Tetraphyllum
''Tetraphyllum'' is a genus of flowering plants belonging to the family Gesneriaceae. , there was no consensus as to whether the correct scientific name for the genus is ''Tetraphyllum'' or ''Tetraphylloides'', some sources using the former and some the latter. Its native range is Eastern Himalaya to Indo-China. Description Species of ''Tetraphyllum'' are Perennial plant, perennial herbaceous plants. They have erect stems, which die after flowering (monocarpic). Typically the stems have what appears to be a whorl of four leaves at the very top of the stem with pairs of scale leaves lower down. The flowers are arranged in short Inflorescence#cyme, cymes. The fused petals are pink or blue, forming a wide funnel shape. There are either four or two stamens. The fruit is a capsule that splits into four valves. Taxonomy The genus name ''Tetraphyllum'' for plants in the family Gesneriaceae was first published in 1883 by Charles Baron Clarke, with the name attributed to William Griffith ...

Gesneriaceae
Gesneriaceae, the gesneriad family, is a family of flowering plants consisting of about 152 genera and ca. 3,540 species in the tropics and subtropics of the Old World (almost all Didymocarpoideae) and the New World (most Gesnerioideae), with a very small number extending to temperate areas. Many species have colorful and showy flowers and are cultivated as ornamental plants. Etymology The family name is based on the genus ''Gesneria'', which honours Swiss naturalist and humanist Conrad Gessner. Description Most species are herbaceous perennials or subshrubs but a few are woody shrubs or small trees. The phyllotaxy is usually opposite and decussate, but leaves have a spiral or alternate arrangement in some groups. As with other members of the Lamiales the flowers have a (usually) zygomorphic corolla whose petals are fused into a tube and there is no one character that separates a gesneriad from any other member of Lamiales. Gesneriads differ from related families of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Didymocarpoideae
The Didymocarpoideae are a subfamily of plants in the family Gesneriaceae. It was formerly the subfamily Cyrtandroideae. This subfamily consists mostly of tropical and subtropical Old World genera, found in Africa, Asia and the Pacific. One species (''Rhynchoglossum azureum'') is native to Central and South America. Description Didymocarpoideae is one of two main subfamilies in the Gesneriaceae, the other being Gesnerioideae. (The third subfamily, Sanangoideae, contains only the genus ''Sanango''.) Didymocarpoideae seedlings usually have cotyledons which become different in size and shape (anisocotylous). One cotyledon ceases to grow at some point and then withers away. The other continues to grow, and in extreme cases may grow to become very large and be the only leaf on the plant (''Monophyllaea'', some ''Streptocarpus''). Didymocarpoideae flowers usually have two fertile stamens, less often four and rarely one or five. The ovary is always superior. The fruit is usually a dry ...

Nomen Novum
In biological nomenclature, a ''nomen novum'' (Latin for "new name"), new replacement name (or replacement name, new substitute name, substitute name) is a scientific name that is created specifically to replace another scientific name, but only when this other name cannot be used for technical, nomenclatural reasons (for example because it is a homonym: it is spelled the same as an existing, older name). It does not apply when a name is changed for taxonomic reasons (representing a change in scientific insight). It is frequently abbreviated, ''e.g.'' ''nomen nov.'', ''nom. nov.''. Zoology In zoology establishing a new replacement name is a nomenclatural act and it must be expressly proposed to substitute a previously established and available name. Often, the older name cannot be used because another animal was described earlier with exactly the same name. For example, Lindholm discovered in 1913 that a generic name ''Jelskia'' established by Bourguignat in 1877 for a European ...

Ichnotaxon
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online database published by the Royal Botanic Gardens, Kew. It was launched in March 2017 with the ultimate aim being "to enable users to access information on all the world's known seed-bearing plants by 2020". The initial focus was on tropical African Floras, particularly Flora Zambesiaca, Flora of West Tropical Africa and Flora of Tropical East Africa. The database uses the same taxonomical source as Kew's World Checklist of Selected Plant Families, which is the International Plant Names Index, and the World Checklist of Vascular Plants (WCVP). POWO contains 1,234,000 global plant names and 367,600 images. See also *Australian Plant Name Index *Convention on Biological Diversity *World Flora Online *Tropicos Tropicos is an online botanical database containing taxonomic information on plants, mainly from the Neotropical realm (Central, and South America). It is maintained by the Missouri Botanical Garden and was established over 25 y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
