Saintpaulia
''Streptocarpus'' sect. ''Saintpaulia'' is a section within ''Streptocarpus'' subgenus ''Streptocarpella'' consisting of about ten species of herbaceous perennial flowering plants in the family Gesneriaceae, native to Tanzania and adjacent southeastern Kenya in eastern tropical Africa. The section was previously treated as a separate genus, ''Saintpaulia'', but molecular phylogenetic studies showed that it was nested within the genus ''Streptocarpus''. Species and cultivars are commonly called African violets (although they are not closely related to true violets) or saintpaulias. They are commonly sold as house plants. Several of the species and subspecies of the section are endangered, and many more are threatened, as their native cloud forest habitats are cleared for agriculture. The conservation status of ''Streptocarpus ionanthus'' has been classed as near-threatened. Description Saintpaulias, which grow from 6-15 cm tall, can be anywhere from 6-30 cm wide. The leaves ...

Streptocarpus
''Streptocarpus'' ("twisted fruit" from Greek στρεπτός (''streptos'') "twisted" and καρπός (''carpos'') "fruit") is an Afrotropical genus of flowering plants in the family Gesneriaceae. The genus is native to Afromontane biotopes from central, eastern and southern Africa, including Madagascar and the Comoro Islands. The flowers are five-petalled, salverform tubes, almost orchid-like in appearance, and hover or arch over the plant, while the pointed, elongate fruit is of a helical form similar to that of the "tusk" of a narwhal. In the wild, species can be found growing on shaded rocky hillsides or cliffs, on the ground, in rock crevices, and almost anywhere the seed can germinate and grow. For the home, there are now many hybrids of various colours and forms available. Although generally referred to simply as "Streptocarpus" or "Streps", the common name for subgenus ''Streptocarpus'' is Cape primrose, referring to the nativity of several species to South Africa ...

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] |
Walter Von Saint Paul-Illaire
Walter von Saint Paul-Illaire or Adalbert Emil Walter Le Tanneux von Saint Paul-Illaire (born January 12, 1860 in Berlin ; † December 12, 1940 ibid) was a German colonial official in East Africa. He hailed from the noble family of Le Tanneux von Saint Paul, which had moved to Prussia in the 17th century. The genus Saintpaulia of the African violet was named in his honour after he discovered it in the Usambara Mountains and had sent its seeds in 1893 to Hermann Wendland, the German botanist and Chief Royal gardener at the Herrenhausen Gardens in Hanover, who gave the plant its first description, calling it the ''Usambara veilchen'' ('Usambara violet') Life Walter von Saint Paul-Illaire, son of the naval officer and member of the Reichstag, Ulrich von Saint Paul-Illaire(1833-1902), was promoted to lieutenant in the Prussian army. His father was very interested in trees, especially firs, and corresponded with George Engelmann, the Missouri physician and botanist, about his wish ...

Violet (plant)
''Viola'' is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing between 525 and 600 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes. Some ''Viola'' species are perennial plants, some are annual plants, and a few are small shrubs. Many species, varieties and cultivars are grown in gardens for their ornamental flowers. In horticulture the term pansy is normally used for those multi-colored, large-flowered cultivars which are raised annually or biennially from seed and used extensively in bedding. The terms viola and violet are normally reserved for small-flowered annuals or perennials, including the wild species. Description Annual or perennial caulescent or acaulescent (with or without a visible plant stem above the ground) herbs, shrubs or very rarely treelets. In acaulescent taxa the foliage and flower ...

German East Africa
German East Africa (GEA; german: Deutsch-Ostafrika) was a German colony in the African Great Lakes region, which included present-day Burundi, Rwanda, the Tanzania mainland, and the Kionga Triangle, a small region later incorporated into Mozambique. GEA's area was , which was nearly three times the area of present-day Germany and double the area of metropolitan Germany at the time. The colony was organised when the German military was asked in the late 1880s to put down a revolt against the activities of the German East Africa Company. It ended with Imperial Germany's defeat in World War I. Ultimately GEA was divided between Britain, Belgium and Portugal and was reorganised as a mandate of the League of Nations. History Like other colonial powers the Germans expanded their empire in the Africa Great Lakes region, ostensibly to fight slavery and the slave trade. Unlike other imperial powers, however they never formally abolished either slavery or the slave trade and preferre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Violaceae
Violaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus ''Viola'', the violets and pansies. Older classifications such as the Cronquist system placed the Violaceae in an order named after it, the Violales or the Parietales. However, molecular phylogeny studies place the family in the Malpighiales as reflected in the Angiosperm Phylogeny Group (APG) classification, with 41 other families, where it is situated in the parietal clade of 11 families. Most of the species are found in three large genera, ''Viola'', ''Rinorea'' and ''Hybanthus''. The other genera are largely monotypic or oligotypic. The genera are grouped into four clades within the family. The species are largely tropical or subtropical but ''Viola'' has a number of species in temperate regions. Many genera have a very restricted distribution. Description Though the best-known genus, ''Viola'', is herbaceous, most species are ...
