Felicia Cana
''Felicia cana'' is a low and slender shrublet of up to high, covered in white felty hairs, that is assigned to the family Asteraceae. It has alternately arranged leaves, and flower heads of about across, with 3–4 whorls of involucral bracts, and about 20 blue purple ray florets, surrounding many yellow disc florets in the centre. Very characteristic for the species are also the middle-long hairs with forked tips on the surface of its fruits. It is an endemic species that is restricted to a zone along the southern coast of the Western Cape province of South Africa. Description ''Felicia cana'' is an upright, richly branched shrub of up to high. All parts except for the florets are covered in dense white felty hairs. The leaves are arranged alternately, are succulent, inverted lance-shaped in outline, up to 1 cm (0.6 in) long and 1 mm (0.06 in) wide, set at an oblique upward angle. The flower heads sit individually at the tip of an inflorescence st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Pappus (botany)
In Asteraceae, the pappus is the modified calyx, the part of an individual floret, that surrounds the base of the corolla tube in flower. It functions as a wind-dispersal mechanism for the seeds. The term is sometimes used for similar structures in other plant families e.g. in certain genera of the Apocynaceae, although the pappus in Apocynaceae is not derived from the calyx of the flower. In Asteraceae, the pappus may be composed of bristles (sometimes feathery), awns, scales, or may be absent, and in some species, is too small to see without magnification. In genera such as ''Taraxacum'' or ''Eupatorium'', feathery bristles of the pappus function as a "parachute" which enables the seed to be carried by the wind. The name derives from the Ancient Greek word ''pappos'', Latin ''pappus'', meaning "old man", so used for a plant (assumed to be an ''Erigeron'' species) having bristles and also for the woolly, hairy seed of certain plants. The pappus of the dandelion plays a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felicia (plant)
''Felicia'' is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy family (Compositae or Asteraceae). Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of, in this case between two and four whorls of, bracts. In ''Felicia'', the centre of the head is taken by yellow, seldom whitish or blackish blue disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white or yellow ligulate florets and rarely ligulate florets are absent. These florets sit on a common base (or receptacle) and are not individually subtended by a bract (or palea). Most species occur in the Cape Floristic Region, which is most probably the area where the genus originates and had most of its development. Some species can be found in the eastern half of Africa up to Sudan and the south-western Arabian pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African National Biodiversity Institute
The South African National Biodiversity Institute (SANBI) is an organisation established in 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004, under the South African Department of Environmental Affairs (later named Department of Environment, Forestry and Fisheries), tasked with research and dissemination of information on biodiversity, and legally mandated to contribute to the management of the country’s biodiversity resources. History SANBI was established on 1 September 2004 in terms of the National Environmental Management: Biodiversity Act, No 10 of 2004. Previously, in 1989, the autonomous statutory National Botanical Institute (NBI) had been formed from the National Botanic Gardens and the Botanical Research Institute, which had been founded in the early 20th century to study and conserve the South African flora. The mandate of the National Botanical Institute was expanded by the act to include the full diversity of the South Af ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Least Concern Species
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...

William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California.

Swellendam
Swellendam is the fifth oldest town in South Africa (after Cape Town, Stellenbosch, Simon's Town, and Paarl), a town with 17,537 inhabitants situated in the Western Cape province. The town has over 50 provincial heritage sites, most of them buildings of Cape Dutch architecture. Swellendam is situated on the N2, approximately 220 km from both Cape Town and George. History Early travellers and explorers who visited the Cape in the 16th century traded with the Khoikhoi people who lived on these shores and in the interior. When the Dutch East India Company established a replenishment station at the Cape in 1652, trade continued inland as far as Swellendam. In 1743 Swellendam was declared a magisterial district, the third-oldest in South Africa, and was named after Governor Hendrik Swellengrebel, the first South African born Governor, and his wife, Helena Ten Damme. This outlying settlement soon became a gateway to the interior, and was visited by many famous explorers an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 while also looking for plants with medicinal value. Lack of funding and a deteriorating health forced him to live in poor circumstances. When he returned to Europe in 1828, he had collected an extensive herbarium. During his stay in Hamburg from 1833 to 1838, he worked on revising this collection. This herbarium would become the basis for the ''Flora Capensis'' (1860–1865) by his friend, Hamburg botanist Otto Wilhelm Sonder (1812–1881) in collaboration with the Irish botanist William Henry Harvey (1811–1866). The herbarium was later sold to Unio Itineraria, a Württemberg Botanical Soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
