Aloe Albida
''Aloe albida'' is a dwarf species of succulent plant. Characteristics Its flowers are small, white and borne on a single inflorescence. Its flowering time is usually in early autumn (March–April in the Southern Hemisphere), although it may begin to flower as early as February. The leaves form a rosette and have a waxy coating, which gives them a pale greyish/bluish green colour. Habitat It grows in montane grassland and in crevices among rocks where grasses are kept fairly short. It is found on the mountains in Barberton in Mpumalanga Province of South Africa to the northern border, of as well as parts of Eswatini (Swaziland). See also *''Aloe'' *Asphodelaceae *Succulent plants In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions.

Otto Stapf (botanist)
Otto Stapf FRS (23 April 1857, in Perneck near Bad Ischl – 3 August 1933, in Innsbruck) was an Austrian born botanist and taxonomist, the son of Joseph Stapf, who worked in the Hallstatt salt-mines. He grew up in Hallstatt and later published about the archaeological plant remains from the Late Bronze- and Iron Age mines that had been uncovered by his father. Stapf studied botany in Vienna under Julius Wiesner, where he received his PhD with a dissertation on cristals and cristalloids in plants. 1882 he became assistant professor (''Assistent'') of Anton Kerner. In 1887 he was made '' Privatdozent'' (lecturer without a chair) in Vienna. He published the results of an expedition Jakob Eduard Polak, the personal physician of Nasr al-Din, the Shah of Persia, had conducted in 1882, and plants collected by Felix von Luschan in Lycia and Mesopotamia Mesopotamia ''Mesopotamíā''; ar, بِلَاد ٱلرَّافِدَيْن or ; syc, ܐܪܡ ܢܗܪ̈ܝܢ, or , ) is a ...

Montane Grassland
Montane grasslands and shrublands is a biome defined by the World Wildlife Fund. The biome includes high elevation grasslands and shrublands around the world. The term "montane" in the name of the biome refers to "high elevation", rather than the ecological term which denotes the region below treeline. This biome includes high elevation (montane and alpine) grasslands and shrublands, including the puna and páramo in South America, subalpine heath in New Guinea and East Africa, steppes of the Tibetan plateaus, as well as other similar subalpine habitats around the world. The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the And ...

Plants Described In 1933
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Succulent Plants
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulent plants may store water in various structures, such as leaves and stems. The water content of some succulent organs can get up to 90–95%, such as '' Glottiphyllum semicyllindricum'' and '' Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in alpine ecosystems growing in rocky soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist and dew, which makes them equipped to su ...

Asphodelaceae
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is ''Asphodelus''. The family has a wide but scattered distribution throughout the tropics and temperate zones. Many of the species are cultivated as ornamentals. A few are grown commercially for cut flowers. Two species of '' Aloe'' are grown for their leaf sap, which has medicinal and cosmetic uses. ''Xanthorrhoea'' is endemic to Australia. Description Members of the Asphodelaceae are diverse, with few characters uniting the three subfamilies currently recognized. The presence of anthraquinones is one common character. The flowers (the inflorescence) are typically borne on a leafless stalk ( scape) which arises from a basal rosette of leaves. The individual flowers have jointed stalks ( ...

Aloe
''Aloe'' (; also written ''Aloë'') is a genus containing over 650 species of flowering succulent plants.WFO (2022): Aloe L. Published on the Internet;http://www.worldfloraonline.org/taxon/wfo-4000001341. Accessed on: 06 Nov 2022 The most widely known species is '' Aloe vera'', or "true aloe". It is called this because it is cultivated as the standard source for assorted pharmaceutical purposes. Other species, such as ''Aloe ferox'', are also cultivated or harvested from the wild for similar applications. The APG IV system (2016) places the genus in the family Asphodelaceae, subfamily Asphodeloideae. Within the subfamily it may be placed in the tribe Aloeae.Stevens, P.F. (2001 onwards).Asphodelaceae. ''Angiosperm Phylogeny Website''. Retrieved 2016-06-09.

Eswatini
Eswatini ( ; ss, eSwatini ), officially the Kingdom of Eswatini and formerly named Swaziland ( ; officially renamed in 2018), is a landlocked country in Southern Africa. It is bordered by Mozambique to its northeast and South Africa to its north, west, south, and southeast. At no more than north to south and east to west, Eswatini is one of the smallest countries in Africa; despite this, its climate and topography are diverse, ranging from a cool and mountainous highveld to a hot and dry lowveld. The population is composed primarily of ethnic Swazis. The prevalent language is Swazi (''siSwati'' in native form). The Swazis established their kingdom in the mid-18th century under the leadership of Ngwane III. The country and the Swazi take their names from Mswati II, the 19th-century king under whose rule the country was expanded and unified; its boundaries were drawn up in 1881 in the midst of the Scramble for Africa. After the Second Boer War, the kingdom, under the name of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mpumalanga
Mpumalanga () is a province of South Africa. The name means "East", or literally "The Place Where the Sun Rises" in the Swazi, Xhosa, Ndebele and Zulu languages. Mpumalanga lies in eastern South Africa, bordering Eswatini and Mozambique. It constitutes 6.5% of South Africa's land area. It shares borders with the South African provinces of Limpopo to the north, Gauteng to the west, the Free State to the southwest, and KwaZulu-Natal to the south. The capital is Mbombela. Mpumalanga was formed in 1994, when the area that was the Eastern Transvaal was merged with the former bantustans KaNgwane, KwaNdebele and parts of Lebowa and Gazankulu. Although the contemporary borders of the province were only formed at the end of apartheid, the region and its surroundings has a history that extends back thousands of years. Much of its history, and current significance is as a region of trade. History Precolonial Era Archeological sites in the Mpumalanga region indicate settlement b ...

Barberton, Mpumalanga
Barberton is a town in the Mpumalanga province of South Africa, which has its origin in the 1880s gold rush in the region. It is situated in the De Kaap Valley and is fringed by the Makhonjwa Mountains. It is south of Mbombela and east of Johannesburg. Barberton was the seat of the Umjindi Local Municipality until the day of the 2016 Municipal Elections, when the Umjindi Local Municipality was merged into the Mbombela Local Municipality. History Prehistoric The mountains around Barberton are amongst the oldest in the world, dating back 3.5 billion years, and these mountains include some of the oldest exposed rocks on the planet. These volcanic rocks, which scientists call the Barberton Greenstone Belt, have given direct evidence of the conditions of life on the surface of the very early Earth. In the satellite image, the bare rocks of mountain peaks appear as a pale gray-green, accentuated by the sharp relief of sunlit slopes and their shadows. Deeper shades of green ind ...

Grass
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. Ano ...

Gilbert Westacott Reynolds
Gilbert Westacott Reynolds (10 October 1895 Bendigo - 7 April 1967 Mbabane), was a South African optometrist and authority on the genus ''Aloe''. Gilbert Reynolds arrived in Johannesburg with his parents in 1902, where his father started business as an optician. He received his education at St John's College where he was Victor Ludorum. After the outbreak of World War I he enlisted and saw active service in South West Africa and Nyasaland with the rank of captain. Having qualified as optometrist he joined his father's practice in 1921. Reynolds developed a keen interest in the bulbs and succulents of South Africa at about this time. When he started his own country practice about 1930, he was able to travel extensively and gradually narrowed his interests to ''Aloe''. Reynolds was guided in the early stages of his research by Dr I. C. Verdoorn and Dr R. A. Dyer of the Botanical Research Institute in Pretoria, later becoming the authority on ''Aloe'' and having an extensive kno ...
