Umtiza Listeriana
''Umtiza'' is a monotypic genus in the legume family Fabaceae containing the single species ''Umtiza listeriana''. This tree is endemic to a small coastal portion of the Eastern Cape in South Africa. Distribution ''Umtiza listeriana'' is found from East London to Kentani and King William's Town, with an EOO of at 6 known locations. Conservation In 2020, an area of surrounding the Umtiza Nature Reserve (one of the last refuges of ''Umtiza'') was declared a Controlled Forest Area to further protect and rehabilitate the remaining Umtiza Forest. ''Umtiza listeriana'' is threatened by the expansion of illegal settlements near the Umtiza Forest, leading to deforestation and harvesting for traditional medicine. For these reasons SANBI has given it the conservation classification: Vulnerable B1ab(v).

Pretoria National Botanical Garden
The Pretoria National Botanical Garden is one of South Africa's nine National Botanical Gardens. The garden is wedged between Pretoria Road and Cussonia Avenue in Brummeria, in eastern Pretoria, Gauteng, and flanks a central rocky ridge that runs from east to west. The garden was established in 1946, and of late hosts the headquarters of the South African National Biodiversity Institute. History The Garden was initially known as the 'Pretoria National Botanic Garden' and opened in June 1946 when the University of Pretoria granted approval from the Department of Agriculture for the development of a botanical garden on a piece of land that was previously part of the University’s Experimental Farm. The farm had to be abandoned due the presence of poison leaf (''Dichapetalum cymosum''), a plant which is poisonous to livestock. The Garden was officially opened on 23 October 1958, but it could only be visited by special arrangement because it was primarily a research facility under ...

Umtiza Nature Reserve
The Umtiza Nature Reserve is one of two forest nature reserves in the greater East London Coast Nature Reserve. It is named after '' Umtiza listeriana'', a rare and protected legume found within the reserve. The Buffalo River borders the northern part of the reserve, and includes the remaining Umtiza Forest on the southern banks of the river. The Buffalo Pass traverses the entirety of the reserve and the surrounding Controlled Forest Area. History The Fort Grey State forest which is found south of the current reserve, was proclaimed a protected forest prior to the Union of South Africa. In 2020, an area of surrounding the reserve, which include the Grey Dell and Fort Grey forest areas, and private farmland, were declared a Controlled Forest Area to prevent deforestation and rehabilitate the remaining Umtiza Forest. Biodiversity A variety of wildlife is found within the reserve. Birds There are 30-40 bird species in the reserve, including: * African dusky flycatcher ...

Monotypic Fabaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, ''Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.'' ...

Caesalpinioideae
Caesalpinioideae is a botanical name at the rank of subfamily, placed in the large family Fabaceae or Leguminosae. Its name is formed from the generic name ''Caesalpinia''. It is known also as the peacock flower subfamily. The Caesalpinioideae are mainly trees distributed in the moist tropics, but include such temperate species as the honeylocust (''Gleditsia triacanthos'') and Kentucky coffeetree (''Gymnocladus dioicus''). It has the following clade-based definition: The most inclusive crown clade containing '' Arcoa gonavensis'' Urb. and ''Mimosa pudica'' L., but not '' Bobgunnia fistuloides'' (Harms) J. H. Kirkbr. & Wiersema, '' Duparquetia orchidacea'' Baill., or '' Poeppigia procera'' C.Presl In some classifications, for example the Cronquist system, the group is recognized at the rank of family, Caesalpiniaceae. Characteristics * Specialised extrafloral nectaries often present on the petiole and / or on the primary and secondary rachises, usually between pinnae or ...

Dehiscence (botany)
Dehiscence is the splitting of a mature plant structure along a built-in line of weakness to release its contents. This is common among fruits, anthers and sporangia. Sometimes this involves the complete detachment of a part; structures that open in this way are said to be dehiscent. Structures that do not open in this way are called indehiscent, and rely on other mechanisms such as decay or predation to release the contents. A similar process to dehiscence occurs in some flower buds (e.g., ''Platycodon'', ''Fuchsia''), but this is rarely referred to as dehiscence unless wikt:circumscissile, circumscissile dehiscence is involved; anthesis is the usual term for the opening of flowers. Dehiscence may or may not involve the loss of a structure through the process of abscission. The lost structures are said to be wikt:caducous, caducous. Association with crop breeding Manipulation of dehiscence can improve crop yield since a Trait (biological), trait that causes seed dispersal i ...

East African Lowland Honey Bee
The East African lowland honey bee (''Apis mellifera scutellata'') is a subspecies of the western honey bee. It is native to central, southern and eastern Africa, though at the southern extreme it is replaced by the Cape honey bee (''Apis mellifera capensis''). This subspecies has been determined to constitute one part of the ancestry of the Africanized bees (also known as "killer bees") spreading through North and South America. The introduction of the Cape honey bee into northern South Africa poses a threat to East African lowland honey bees. If a female worker from a Cape honey bee colony enters an East African lowland honey bee nest, she is not attacked, partly due to her resemblance to the East African lowland honey bee queen. As she is capable of parthenogenetic reproduction, she may begin laying eggs which hatch as "clones" of herself, which will also lay eggs, causing the parasitic ''A. m. capensis'' workers to increase in number. The death of the host colony results from ... [...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] |
Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...
