Seemannia is a New World genus in the flowering plant family Gesneriaceae. The New World is one of the names used for the non-Eurasian/non-African parts of the Earth specifically the Americas and Australia. The flowering plants or angiosperms ( Angiospermae or Magnoliophyta) are the most widespread group Gesneriaceae is a family of Flowering plants consisting of ca There are four species in the genus, primarily found in the Andean regions of South America. The Andes form the world's longest exposed Mountain range. They lie as a continuous chain of highland along the western coast of South America. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The name honors the German botanist Berthold Carl Seemann. Berthold Carl Seemann 25 February 1825 Hanover, Germany - 10 October 1871 Nicaragua, Central America was a German Botanist.
Taxonomic history
Seemannia was created in 1855 by Regel for the species Seemannia ternifolia (now considered a synonym of S. sylvatica). In 1976 Seemannia was synonymized under the genus Gloxinia by gesneriad specialist Hans Wiehler but has more recently been revived following phylogenetic and morphological research on relationships of Gloxinia and related genera, which suggested that Wiehler's generic concept of Gloxinia was overly broad and polyphyletic. Hans Joachim Wiehler (1930-2003 was a Prussian-born American botanist who specialized in the plant family Gesneriaceae. In Phylogenetics, a Taxon is polyphyletic ( Greek for "of many races" if the trait its members have in common evolved separately in different Although now recognized as a separate genus, Seemannia is closely related to Gloxinia and hybrids between the two genera are fertile although the two genera are very distinct morphologically. In Biology, hybrid has two meanings The first meaning is the result of interbreeding between two animals or plants of different taxa.
Although all of the species occur in the Andes, Seemannia purpurascens is unusual in having a disjunct distribution, with populations in northern South America (Guyana, French Guiana, and northern Brazil) widely separated from Andean populations in southern Peru and Bolivia. The Andes form the world's longest exposed Mountain range. They lie as a continuous chain of highland along the western coast of South America. In biology a Taxon with a disjunct distribution is one that has two or more groups that are related but widely separated from each other geographically South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a Guyana (ɡaɪˈænə or /ɡiːˈɑːnə/ officially the Co-operative Republic of Guyana and previously known as British Guiana, is the only Nation state French Guiana (Guyane française officially fr ''Guyane'' is an Overseas department (French département d'outre-mer, or DOM) of France |utc_offset = -2 to -4 |time_zone_DST = BRST |utc_offset_DST = -2 to -5 |cctld Peru (Perú Piruw Piruw officially the Republic of Peru ( reˈpuβlika del peˈɾu is a country in western South America.
