Oxalis Tenuifolia
''Oxalis tenuifolia'', also known by its common name thinleaf sorrel, is a species from the genus ''Oxalis''. The plant was first described by Christian Friedrich Ecklon and Karl Ludwig Philipp Zeyher Karl Ludwig Philipp Zeyher (2 August 1799 Dillenburg, Hessen, Holy Roman Empire – 13 December 1858 Cape Town), was a botanical and insect collector who collected extensively in Cape Colony.

Species
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. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists 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. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Oxalis
''Oxalis'' ( (British English) or (American English)) is a large genus of flowering plants in the wood-sorrel family, Oxalidaceae, comprising over 550 species. The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico, and South Africa. Many of the species are known as wood-sorrels (also as wood sorrels or woodsorrels) as they have an acidic taste reminiscent of the sorrel proper (''Rumex acetosa''), which is not closely related. Some species are called yellow sorrels or pink sorrels after the colour of their flowers instead. Other species are colloquially known as false shamrocks, and some called sourgrasses. For the genus as a whole, the term oxalises is also used. Description The plants are annual or perennial. The leaves are divided into three to ten or more obovate and top-notched leaflets, arranged palmately with all the leaflets of roughly equal size. The majority of species have three ...

Christian Friedrich Ecklon
Christian Friedrich Ecklon (17 December 1795 – 1 December 1868) was a Denmark, Danish botany, botanical collector and apothecary. Ecklon is especially known for being an avid collector and researcher of plants in South Africa. Biography Ecklon was from Åbenrå, Denmark. He was trained as a pharmacist in Kiel. He first went to South Africa in 1823. During his visit he worked as an apothecary whilst also looking for plants with medicinal value. A shortage of funds and deteriorating health forced him to live in poor circumstances. When he returned to Europe in 1828, he had collected an extensive herbarium and published first specimens of his voyages as an exsiccata in cooperation with Unio Itineraria, a Württemberg Botanical Society which had been organized by botanist Christian Ferdinand Friedrich Hochstetter (1787–1860) and physician Ernst Gottlieb von Steudel (1783–1856). During his stay in Hamburg from 1833 to 1838, he worked on revising his collection. This herbarium wou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Ludwig Philipp Zeyher
Karl Ludwig Philipp Zeyher (2 August 1799 Dillenburg, Hessen, Holy Roman Empire – 13 December 1858 Cape Town), was a botanical and insect collector who collected extensively in Cape Colony. He was the author, with Christian Friedrich Ecklon, of ''Enumeratio Plantarum Africae Australis'' (1835-7), a descriptive catalogue of South African plants. In 1816 Zeyher was apprenticed to his uncle Johann Michael Zeyher who was head gardener at the ducal gardens of Schwetzingen. Here he met Franz Sieber and was talked into a partnership with the aim of collecting and selling natural history specimens - a burgeoning industry in the 19th century. They sailed for Mauritius in August 1822, however Zeyher was left at the Cape while Sieber went on to Mauritius and Australia. On his return in April 1824, Sieber picked up the specimens collected by Zeyher, assuring him of payment in due course. Sieber distributed a number of these specimens in his exsiccata named ''Flora Capensis''. No payment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
