Crataegus Mexicana
''Crataegus mexicana'' is a species of hawthorn known by the common names , , and Mexican hawthorn. It is native to the mountains of Mexico and parts of Guatemala, and has been introduced in the Andes. The fruit of this species is one of the most useful among hawthorns. ''Crataegus pubescens'' Steud. is a nomenclaturally illegitimate name (for ''Crataegus gracilior'' J.B.PhippsPhipps JB (1997) Monograph of Northern Mexican ''Crataegus'' (Rosaceae, subfam. Maloideae). Botanical Research Institute of Texas, Fort Worth, Texas, U.S.A.) that is commonly misapplied to this species. Etymology , the Mexican name for this fruit, comes from the Nahuatl word which means 'stone fruit'. The alternative (and ambiguous) name (or in Guatemala) means 'little apple' in Spanish. The generic name, ''Crataegus'', is derived from a Latinized Greek compound word literally meaning 'strong sharp,' in reference to the strong wood, and thorny habitus of several species.

José Mariano Mociño
José Mariano Mociño Suárez Lozano (24 September 1757 – 12 June 1820), or simply José Mariano Mociño, was a naturalist from Mexico. After having studied philosophy and medicine, he conducted early research on the botany, geology, and anthropology of his country and other parts of North America. Biography He was born in Temascaltepec (modern-day Mexico State) in 1757. Being poor, he worked in many different jobs to study in the ''Seminario Tridentino de México'', where he devoted himself especially to physics, mathematics, botany, and chemistry. In 1778 he graduated in philosophy. In 1791 he was called to join the scientific expedition of Martín de Sessé, the Royal Botanical Expedition, which had started in 1787. They traveled across New Spain, reaching the most inhospitable places of the Empire, being especially notable his trips to the Pacific Northwest. Although the pay for his job was minimal, he created one of the most important natural history collections of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower
Flowers, also known as blooms and blossoms, are the reproductive structures of flowering plants ( angiosperms). Typically, they are structured in four circular levels, called whorls, around the end of a stalk. These whorls include: calyx, modified leaves; corolla, the petals; androecium, the male reproductive unit consisting of stamens and pollen; and gynoecium, the female part, containing style and stigma, which receives the pollen at the tip of the style, and ovary, which contains the ovules. When flowers are arranged in groups, they are known collectively as inflorescences. Floral growth originates at stem tips and is controlled by MADS-box genes. In most plant species flowers are heterosporous, and so can produce sex cells of both sexes. Pollination mediates the transport of pollen to the ovules in the ovaries, to facilitate sexual reproduction. It can occur between different plants, as in cross-pollination, or between flowers on the same plant or even the same f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homonym (biology)
In biology, a homonym is a name for a taxon that is identical in spelling to another such name, that belongs to a different taxon. The rule in the International Code of Zoological Nomenclature is that the first such name to be published is the senior homonym and is to be used (it is "valid name (zoology), valid"); any others are junior homonyms and must be replaced with new names. It is, however, possible that if a senior homonym is archaic, and not in "prevailing usage," it may be declared a ''nomen oblitum'' and rendered unavailable, while the junior homonym is preserved as a ''nomen protectum''. :For example: :*Georges Cuvier, Cuvier proposed the genus ''Echidna'' in 1797 for the echidna, spiny anteater. :*However, Johann Reinhold Forster, Forster had already published the name ''Echidna'' in 1777 for a genus of moray eels. :*Forster's use thus has Priority (biology), priority, with Cuvier's being a junior homonym. :*Johann Karl Wilhelm Illiger, Illiger published the replace ...

International Code Of Botanical Nomenclature
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN or ICNafp) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. For fungi the ''Code'' was revised by the ''San Juan Chapter F'' in 2018. The 2025 edition of ICBN, the '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diarrhea
Diarrhea (American English), also spelled diarrhoea or diarrhœa (British English), is the condition of having at least three loose, liquid, or watery bowel movements in a day. It often lasts for a few days and can result in dehydration due to fluid loss. Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour. This can progress to decreased urination, loss of skin color, a fast heart rate, and a decrease in responsiveness as it becomes more severe. Loose but non-watery stools in babies who are exclusively breastfed, however, are normal. What is diarrhea? How is it caused, treated and prevented? (see also script)The most common cause is an infection of the intestines due to a virus, bacterium, or parasite—a condition also known as gastroenteritis. These infections are often acquired from food or water that has been contaminated by feces, or directly from another person who is infected. The three types of diarrhea ...

Diuretic
A diuretic () is any substance that promotes diuresis, the increased production of urine. This includes forced diuresis. A diuretic tablet is sometimes colloquially called a water tablet. There are several categories of diuretics. All diuretics increase the excretion of water from the body, through the kidneys. There exist several classes of diuretic, and each works in a distinct way. Alternatively, an antidiuretic, such as vasopressin ( antidiuretic hormone), is an agent or drug which reduces the excretion of water in urine. Medical uses In medicine, diuretics are used to treat heart failure, liver cirrhosis, hypertension, influenza, water poisoning, and certain kidney diseases. Some diuretics, such as acetazolamide, help to make the urine more alkaline, and are helpful in increasing excretion of substances such as aspirin in cases of overdose or poisoning. Diuretics are sometimes abused by people with an eating disorder, especially people with bulimia nervosa, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pectin
Pectin ( ': "congealed" and "curdled") is a heteropolysaccharide, a structural polymer contained in the primary lamella, in the middle lamella, and in the cell walls of terrestrial plants. The principal chemical component of pectin is galacturonic acid (a sugar acid derived from galactose) which was isolated and described by Henri Braconnot in 1825. Commercially produced pectin is a white-to-light-brown powder, produced from citrus fruits for use as an edible gelling agent, especially in jams and jellies, dessert fillings, medications, and sweets; as a food stabiliser in fruit juices and milk drinks, and as a source of dietary fiber. Biology Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the Golgi appara ...

Day Of The Dead
The Day of the Dead () is a holiday traditionally celebrated on November 1 and 2, though other days, such as October 31 or November 6, may be included depending on the locality. The multi-day holiday involves family and friends gathering to pay respects and remember friends and family members who have died. These celebrations can take a humorous tone, as celebrants remember amusing events and anecdotes about the departed. It is widely observed in Mexico, where it largely developed, and is also observed in other places, especially by people of Mexican heritage. The observance falls during the Christian period of Allhallowtide. Some argue that there are Indigenous Mexican or ancient Aztec influences that account for the custom, though others see it as a local expression of the Allhallowtide season that was brought to the region by the Spanish; the Day of the Dead has become a way to remember those forebears of Mexican culture. The Day of the Dead is largely seen as having a festi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ponche
The term punch refers to a wide assortment of drinks, both non-alcoholic and alcoholic, generally containing fruits or fruit juice. The drink was introduced from the Indian subcontinent to England by employees of the East India Company in the late 17th century.Edwards, Graham and Sue. ''The Language of Drink'', Alan Sutton Publishing, 1988. Punch is usually served at parties in large, wide bowls, known as ''punch bowls''. In the United States, federal regulations provide the word "punch" to describe commercial beverage products that do ''not'' contain fruit or fruit juice. The term is used to label artificially flavored beverages, with or without natural flavorings, which do not contain fruit juice or concentrate in significant proportions. Thus a product labeled as "fruit punch" may contain no fruit ingredients at all. Etymology The word is commonly said to come from Hindi पाँच (''pāñch''), meaning "five", as the drink was frequently made with five ingredients: al ...

Crabapple
''Malus'' ( or ) is a genus of about 32–57 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples (sometimes known in North America as crabapples) and wild apples. The genus is native to the temperate zone of the Northern Hemisphere. Description Apple trees are typically tall at maturity, with a dense, twiggy crown. The leaves are long, alternate, simple, with a serrated margin. The flowers are borne in corymbs, and have five petals, which may be white, pink, or red, and are perfect, with usually red stamens that produce copious pollen, and a half-inferior ovary; flowering occurs in the spring after 50–80 growing degree-days, varying greatly according to subspecies and cultivar. Many apples require cross-pollination between individuals by insects (typically bees, which freely visit the flowers for both nectar and pollen); these are called self-sterile, so self-pollination is impossible, making pollin ...
