Patrick Browne (physician)
Patrick Browne (1720–1790) was an Irish physician and botanist. Career Browne was born in Woodstock, County Mayo in 1720, sent to relatives on Antigua in 1737 and returned to Europe due to ill health after two years. He studied medicine, natural history and especially botany at Reims, Paris, and Leyden, qualifying in 1743. He worked as a physician at St. Thomas's Hospital, London, visited Barbados, Montserrat, Antigua, and St. Kitts in the West Indies and settled as physician in Jamaica in 1746. He corresponded with the botanist Carl Linnaeus, among whose papers were found fragments of articles on venereal diseases and yaws by Browne. His major work, ''The Civil and Natural History of Jamaica'' (1756), illustrated by the botanic artist Georg Dionysius Ehret, contains new names for 104 genera.Patrick Browne author, 1756 - Climatoloy, Medical - 503 pages He retired to Rushbrook, near Claremorris, County Mayo County Mayo (; ) is a Counties of Ireland, county in Repu ...

Metopium Brownei
''Metopium brownei'' (also known as chechem, chechen, or black poisonwood) is a species of plant in the family Anacardiaceae. Distribution and habitat It is found in Hispaniola (the Dominican Republic and Haiti), Cuba, Jamaica, northern Guatemala, Belize, and from the Yucatán to Veracruz in Mexico. Description Like its cousin, ''Metopium toxiferum'', it produces urushiol in its bark, which can cause contact dermatitis; therefore, live trees and fresh cut logs should be handled carefully. The wood of this tree is a valuable source of lumber in Central America and the West Indies The West Indies is an island subregion of the Americas, surrounded by the Atlantic Ocean, North Atlantic Ocean and the Caribbean Sea, which comprises 13 independent island country, island countries and 19 dependent territory, dependencies in thr ....

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] |
Sumac
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 ...

Anacardiaceae
The Anacardiaceae, commonly known as the cashew family or sumac family, are a family of flowering plants, including about 83 genera with about 860 known species. Members of the Anacardiaceae bear fruits that are drupes and in some cases produce urushiol, an irritant. The Anacardiaceae include numerous genera, several of which are economically important, notably cashew (in the type genus '' Anacardium''), mango, Chinese lacquer tree, yellow mombin, Peruvian pepper, poison ivy, poison oak, sumac, smoke tree, marula and cuachalalate. The genus '' Pistacia'' (which includes the pistachio and mastic tree) is now included, but was previously placed in its own family, the Pistaciaceae. The cashew family is more abundant in warm or tropical regions with only a few species living in the temperate zones. Mostly native to tropical Americas, Africa and India. '' Pistacia'' and some species of '' Rhus'' can be found in southern Europe, '' Rhus'' species can be found in much of N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dioecious
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Contact Dermatitis
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable. Contact dermatitis results from either exposure to allergens ( allergic contact dermatitis), or irritants ( irritant contact dermatitis). Allergic contact dermatitis involves a delayed type of hypersensitivity and previous exposure to an allergen to produce a reaction. Irritant contact dermatitis is the most common type and represents 80% of all cases. It is caused by prolonged exposure to irritants, leading to direct injury of the epidermal cells of the skin, which activates an immune response, resulting in an inflammatory cutaneous reaction. Phototoxic dermatitis occurs when the allergen or irritant is activated by sunlight. Diagnosis of allergic contact dermati ...
