Senegalia Hereroensis
''Senegalia hereroensis'' is a species of trees in the genus ''Senegalia''. It is indigenous to Southern Africa, and its native range includes western Zimbabwe, Botswana, and Namibia, and the Northern Provinces, Cape Provinces, and Free State of South Africa. It is native to Zambezian wooded grassland (savanna), and wooded grasslands of the Kalahari-Highveld regional transition zone. ''Senegalia hereroensis'' may be confused with ''Senegalia caffra ''Senegalia caffra'', also known as hook-thorn or ''Acacia caffra'', is a tree that occurs commonly in southern Africa.

Adolf Engler
Heinrich Gustav Adolf Engler (25 March 1844 – 10 October 1930) was a German botanist. He is notable for his work on alpha taxonomy, plant taxonomy and phytogeography, such as ''Die natürlichen Pflanzenfamilien'' (''The Natural Plant Families''), edited with Karl Anton Eugen Prantl, Karl A. E. von Prantl. Even now, his system of plant classification, the Engler system, is still used by many Herbarium, herbaria and is followed by writers of many manuals and Flora (plants), floras. It is still the only system that treats all 'plants' (in the wider sense, algae to flowering plants) in such depth. Engler published a prodigious number of taxonomic works. He used various artists to illustrate his books, notably Joseph Pohl (1864–1939), an illustrator who had served an apprenticeship as a wood-engraver. Pohl's skill drew Engler's attention, starting a collaboration of some 40 years. Pohl produced more than 33 000 drawings in 6 000 plates for ''Die naturlichen Pflanzenfamilien''. He ...

Senegalia
''Senegalia'' (from Senegal and ''Acacia senegal'' (L.) Willd.) is a genus of flowering plants in the family Fabaceae. It belongs to the Mimosoid clade. Until 2005, its species were considered members of ''Acacia.'' The genus was considered polyphyletic and required further division, with the genera '' Parasenegalia'' and ''Pseudosenegalia'' accepted soon after. ''Senegalia'' can be distinguished from other acacias by its spicate inflorescences and non-spinescent stipules. Plants in the genus are native to the tropical and subtropical areas of the world, occurring on the Australian, Asian, African and South and North American continents, as well as in Wallacea. Species list ''Senegalia'' comprises the following 222 species, as of February 2021: *'' Senegalia adenocalyx'' *''Senegalia albizioides'' — climbing wattle *'' Senegalia alemquerensis'' *'' Senegalia alexae'' *''Senegalia altiscandens'' *'' Senegalia amazonica'' *''Senegalia andamanica'' *'' Senegalia angust ...

List Of Southern African Indigenous Trees And Woody Lianes
This is a list of Southern African trees, shrubs, suffrutices, geoxyles and lianes, and is intended to cover Angola, Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia and Zimbabwe. The notion of 'indigenous' is of necessity a blurred concept, and is clearly a function of both time and political boundaries. The global distribution of plants useful to humans, or inadvertently transported by them, is closely linked to a mapping of their journeys and settlements, and the movement of species in prehistoric times must be inferred from archaeological and palaeontological remains, centers of diversity, DNA and other sources.

Senegalia Caffra
''Senegalia caffra'', also known as hook-thorn or ''Acacia caffra'', is a tree that occurs commonly in southern Africa. Though it is cultivated, it often occurs naturally in Gauteng suburban gardens, together with '' Acacia karroo'' and ''Acacia robusta''. It is up to tall and may be found in open woodland, grassland, rocky hillsides or watercourses. Description It has extremely hard, dense and attractive timber, and is only spared from intense exploitation because of its strongly twisted trunk which does not lend itself to long planks, and its tendency to develop heart rot. The bark is rough, dark grey and flaking, while the strong, paired hooked thorns are a formidable deterrent on young plants. Twigs which may vary in hairiness from densely puberulous to pubescent or tomentose. Due to its variability the species has been described under many names, some being listed below. ''Senegalia caffra'' is deciduous and older plants are resistant to frost, fire and drought. Its appe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Botswana
The wildlife of Botswana refers to the flora and fauna of this country. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many different species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants. Three national parks and seven game reserves stretch over 17% of Botswana's land area. The three national parks are the Chobe National Park, the Nxai Pan and Makgadikgadi National Park and the Kgalagadi Transfrontier Park. The seven game reserves are the Central Kalahari Game Reserve, Gaborone Game Reserve, Khutse Game Reserve, Mannyelanong Game Reserve, Maun Game Reserve and Moremi Game Reserve. In ...

Flora Of Namibia
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of South Africa
The wildlife of South Africa consists of the flora and fauna of this country in southern Africa. The country has a range of different habitat types and an ecologically rich and diverse wildlife, vascular plants being particularly abundant, many of them endemic to the country. There are few forested areas, much savanna grassland, semi-arid Karoo vegetation and the fynbos of the Cape Floristic Region. Famed for its national parks and big game, 297 species of mammal have been recorded in South Africa, as well as 849 species of bird and over 20,000 species of vascular plants. Geography South Africa is located in subtropical southern Africa, lying between 22°S and 35°S. It is bordered by Namibia, Botswana and Zimbabwe to the north, by Mozambique and Eswatini (Swaziland) to the northeast, by the Indian Ocean to the east and south, and the Atlantic Ocean to the west, the coastline extending for more than .

Flora Of Zimbabwe
The wildlife of Zimbabwe occurs foremost in remote or rugged terrain, in national parks and private wildlife ranches, in miombo woodlands and thorny acacia or kopje. The prominent wild fauna includes African buffalo, African bush elephant, black rhinoceros, southern giraffe, African leopard, lion, plains zebra, and several antelope species. The introduction of the Wildlife Conservation Act of 1960 resulted in checking the loss of wildlife in Zimbabwe, since the 1960s. In the 1990s, it became one of the leading countries in Africa in wildlife conservation and management with a reported income generation US$300 million per year from the protected areas of the state, rural community run wildlife management areas and private game ranches and reserves. The Parks and Wildlife Board consisting of 12 members is responsible for this activity and deciding on policy issues under the Ministry of Environment and Natural Resources Management.

Taxa Named By Adolf Engler
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
