Entada Elephantina
''Entada elephantina'', commonly known as the eland's wattle or elephant's root, is a subshrub in the mimosoid clade of legumes. They occur widely and in several bioregions of southern Africa in Namibia, Botswana, Zimbabwe, Mozambique, South Africa, Eswatini, and Lesotho. Considerable size variation has been noted, and polyploidy Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one fro ... was suspected. Description They have a suffrutescent habit typical of their genus. They produce unbranched and unarmed aerial stems of less than a metre tall. The various populations show considerable variation in terms of the number of pinnae pairs and the number, size and shape of the leaflets. They flower from September to November and are pollinated mainly by the African honeybee. The flowering racem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William John Burchell
__NOTOC__ William John Burchell (23 July 1781 – 23 March 1863) was an English explorer, naturalist, traveller, artist, and author. His thousands of plant specimens, as well as field journals from his South African expedition, are held by Kew Gardens, and his insect collection by the Oxford University Museum. Early life and education William John Burchell was born in Fulham, London, the son of Matthew Burchell, botanist and owner of Fulham Nursery, and his wife. His father owned nine and a half acres of land adjacent to the gardens of Fulham Palace. Burchell served a botanical apprenticeship at Kew and was elected F.L.S. (Fellow of the Linnaen Society) in 1803. At about this time, he became enamoured of Lucia Green of Fulham, but faced strong disapproval from his parents when he broached the idea of an engagement. Career On 7 August 1805, Burchell at the age of 24 sailed for St. Helena aboard the East Indiaman intending to set up there as a merchant with a partner from Lo ...

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Subshrub
A subshrub (Latin ''suffrutex'') or undershrub is either a small shrub (e.g. prostrate shrubs) or a perennial that is largely herbaceous but slightly woody at the base (e.g. garden pink and florist's chrysanthemum). The term is often interchangeable with "bush".Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 Because the criteria are matters of degree (normally of height) rather than of kind, the definition of a subshrub is not sharply distinguishable from that of a shrub; examples of reasons for describing plants as subshrubs include ground-hugging stems or low growth habit. Subshrubs may be largely herbaceous though still classified as woody, with overwintering perennial woody growth much lower-growing than deciduous summer growth. Some plants described as subshrubs are only weakly woody and some persist for only a few years. Others, such as '' Oldenburgia paradoxa'' live indefin ...

Mimosoideae
The Mimosoideae are a traditional subfamily of trees, herbs, lianas, and shrubs in the pea family (Fabaceae) that mostly grow in tropical and subtropical climates. They are typically characterized by having radially symmetric flowers, with petals that are twice divided (valvate) in bud and with numerous showy, prominent stamens. Recent work on phylogenetic relationships has found that the Mimosoideae form a clade nested with subfamily Caesalpinioideae and the most recent classification by ''The Legume Phylogeny Working Group'' refer to them as the Mimosoid clade within subfamily Caesalpinioideae. The group includes about 40 genera and 2,500 species. Taxonomy Some classification systems, for example the Cronquist system, treat the Fabaceae in a narrow sense, raising the Mimisoideae to the rank of family as Mimosaceae. The Angiosperm Phylogeny Group treats Fabaceae in the broad sense. The Mimosoideae were historically subdivided into four tribes (Acacieae, Ingeae, Mimoseae, and ...

Legume
Legumes are plants in the pea family Fabaceae (or Leguminosae), or the fruit or seeds of such plants. When used as a dry grain for human consumption, the seeds are also called pulses. Legumes are grown agriculturally, primarily for human consumption, but also as livestock forage and silage, and as soil-enhancing green manure. Legumes produce a botanically unique type of fruit – a simple fruit, simple Dry fruits, dry fruit that develops from a simple carpel and usually Dehiscence (botany) , dehisces (opens along a seam) on two sides. Most legumes have Symbiosis , symbiotic nitrogen fixation , nitrogen-fixing bacteria, Rhizobia, in structures called root nodules. Some of the fixed nitrogen becomes available to later crops, so legumes play a key role in crop rotation. Terminology The term ''pulse'', as used by the United Nations' Food and Agriculture Organization (FAO), is reserved for legume crops harvested solely for the dry seed. This excludes green beans and Pea , green ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyploidy
Polyploidy is a condition in which the cells of an organism have more than two paired sets of ( homologous) chromosomes. Most species whose cells have nuclei (eukaryotes) are diploid, meaning they have two complete sets of chromosomes, one from each of two parents; each set contains the same number of chromosomes, and the chromosomes are joined in pairs of homologous chromosomes. However, some organisms are polyploid. Polyploidy is especially common in plants. Most eukaryotes have diploid somatic cells, but produce haploid gametes (eggs and sperm) by meiosis. A monoploid has only one set of chromosomes, and the term is usually only applied to cells or organisms that are normally diploid. Males of bees and other Hymenoptera, for example, are monoploid. Unlike animals, plants and multicellular algae have life cycles with two alternating multicellular generations. The gametophyte generation is haploid, and produces gametes by mitosis; the sporophyte generation is diploid and p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
African 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 result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is native to southern Africa, in Mozambique, Zimbabwe, Botswana, and the Northern Provinces of South Africa. It grows on rocky slopes or ridges, in either woodland, grassland or scrubland. The species is named after the botanist Joseph Burke. Description The shrub or small tree has a dense rounded crown, and usually reaches between 1 and 3 metres in height. The grey bark turns brown and eventually blackish as the tree ages. The bipinnately compound leaves measure some 25 cm long, and bear 4 to 8 pinnae with 12 to 23 pairs of leaflets each. Their fr ...

Entada
''Entada'' is a genus of flowering plants in the family Fabaceae, in the mimosoid clade of the subfamily Caesalpinioideae. It consists of some 30 species of trees, shrubs and tropical lianas. About 21 species are known from Africa, six from Asia, two from the American tropics and one with a pantropical distribution. They have compound leaves and produce exceptionally large seedpods of up to long. Their seeds are buoyant and survive lengthy journeys via rivers and ocean currents, to eventually wash up on tropical beaches. According to Menninger the liana species of ''Entada'' can grow up to longer in eighteen months. According to Dr. Bruno Kremer of the University of Cologne, ''Entada'' spp. "beats all records for longitudinal growth" reaching lengths "between ". Species 40 species are accepted. * '' Entada abyssinica'' Steud. ex A.Rich. * ''Entada africana'' Guill. & Perr. * '' Entada arenaria'' Schinz * '' Entada bacillaris'' F.White * '' Entada borneensis'' Ridl. * '' Ent ...

Flora Of Namibia
The wildlife of Namibia is composed of its flora and fauna. Namibia's endangered species include the wild dog, black rhino, oribi and puku. Endangered species Namibia has many endangered species within its national parks and wildlife resorts. The puku antelope is limited to about 100 individuals along the Chobe River in Botswana and the Linyati marshes in Namibia. The black rhino and white rhino have suffered the most from poaching and are on the verge of extinction. If there had been no effort to save them in the last 20 years they most likely would have disappeared. While both species occur naturally in Namibia, in many of the reserves they have been reintroduced. The country also has the largest population in southern Africa of cheetahs not contained within national parks. There are over twenty species of antelope ranging from the largest, the eland, to the smallest, the Damara dik-dik. The gemsbok, a striking antelope with long symmetrical horns and distinctiv ...

Endangered Plants
In September 2016, the International Union for Conservation of Nature (IUCN) listed 3654 endangered plant species. Of all evaluated plant species, 17% are listed as endangered. The IUCN also lists 99 subspecies and 101 varieties as endangered. No subpopulations of plants have been evaluated by the IUCN. For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered plants are listed separately. There are 6147 plant species which are endangered or critically endangered. Additionally 1674 plant species (7.6% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
