Dyssodia Papposa
''Dyssodia papposa'' is a species of annual herbaceous forb in the genus '' Dyssodia'', commonly known as fetid marigold or prairie dogweed. It is native to North America and parts of the Southwest, extending into the Northeast. The plant has been used by Native Americans to treat multiple medical conditions. Description Fetid marigold is a erect multi-branching annual with a large taproot, common to anthropogenically disturbed areas such as roadsides, fields, and meadows, at elevations from 3000–6500 ft (914–1981 m). Its height is 4–16 inches (5–70 cm). The leaves are simple and opposite, 3/4 in to 2 in (15–50 mm) long and linearly lobate. The flowers have the disk and ray structure characteristic of the Asteraceae family; both are yellow-orange, up to 1/2in long with 5–8 ray flowers which are up to 3.5cm long and 1.5 cm wide, with tubular disk flowers and greenish outer and inner bracts. Seeds are small, hairy, narrowly conical with a tuft of bristle at the top, dar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Étienne Pierre Ventenat
Étienne Pierre Ventenat (1 March 1757 – 13 August 1808) was a French botanist born in Limoges. He was the brother of naturalist Louis Ventenat (1765–1794). While employed as director of the ecclesiastic library Sainte-Geneviève in Paris, Ventenat took a trip to England. Here he investigated the country's botanical gardens, inspiring him to pursue a vocation in sciences. Following his time at library he became an active botanist, studying under and collaborating with botanist Charles Louis L'Héritier de Brutelle (1746–1800). In 1795 he was elected a member of the ''Institut national des sciences et des arts'', later known as the ''Académie des sciences''. In 1794 he wrote a treatise on the principles of botany titled ''Principes de botanique, expliqués au Lycée républicain par Ventenat''. After publication he became so disappointed with its mediocrity that he reportedly made efforts to procure all copies of the book and have them destroyed. In 1798 he published a Fren ...

Forb
A forb or phorb is an herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in biology and in vegetation ecology, especially in relation to grasslands and understory. Typically these are dicots without woody stems. Etymology The word "forb" is derived from Greek ''phorbḗ'' (), meaning "pasture" or "fodder". The Hellenic spelling "phorb" is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth form. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dyssodia
''Dyssodia''is a small genus of flowering plants in the family Asteraceae. Many species formerly included in ''Dyssodia'' are now treated as members of other related genera, including '' Thymophylla'' or ''Adenophyllum''. ''Dyssodia papposa'' is usually retained in this genus. The name is derived from the Greek δυσοδια (''dusodia''), meaning "ill-smelling". Several species of ''Dyssodia'' (sensu lato) have found their way into the nursery trade and are relatively popular flowering annuals for hot, dry sites. Generally sold as threadleaf dyssodia (''Dyssodia tenuisecta'') and golden dyssodia (''Dyssodia'' cf. ''pentachaeta''). They perform best in well-drained soil. Phytochemistry Two species of the genus, ''D. acerosa'' and ''D. pentachaeta'' have been studied for their essential oil content. Selected species *'' Dyssodia decipiens'' (Bartl.) M.C.Johnst. ex M.C.Johnst. & B.L.Turner *'' Dyssodia greggii'' (A.Gray) B.L.Rob. *'' Dyssodia montana'' (Benth.) A.Gray *''Dys ...

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nathalis Iole
''Nathalis iole'', the dainty sulphur or dwarf yellow, is a North American butterfly in the family Pieridae. Description This species is the smallest North American pierid. A rare population, known from Homestead (Smith et al., 1994), is said to have mostly white individuals. Some feel that the dainty sulphur is so unique among pierids, in shape and in several structural features, that it should belong in a separate subfamily. Its appearance is highly variable but a subset of distinctive features aid in identification. The forewings' elongated shape is distinctive. The upperside of the wings is yellow with the tip of the forewing being black. Black bars extend along the trailing edge of the forewing and the leading edge of the hindwing. Male dainty sulphurs have an oval scent patch (called an androconial spot) in each hindwing bar. The androconial spot is reddish orange but fades to pale yellow after death. The underside of the wings varies depending on the season. Sum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Dog
Prairie dogs (genus ''Cynomys'') are herbivorous burrowing ground squirrels native to the grasslands of North America. Within the genus are five species: black-tailed, white-tailed, Gunnison's, Utah, and Mexican prairie dogs. In Mexico, prairie dogs are found primarily in the northern states, which lie at the southern end of the Great Plains: northeastern Sonora, north and northeastern Chihuahua, northern Coahuila, northern Nuevo León, and northern Tamaulipas. In the United States, they range primarily to the west of the Mississippi River, though they have also been introduced in a few eastern locales. They are also found in the Canadian Prairies. Despite the name, they are not actually canines; prairie dogs, along with the marmots, chipmunks, and several other basal genera belong to the ground squirrels (tribe ''Marmotini''), part of the larger squirrel family (''Sciuridae''). Prairie dogs are considered a keystone species with their mounds often being used by other s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dakota People
The Dakota (pronounced , Dakota language: ''Dakȟóta/Dakhóta'') are a Native American tribe and First Nations band government in North America. They compose two of the three main subcultures of the Sioux people, and are typically divided into the Eastern Dakota and the Western Dakota. The four bands of Eastern Dakota are the Bdewákaŋthuŋwaŋ, Waȟpéthuŋwaŋ, Waȟpékhute, and Sisíthuŋwaŋ and are sometimes referred to as the Santee (''Isáŋyathi'' or ''Isáŋ-athi''; "knife" + "encampment", "dwells at the place of knife flint"), who reside in the eastern Dakotas, central Minnesota and northern Iowa. They have federally recognized tribes established in several places. The Western Dakota are the Yankton, and the Yanktonai (''Iháŋktȟuŋwaŋ'' and ''Iháŋktȟuŋwaŋna''; "Village-at-the-end" and "Little village-at-the-end"), who reside in the Upper Missouri River area. The Yankton-Yanktonai are collectively also referred to by the endonym ''Wičhíyena'' ("Those Who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipyretic
An antipyretic (, from ''anti-'' 'against' and ' 'feverish') is a substance that reduces fever. Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, which results in a reduction in fever. Most antipyretic medications have other purposes. The most common antipyretics in the US are usually ibuprofen and aspirin, which are nonsteroidal anti-inflammatory drugs (NSAIDs) used primarily as anti-inflammatories and analgesics (pain relievers), but which also have antipyretic properties; and paracetamol (acetaminophen), an analgesic without anti-inflammatory properties. There is some debate over the appropriate use of such medications, since fever is part of the body's immune response to infection. A study published by the Royal Society claims that fever suppression causes at least 1% more influenza deaths in the United States, or 700 extra deaths per year.
