sifaka, Propithecus''. It is native to northwest Madagascar. Coquerel's sifaka was once considered a subspecies of Verreaux's sifaka but was eventually granted full species status. It is listed as Critically Endangered on the IUCN Red List due to habitat loss and hunting. In popular culture, the title character in the children's TV show ''Zoboomafoo'' is a Coquerel's sifaka. The species was named after French entomologist Charles Coquerel. Description The dorsal pelage and tail of Coquerel's sifaka are white, and it has maroon patches on the chest and portions of the limbs. The coat is generally dense. Its face is bare and black except for a distinctive patch of white fur along the bridge of the nose. Its naked ears are also black, and its eyes are yellow or orange. The bottom of the lemur's hands and feet are black, while the thighs, arms, and chest are chocolate br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitamin A
Vitamin A is a fat-soluble vitamin that is an essential nutrient. The term "vitamin A" encompasses a group of chemically related organic compounds that includes retinol, retinyl esters, and several provitamin (precursor) carotenoids, most notably Β-Carotene, β-carotene (''beta''-carotene). Vitamin A has multiple functions: growth during embryo development, maintaining the immune system, and healthy vision. For aiding vision specifically, it combines with the protein opsin to form rhodopsin, the light-absorbing molecule necessary for both low-light (scotopic vision) and color vision. Vitamin A occurs as two principal forms in foods: A) retinoids, found in Animal source foods, animal-sourced foods, either as retinol or bound to a fatty acid to become a retinyl ester, and B) the carotenoids Α-Carotene, α-carotene (''alpha''-carotene), β-carotene, Γ-Carotene, γ-carotene (''gamma''-carotene), and the xanthophyll beta-cryptoxanthin (all of which contain β-ionone rings) that ...

Serpentine Soil
Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite. More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to refer to both the soil type and the mineral group which forms its parent materials. Serpentine soils exhibit distinct chemical and physical properties and are generally regarded as poor soils for agriculture. The soil is often reddish, brown, or gray in color due to its high iron and low organic content. Geologically, areas with serpentine bedrock are characteristically steep, rocky, and vulnerable to erosion, which causes many serpentine soils to be rather shallow. The shallow soils and sparse vegetation lead to elevated soil temperatures and dry conditions. Due to their ultramafic origin, ...

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 genus, genera. It is the first work to consistently apply binomial nomenclature, binomial names and was the starting point for the botanical nomenclature, 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-Dahlem Botanical Garden and Botanical Museum, Berlin Botanical Garden; the fifth edition was titled "fourth edition" and was published by Willdenow in four volumes, 1798 (1), 1800 (2), 1801 (31), 1803 (32), 1804 (33), 1805 (41), 1806 (42), rather than the dates printed on the volumes themselves. ...
