Hans Wiehler
Hans Joachim Wiehler (8 July 1930 in Klecie, Pomeranian Voivodeship, Klettendorf – 2003) was a German botanist who specialized in the plant family Gesneriaceae. In 1954 he received a Bachelor of Arts degree from Goshen College in Goshen, Indiana and a Bachelor of Divinity degree from Goshen Biblical Seminary in 1956. He married in 1958 and remained in the United States for the rest of his life. He obtained a master's degree in botany from Cornell University and in 1979 a PhD in Botany from the University of Miami. Wiehler was on the staff of the Marie Selby Botanical Gardens from 1973 until 1982, when he left Selby to found the Gesneriad Research Foundation in Sarasota, Florida. Wiehler tended to be a taxonomic "Lumpers and splitters, splitter" but many of his generic rearrangements have found acceptance: the segregation of ''Gasteranthus'' from ''Besleria'', of ''Alsobia'', ''Chrysothemis'', ''Nautilocalyx'', and ''Paradrymonia'' from ''Episcia'', and of ''Moussonia (plant), Mouss ...

Moussonia (plant)
''Moussonia'' is a genus of plants in the family Gesneriaceae. Its native range stretches from Mexico to Central America. It is found in Costa Rica, El Salvador, Guatemala, Honduras, Mexico and Panamá. Description They are herbaceous plants, or shrubs. It has an erect, branched stem, without scaly rhizomes. The leaves are arranged in the opposite way. The inflorescences are axillary, in cyme (botany), cymes or solitary flowers. The corolla (flower), corolla is red, orange or yellow, in the form of a long tube, which is broader in the centre. With the base of the extremities and narrow throat. The fruit (or seed capsule) is a dry, ovoid or ellipsoidal bivalve capsule. Taxonomy It was previously included in the genus ''Kohleria'', but with a different chromosomal number 2n=11, the ring-shaped nectary and without rhizomes. The molecular results support the separation of this genus. The genus name of ''Moussonia'' is in honour of Albert Mousson (1805–1890), a physicist and a ma ...

Polyphyletic
A polyphyletic group is an assemblage of organisms or other evolving elements that is of mixed evolutionary origin. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned more with ecology than with systema ...

Gloxinia (genus)
''Gloxinia'' is a genus containing three species of tropical rhizomatous herbs in the flowering plant family Gesneriaceae. The species are primarily found in the Andes of South America, but ''Gloxinia perennis'' is also found in Central America and the West Indies, where it has probably escaped from cultivation. ''Gloxinia perennis'' is the original (type) species of the genus, and for much of its history the genus consisted of only ''G. perennis'' and a very small number of other species. The classification of ''Gloxinia'' later changed reflect the 1976 classification of Hans Wiehler, who took a broader view of the genus. A recent analysis of ''Gloxinia'' and related genera based on molecular and morphological work has determined that Wiehler's circumscription of the genus was unnatural, both phylogenetically and morphologically. The analyses demonstrated that the genera ''Anodiscus'' and ''Koellikeria'', each with a single species, were more closely related to ''Gloxinia per ...

Taxonomic "lumping"
Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is a person who assigns examples broadly, assuming that differences are not as important as signature similarities. A "splitter" is one who makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was by Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: ''It is good to have hair-splitters & lumpers''. They were introduced more widely by George G. Simpson in his 1945 work ''The Principles of Classification and a Classification of Mammals''. As he put it: A later use can be found in the title of a 1969 paper "On lumpers and splitters ..." by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Columnea
''Columnea'' is a genus of around 200 species of epiphytic herbs and shrubs in the family Gesneriaceae, native to the tropics of the Americas and the Caribbean. The tubular or oddly shaped flowers are usually large and brightly colored – usually red, yellow, or orange – sometimes resembling a fish in shape. A common name is flying goldfish plants (see also the related ''Nematanthus'') due to the unusual flower shape. The genus was named by Carl Linnaeus after the Latinized spelling of the name of the 16th-century Italian botanist Fabio Colonna (Latin: ''Fabius Columnus''). The segregate genus '' Bucinellina'' is considered by many botanists a synonym of ''Columnea''. A full list of the species now accepted in the genus, along with their synonyms, can be found at the World Checklist of Gesneriaceae. Cultivation ''Columnea'' species grow as epiphytic plants in the wild and require bright light, good air circulation, and a well-drained growing medium that is allowed ...
