Grewia Flava
''Grewia flava'', the brandy bush, wild currant, velvet raisin, or raisin tree, is a species of flowering plant in the family Malvaceae, native to southern Africa. A common shrub species, it is spreading into grasslands due to human rangeland management practices, and increasing rainfall. The berries, which are yellowish-brown and slightly lobed, are sweet and edible, but have little flesh and so are typically collected in large quantities to be eaten raw, dried or fermented into alcoholic beverages. The wood has a number of uses such as for making bows, knobkerries, traps and other tools. The desert truffle ''Kalaharituber pfeilii'' is often found in association with its roots.

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss people, Swiss botany, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malvaceae
Malvaceae (), or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include Theobroma cacao, cacao, Cola (plant), cola, cotton, okra, Hibiscus sabdariffa, roselle and durian. There are also some genera containing familiar ornamentals, such as ''Alcea'' (hollyhock), ''Malva'' (mallow), and ''Tilia'' (lime or linden tree). The genera with the largest numbers of species include ''Hibiscus'' (434 species), ''Pavonia (plant), Pavonia'' (291 species), ''Sida (plant), Sida'' (275 species), ''Ayenia'' (216 species), ''Dombeya'' (197 species), and ''Sterculia'' (181 species). Taxonomy and nomenclature The circumscription of the Malvaceae is controversial. The traditional Malvaceae ''sensu stricto'' comprise a very homogeneous and cladistically Monophyly, monophyletic group. Another major circumscription, Malvaceae ''sensu lato'', has been more recently defined on the basis that genetics studies ha ...

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."

Kalaharituber Pfeilii
''Kalaharituber'' is a fungal genus in the family Pezizaceae. It is a monotypic genus, whose single truffle-like species, ''Kalaharituber pfeilii'', is found in the Kalahari Desert, which spans the larger part of Botswana, the east of Namibia and the Northern Cape Province of South Africa. Taxonomy The fungus was first described scientifically in 1895 by German mycologist Paul Christoph Hennings as ''Terfezia pfeilii''. It was moved to its own genus in 2005 by James Trappe and Varda Kagan-Zur. Description Fruiting bodies can be up to in diameter. These weigh approximately , although larger rains (which affect weight) can cause them to weigh twice as much. These fruits grow close to the surface, which causes surface cracks on the ground above after rains. These fruiting bodies can occur as much as 40 cm away from the main hyphae. Habitat ''Kalaharituber pfeilii'' is found the Kalahari Desert, as well as in other arid regions of South Africa, Angola, Botswana and Na ...

Acmaeodera Viridaenea
''Acmaeodera'' is a genus of beetles in the family Buprestidae, a group of metallic wood-boring beetles favored by insect collectors. Whereas most beetles including most buprestids fly with their elytra held out and vibrating their hindwings to give lift and thrust, ''Acmaedodera'', however, fly with their hind wings only — the elytra are fused down the center and form a shield over the insect's abdomen, even during flight. This fact, combined with the banding across the abdomen which is common (though not universal) in this family, gives many of them a distinct wasp-like appearance when in flight. Several are therefore considered hymenopteran mimicry, mimics. Species The genus contains the following species:Bellamy, C. L. (2010) A Checklist of World Buprestoidea.

Grewia
''Grewia'' is a large flowering plant genus in the mallow family (biology), family Malvaceae, in the expanded sense as proposed by the Angiosperm Phylogeny Group. Formerly, ''Grewia'' was placed in either the family Tiliaceae or the Sparrmanniaceae. However, these were both not monophyletic with respect to other Malvales - as already indicated by the uncertainties surrounding placement of ''Grewia'' and similar genera - and have thus been merged into the Malvaceae. Together with the bulk of the former Sparrmanniaceae, ''Grewia'' is in the subfamily Grewioideae and therein the tribe (biology), tribe Grewieae, of which it is the type genus. The genus was named by Carl Linnaeus, in honor of the botanist Nehemiah Grew (1641-1712) from England. Grew was one of the leading plant anatomists and microscope researchers of his time, and his study of pollen laid the groundwork for modern-day palynology. Ecology and uses Several Lepidoptera caterpillars are found to feed on ''Grewia'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Angola
The wildlife of Angola is composed of its flora and fauna. An atlas of the amphibians and reptiles of Angola was published in 2018, and reported 117 species of amphibians and 278 of reptiles. A major book on the biodiversity of Angola was published in 2019, and reported more than 2,000 species of organisms (plants, invertebrates and vertebrate animals), and 1,313 fossil species. Fauna Mammals Birds The avifauna of Angola includes a total of 983 species, of which 14 are endemic, 1 has been introduced by humans, and 4 are rare or accidental. 20 species are globally threatened. The western Angola Endemic Bird Area has 14 range-restricted species. Little is known about the conservation status of the region's birds due to the Angolan Civil War from 1975 until 2002. The greatest diversity of restricted-range species is found in Cuanza Sul Province, and given the uncertainty about their current status, many of these species are listed as threatened species, threatened.

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 ...

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, Panthera leo melanochaita, lion, plains zebra, and several antelope species. The Wildlife Conservation Act of 1960 decreased the loss of wildlife in Zimbabwe. In the 1990s, Zimbabwe became a leader in Africa of wildlife conservation and management. In 2006 the country reported generating US$300 million yearly from its wildlife in protected areas, rural and community run wildlife management areas, and in private game ranches and reserves. The 12-member Parks and Wildlife Board is responsible for this activity and deciding on policy issues under the Ministry of Environment and Natural Resources Management. The Zimbabwe Parks and Wildlife Management Authority under the board has the onerous task ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Southern Africa
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. 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) wa ...
