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 ...

Durango
Durango (), officially named Estado Libre y Soberano de Durango ( en, Free and Sovereign State of Durango; Tepehuán: ''Korian''; Nahuatl: ''Tepēhuahcān''), is one of the 31 states which make up the 32 Federal Entities of Mexico, situated in the northwest of the country. With a population of 1,832,650, the 8th lowest of Mexico's states, Durango has Mexico's second-lowest population density, after Baja California Sur. The capital city, Victoria de Durango, is named after the first President of Mexico, Guadalupe Victoria. Geography General information With , Durango accounts for about 6.3% of the entire territory of Mexico. It is the fourth largest state lying at the extreme northwest of the Central Mexican Plateau, where it meets the Sierra Madre Occidental—the highest peaks in the state. The state has an average elevation of 1,775 meters above sea level, with a mean elevation of 1,750 m in the Valleys region and 2,450 m in the Sierra region. The city of Durango is on the ...

Diagnosis (taxonomy)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanical Latin
Botanical Latin is a technical language based on New Latin, used for descriptions of botanical taxa. Until 2012, International Code of Botanical Nomenclature mandated Botanical Latin to be used for the descriptions of most new taxa. It is still the only language other than English accepted for descriptions. The names of organisms governed by the Code also have forms based on Latin. Botanical Latin is primarily a written language. It includes taxon names derived from any language or even arbitrarily derived, and consequently there is no single consistent pronunciation system. When speakers of different languages use Botanical Latin in speech, they use pronunciations influenced by their own languages, or, notably in French, there may be variant spellings based on the Latin. There are at least two pronunciation systems used for Latin by English speakers. Neither system, however, works across the full spectrum of botanical names, because many non-Latin words, such as people's names, hav ...

Heterotheca
''Heterotheca'', (common names goldenasters, camphorweed, or telegraph weed) are North American plants in the family Asteraceae. Etymology ''Heterotheca'' comes from Ancient Greek "other, different" and "case, chest", and refers to the fact that, in some species in the genus, the cypselae (achenes containing seed) of the disk and ray florets have different shapes. Description, biology These are annual and perennial herbs bearing daisy-like flower heads with yellow disc florets and usually yellow ray florets, associated with mesic to xeric habitats across North America. Several species now included in ''Heterotheca'' were previously classified in the genus '' Chrysopsis'' ''Heterotheca'' species are often used as food plants by the larvae of some Lepidoptera species including '' Schinia lynx'', ''Schinia nubila'' and '' Schinia saturata'' (all of which have been recorded on ''Heterotheca subaxillaris''). Chemistry The leaf volatiles from which the name "camphorweed" is deriv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Durango
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Flora Of Mexico
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
