Dogbane
Dogbane, dog- bane, dog's bane, and other variations, some of them regional and some transient, are names for certain plants that are reputed to kill or repel dogs; " bane" originally meant "slayer", and was later applied to plants to indicate that they were poisonous to particular creatures. History of the term The earliest reference to such names in common English usage was in the 16th century, in which they were applied to various plants in the Apocynaceae, in particular ''Apocynum''. Some plants in the Asclepiadoideae, now a subfamily of the Apocynaceae, but until recently regarded as the separate family Asclepiadaceae, were also called dogbane even before the two families were united. It is not clear how much earlier the name had been in use in the English language, which originated about 1000 years earlier in mediaeval times. However, centuries before the appearance of the English language, Pedanius Dioscorides, in his ''De Materia Medica'', had already described members of ...

Apocynum
''Apocynum'', commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek , from "away" and "dog", referring to dogbane (''Cionura erecta''), which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe. ''Apocynum'' species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the queen butterfly. Uses '' Apocynum cannabinum'' was used as a source of fiber by Native Americans. '' Apocynum venetum'' () is used as an herbal tea in China. Dogbane contains cymarin, a cardiotonic agent formerly used to treat cardiac arrhythmia Arrhythmias, also known as cardiac arrhythmias, heart arrhythmias, or dysrhythmias, are irregularities in the Cardiac cycle, heartbeat, including when it is too fast or too slow.

Apocynaceae
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and Americas, American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found List of subfamilies and genera of Apocynaceae, here. Many species are tall trees found in tropical forests, but some grow in tropical dry (xeric) environments. Also perennial plant, perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arr ...

Plectranthus
''Plectranthus'' is a genus of about 85 species of flowering plants from the sage family, Lamiaceae, found mostly in southern and tropical Africa and Madagascar. Common names include spur-flower. ''Plectranthus'' species are herbaceous perennial plants, rarely annuals or soft-wooded shrubs, sometimes succulent; sometimes with a tuberous base. Several species are grown as ornamental plants. The cultivar = 'Plepalila' has received the Royal Horticultural Society's Award of Garden Merit. Recent phylogenetic analysis found ''Plectranthus'' to be paraphyletic with respect to '' Coleus'', ''Solenostemon'', ''Pycnostachys'' and ''Anisochilus''. The most recent treatment of the genus resurrected the genus ''Coleus'', and 212 names were changed from combinations in ''Plectranthus'', ''Pycnostachys'' and ''Anisochilus''. ''Equilabium'' was segregated from ''Plectranthus'', after phylogenetic studies supported its recognition as a phylogenetically distinct genus. Etymology The w ...

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 t ...

Ranunculaceae
Ranunculaceae (buttercup or crowfoot family; Latin "little frog", from "frog") is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide. The largest genera are '' Ranunculus'' (600 species), '' Delphinium'' (365), '' Thalictrum'' (330), '' Clematis'' (325), and '' Aconitum'' (300). Description Ranunculaceae are mostly herbaceous annuals or perennials, but some are woody climbers (such as '' Clematis'') or shrubs (e.g. '' Xanthorhiza''). Most members of the family have bisexual flowers which can be showy or inconspicuous. Flowers are solitary, but are also found aggregated in cymes, panicles, or spikes. The flowers are usually radially symmetrical but are also found to be bilaterally symmetrical in the genera '' Aconitum'' and '' Delphinium''. The sepals, petals, stamens and carpels are all generally free (not fused), the outer flower segments typically number four or five. The outer stamens may be modified to produce only nectar ...

Aconitum
''Aconitum'' (), also known as aconite, monkshood, wolf's-bane, leopard's bane, mousebane, women's bane, devil's helmet, queen of poisons, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia; growing in the moisture-retentive but well-draining soils of mountain meadows. Most ''Aconitum'' species are extremely poisonous and must be handled very carefully. Several ''Aconitum'' hybrids, such as the Arendsii form of '' Aconitum carmichaelii'', have won gardening awards—such as the Royal Horticultural Society's Award of Garden Merit. Some are used by florists. Etymology The name ''aconitum'' comes from the Greek word , which may derive from the Greek ''akon'' for dart or javelin, the tips of which were poisoned with the substance, or from ''akonae'', because of the rocky ground on w ...

Vernacular
A vernacular or vernacular language is in contrast with a "standard language". It refers to the language or dialect that is spoken by people that are inhabiting a particular country or region. The vernacular is typically the native language, normally spoken informally rather than written, and seen as of lower status than more codified forms. It may vary from more prestigious speech varieties in different ways, in that the vernacular can be a distinct stylistic register, a regional dialect, a sociolect, or an independent language. Vernacular is a term for a type of speech variety, generally used to refer to a local language or dialect, as distinct from what is seen as a standard language. The vernacular is contrasted with higher-prestige forms of language, such as national, literary, liturgical or scientific idiom, or a '' lingua franca'', used to facilitate communication across a large area. According to another definition, a vernacular is a language that has not dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Names
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is Latinized. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including such interested parti ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...
